St. Paddy’s Day Photo Booth

clip sheet photo booth

st paddys day photo boothI’ve  always loved St. Paddy’s day, and then I lucked out and married a cute Irishman. We spent part of our honeymoon in Ireland, and the green island holds a special place in my heart.

A few weeks ago I asked the Tinkerlab Facebook community for some ideas on what I could do with a huge pile of old sheets. I got tons of great ideas, and we started by making a Simple Clip Fort. I’m working my way through the list, and today we’re making a photo booth backdrop for St. Patty’s Day.

Before going to bed I hung a white sheet over one of our curtain rods and secured it with two big clips.

cut out shamrocks for photo boothI cut a handful of shamrocks from green paper and placed them on a table with double-stick tape. Altogether, the prep took me about 10 minutes. When my kids woke up, they were excited about the invitation, got dressed in greenish clothes, and we got right to work.

tape shamrocks for photo boothI helped 3-year old N stick some tape to the back of the shamrocks. Double-stick tape is tricky stuff for little hands! Then she and my 1-year old stuck them to the sheet. Well, my 1-year old mostly tore the shamrocks in half and we had to find a more constructive activity to distract her for a few minutes.

I moved a green rug over to the curtain area and that’s when the dance party started. I snapped a couple archive-worthy photos for the family photo album, and then it was mostly just playing in fron to the clover curtain.

st pattys photo boothOn St.Patty’s Day itself, we serve up green milk in mugs, delivered with a bit of magic. We add a couple drops of green food coloring in the bottom of a dark mug, the kids say “Sean Beggorrah,” and then we pour white milk into the mug for a leprechaun-delivered surprise. This tradition comes down through my husband’s family and I haven’t met anyone else who does this. Is this part of your St. Patrick’s Day traditions?

We’ve been talking about building a leprechaun trap, but I’ve never built one before. Have you? Do you have any tips? And I’m always thinking about fun ways to add magic to this holiday and would love to hear how you celebrate St. Paddy’s Day with your kids.

Are Black Markers Really Black? A Chromatography Lesson.

add water to marker on paper towel experiment

are black markers really black chromatographyWhat color is black? Is it one color or many colors combined to “look black”?

Black is the absence of all reflective colors, and when the three primary colors (red, yellow, and blue) are combined in just the right way, they give off the appearance of black.

We set off to find out more about the predominant colors in our black Crayola marker, and to do this we had to separate the colors. The chemical technique used to separate dyes, pigments, or colored chemicals is known as chromatography. 

This activity can take anywhere from 5 minutes to 25 minutes, depending on how much experimenting your child wants to do, and it’s appropriate for kids ages 2 and up. It’s so simple to do, and would be a natural addition to a morning or afternoon of drawing with markers.

Materials

  • White paper towels or white coffee filters
  • A Plate
  • Black marker/s
  • Water
  • Water Dropper

add water to black ink

We started by drawing a big quarter-sized dot on the paper towel, and then squeezed water on top of it. The colors that are released into the paper towel give you some clues as to what goes in to your black. In our case, there was a lot of green.

add water to marker on paper towel experimentAfter the black marker test, 3-year old N wanted to test the rest of her markers. She made a lot of predictions, and they all came out as expected (yellow appeared to be yellow and green was made from green dyes).

add water to marker on paper towel experiment

The red and pink, however, stumped her as they both released a pink color.

More Chromatography

For older kids, this slightly more advanced version of our kitchen experiment from Science Project Lab has some pretty cool results.

Kids will be amazed at the rainbow of colors released by leaves in this chromatography experiment shared over on TLC Family.

I like this coffee filter chromatography project from Kids Make Things.

Sensory Activity: Shredded Paper

brown-bag

If you’re afraid of a mess, I have to warn you up front that this is a messy one.

But it’s not a dirty kind of mess and if you stick with me here, you might become a shredded paper convert like me.

paying bills with kidsIt all started innocently, and rather boring, enough. It was a bill-paying day, and I set the kids up with their own stack of mailing labels stickers, pens, and old checkbooks while I dealt with the heavy stuff.

They were happy enough, but things heated up when we moved on to paper shredding

shredding paper in paper shredder with kids

I had basket full of old bills that were ready for the shredder, and two happy-to-please assistants who took the shredding job very seriously.

Shredders are potentially dangerous, and I would absolutely not let my kids shred on their own, but with careful supervision the act of shredding can build confidence, teaches accuracy and careful attention to details, and it’s just plain fun to make a loud ruckus.

When it’s not in use, I unplug the machine and lock it in a closet. When it’s in use, I run through the rules of good shredder usage with my three and a half year old: Up to 3 sheets at a time. Hold the paper at the top when you feed it in (no fingers near the shredding area). And it’s not for my 18 month old.

While my three year old shreds, her sister hands her stacks of paper. They love it.

Okay, so take a look at that little basket of paper up there and remember how small it appears. And remember that appearances can be deceiving.

My friend and her son came over a couple hours later to play and make some ice cream. While we were talking, my 18 month old dug her hands deep into the neatly packed shredded paper bag, and in moments the room erupted into this happy play scene…

play in shredded paper with kids

And that’s only half of the paper.

They could not have been happier. In fact, just before this moment, the kids were all winding down and ready to go their separate ways. But as soon as that bag emptied out, they found a whole other hour of play inside their little souls.

It was so fun, in fact, that my older daughter chose to keep playing rather than go to her beloved gymnastics class.

play in shredded paper with kidsMy friend is a master at imaginative play with kids, and had them bury themselves in shredded paper, pretend they were dormant volcano monsters, and then erupt without any notice. You can probably imagine the shrieking and laughter that followed.

And we all agreed that this is the perfect toy: free, open-ended, and entertaining for a long spell.

So it was messy, yes, but it was easy enough to sweep up. And rather than cart it off to the recycling bin like I had planned, it all found its way back into the closet and ready for another day of fun.

5 Easy Steps to Invent a Recipe with Kids

invent a recipe with kids

Do you like to cooking with kids or do you yearn to cook with your child? Today we’re sharing five easy steps to invent a recipe with kids, which will get you into a creative cooking mindset. Think Master Chef + little kids = a fun afternoon.

But you might wonder, “why would I want to invent a recipe when I can easily follow a recipe?” The answer is that inventing recipes instills children with confidence to invent their own solutions to a problem, encourages independent thinking and problem solving skills, and teaches children how to find their way around a kitchen.

5 easy steps to invent a recipe with kids | TinkerLab

My house smells like pancakes.

Which really means that it smells like cooking oil and caramelized sugar. Sort of a happy, greasy smell that has lingered for days.

Every afternoon, for the past three days, my 3 year old turns into a kitchen alchemist as she gathers ingredients and invents her own recipes.

She is in heaven. And it gets even better once we cook the cakes up and proudly serve them up to hungry family members.

Do you ever give your kids free reign over your kitchen?

Experiments like this set children up with a real-life science experiment that fosters creativity, inventiveness, and problem-solving skills. It’s not for the faint of heart and you have to be okay with a bit of a mess, but I think the trouble is well worth it for the amount of creative confidence it builds in children.

So, after three straight days of wild pancake combinations, I present five lessons learned on how to invent recipes with kids…

Cooking with Kids: Invent a Recipe

How to Invent a Recipe with Kids | TinkerLab

Lesson #1…Get Familiar with the Kitchen.

If your child doesn’t know where things are, give him a little tour. And start with a simple cooking project that introduces him to some key ingredients and tools for a favorite recipe (such as a mixing bowl, mixing spoon, measuring spoon/cup, flour, and oil).

We spend a lot of time cooking together and my oldest (N) knows her way around the kitchen. She can find the biggest mixing bowl in the house, all the baking ingredients are at kid-level (this will no doubt pose a problem once her little sister figures this out), and we have amazing little foldable step stools like these that give her access to the fridge (unless she wants the butter…but we do have a taller stool for that).

How to Invent a Recipe with Kids | TinkerLab

Lesson #2…Come up with a General Plan.

In our case, N has been making pancakes, pancakes, and more pancakes. We tend to make a lot of pancakes in our house anyway (they’re not just for the weekends), so she’s super-familiar with the key ingredients and general direction of what might taste good together. For example, she didn’t pour ketchup into the batter (although if she did, I probably would have let it happen).

Do you have a favorite family recipe that you could riff off of? 

To start, she collected a few ingredients (white flour, wheat flour, flax seeds, and blueberries), and added them to the bowl. I tried to step back and allow her to make decisions about quantities, but every now and then I’d throw out a suggestion to help guide the journey.

As you can imagine, her pancake recipe has WAY more than the usual tablespoon of sugar (see the next picture), but it turns out that sugary pancakes are absolutely delicious.

Lesson #3…Green Light all Ingredients.

Of course you want to be safe about this, as things like raw meat and raw eggs need special handling, but try to keep an open mind as your child selects her ingredients. One of N’s batters had chocolate chips, white chocolate chips, mango juice, dried cranberries and walnuts in it. It was amazing.

The most recent batch contained raspberries, strawberry cream cheese, diced apples, and goat cheese. It was a bit chunky, and I’m not so sure about the goat cheese, but we drafted a recipe in case they end up being the best one yet.

Which bring me to the next lesson…

Lesson #4…Write the Recipe Down.

This is validating and makes the whole game so much more fun. As N added ingredients, I tried my best to write them down. Some things were carefully measured and others weren’t, but it didn’t really matter. I’m thrilled to have documentation of her first recipes and I’m sure she’ll treasure them as she gets older.

Lesson #5…Embrace a Good Experiment.

As we cooked, I repeated multiple times that this is a grand experiment and that we’d be surprised one way or the other. We chatted about how it’s possible that not one person has ever made this exact recipe, and that chefs go through a similar process when they invent something new. Like scientists, they hypothesize (what ingredients might taste good together?), they experiment (let’s make this batter with yogurt and the next with sour cream), and they test (how does it taste? which batch do we like better? why?).

After one of our cooking sessions, my husband took the kids off on a run in the stroller. These two hot cakes were eaten before they left the driveway, which I suppose speaks to how delicious they came out.

How do you involve your kids in the kitchen? Have you tried letting them loose with ingredients? How did it go?

Magical Plastic Bag Experiment

leak proof plastic bag experiment

Magical Plastic Bag Experiment | TinkerLab

Here’s a fun experiment that won’t take a lot of time, and it’s more than likely that you have all the “ingredients” around the house. I did this with my three and a half year old, and it would be relevant for preschoolers and elementary-age children.

The idea that we’re testing here is what will happen if we poke a sharp pencil through a plastic bag of water. Will the water leak through the holes? Will the water spill out? Or will the bag reseal around the pencils, keeping the water inside?

When my 3-year old daughter (N) and I tried this out, we worked with the question, “what will happen if we poke pencils into a bag full of water?” That seemed more age-appropriate and tangible for her.

Magical Plastic Bag Experiment | TinkerLab

 Materials

  • Zip-up Bag
  • Water
  • Sharpened Pencils

We filled a zip-up bag about half-way with water and sealed it up. I held the bag high over a sink and N poked the pencils straight through the bag, from one side to the other. This is where my fancy photography skills come into play, holding the bag with one hand and snapping a photo with the other. Are you impressed?

Make sure that the pencil doesn’t keep traveling through the bag or you’ll have water leaks.

Magical Plastic Bag Experiment | TinkerLab

Keep adding pencils until you’ve had enough. Before removing the pencils, take a moment to talk about what you see. When the pencil goes into the bag, the bag seems to magically seal itself around the pencil.

Magical Plastic Bag Experiment | TinkerLab

When you’re done, remove the pencils over a sink.

The Science Behind the Experiment

Plastic bags are made out of polymers, chains of molecules that are flexible and give the bag its stretchiness. When the sharp pencil pokes through the bag, the stretchy plastic hugs around the pencil, creating a watertight seal around the pencil…and the bag doesn’t leak.

More Polymer Fun

Now I’m really excited for us to try poking skewers through balloons without popping them (QuestaCon Science Squad) and make our own kazoos from toilet paper rolls and plastic bags (Kazoologist). Steve Spangler Science is also an amazing place to go for projects like this, and you’ll find endless polymer-related ideas over there.

You could also make your own polymer by mixing up a batch of fun and flubbery Gak (a mixture of water, white glue, and borax). We’ve done this multiple times, and my kids can’t get enough of it.

DIY Paper Bag Book with Japanese Binding {Free Download}

Tinkerlab DIY Paper Bag Book cover.001

You might know that I’ve been working on a fun project with the San Francisco Children’s Creativity Museum DIY Studio Space. Each month for a full year, we’re developing creativity-boosting invitations for children who visit the museum. If you visit the Studio this month you’ll find an assortment of interesting found materials and a host of ideas for upcycling books from these materials.

And in case you didn’t make it to the CCM this month, I’m giving away a free project download: Tinkerlab DIY Paper Bag Book

The cover is made from a paper lunch bag, the inner pages are made from any paper you like, and it’s bound with a traditional Japanese 3-hole binding that elementary-age children could do with a little assistance.

Children will work through spatial reasoning and learn about a traditional binding method through the process of binding. They will also explore different recycling possibilities through the selection of materials. And once the book is made, children can fill it with sketches, stories, stickers…the possibilities are endless.

This is new to me and I’d love to hear your thoughts: Would you rather see all the steps in a blog post or do you like having it in a sweet and tidy PDF?

Is it Magnetic? Testing Objects for Magnetism.

magnets and water

How was your weekend? We took a mini-vacation to play in the snow and I enjoyed a little computer break along the way. I thought I could get online with my phone, but it turned out that the reception was horrible and I’ve been completely out-of-touch! It was probably a good thing, as I could really focus on my family and be as rested as possible when my one-year old woke up, inconsolable, for 2 hours in the middle of the night! I also want to formally thank my good friend Melissa from The Chocolate Muffin Tree who checked in to make sure I was okay! How lucky am I?

I’ve been on a science kick lately. Maybe because my 3-year old is completely self-serve in the art department or maybe because I’ve checked every science for kids book out of our local library? If you’re in the market for a great book of kids science experiments for ages 8 and up, I checked out The Science Explorer Out and about: Fantastic Science Experiments Your Family Can Do Anywhere (Science Explorer Out & about)and it’s phenomenal. It was written in 1997 and looks a little bit dated, but the concepts are solid and it stands the test of time. If you’ve ever been to San Francisco’s Exploratorium or if you’re familiar with their publications, you’ll feel connected to this book.

magnet and water experiment materials

Today’s experiment is similar to one we’ve done before with paper clips +magnets (Traveling Magnets), and this takes it up a notch with a few more magnet surprises and discoveries. Here’s what you’ll need…

Materials

  • Glass or vase of water. Thin glass works better than thick.
  • Pipe cleaners and/or paper clips
  • Strong magnets
  • Scissors
  • Small magnetic and non-magnetic objects

pipe cleaners in water experiment

Cut the pipe cleaners up and add them to the vase of water and mix them up so the pipe cleaners sink. Three-year old N loved doing this step herself.

Using your magnet/s try to pull the pipe cleaners up the side of the vase. Once they reach the top, you can retrieve them or drop them back in.

It’s like fishing!

testing magnets experiment kids

This opened up a conversation about what would stick to the magnets, so I pulled out a handful of small metal and non-metal objects for us to test.

Meanwhile, my 1-year old enjoyed stirring the water and fishing pipe cleaners out with her hands.

testing magnets experiment kids

N understood that the magnet would only stick to metal and quickly ruled out rubber bands and post-it notes from the “Is it magnetic?” list, but we also learned that the magnet wouldn’t stick to ALL metals.

And that was a surprise!

magnets on hardwood floor nails

One of the funnest surprises, however, was when a magnet fell onto the floor and stuck to a hidden nail! We dropped the rest of our magnets onto the floor and flicked them from nail to nail, watching them dance from floorboard to floorboard.

One more thought — I kept a close eye on my 17 month old throughout because our magnets are so tiny — just a thought that you might want to do the same or find some big magnets for the under 3 y.o. crowd.

What did your weekend look like? Have you been able to take a technology break? And have you had any fun magnet discoveries?

 

 

The Cutest Crayons You Ever Did See {Giveaway}

stars

Isn’t this the cutest lil’ box of crayons you ever set your eyes on? I learned about Melissa of Earth Grown Crayons from a comment she left on my Facebook page, and can I just tell you how happy I am to have found her? Earth Grown Crayons are handmade (amazing, right?!), all natural, eco friendly and biodegradable. The crayons are made from natural soy wax and nontoxic mineral pigments – more plusses in my book! Melissa was kind enough to send me a box of crayons to review and my kids and I were so excited to find out what was inside.

If you click through to the Earth Grown Crayons Etsy store, you’ll see that we could have been surprised with anything from dragons to strawberries, and we were thrilled to pull the paper back and reveal…

a school of fish!!!

Before she even thought about drawing with the crayons, 17 month old R was content flipping them over over again. They do look like little toys.

She enjoyed this flipping game so much that I brought her a little spatula and pot to practice balancing and hand-eye coordination. Awesome!

Oh, and proof that we also drew with the crayons…

Three year old N gave them a thumbs-up and commented on how bright the colors are. I have to agree.

You could also order a constellation of stars,

…or this sweet woodland animals scene.

In addition to being lovable, the soy crayons have a creamy texture that’s a pleasure to color with. In Melissa’s words:

“Soy is an all-natural, renewable resource that is one-hundred percent biodegradable – making it an earth-friendly choice for kids. Soy beans have been a part of my life since I can remember. Growing up I spent time on my grandparents farm in rural Minnesota. I watched my grandpa plant and harvest soy beans in the fields behind his farm. Now, many years later, I’m making my own creations from soy, inspired by my love for animals and other living things.

My Earth Grown Crayons are made from soy beans free of herbicides and pesticides, and grown on American soil. I use only non-toxic pigments. Crayons come packaged in recycled or reusable materials and are hand-made in a home that strives to be loving of the earth in every way.”

Lucky for us today, Melissa has offered to give away one of her boxes to a Tinkerlab reader. Woop! If you’d like to enter to win, leave a comment by Sunday, February 19, 2012 at 9 pm PST and the winner will be chosen by random number generator. This is open to readers with US addresses only. Good luck!  Thank you to everyone who left a comment. A winner has been selected.

 


All opinions expressed are my own. Aside from receiving a lovely box of crayons,I received no compensation for this post.

6 Kids Valentines Activities and Homemade Valentine Gifts

We’ve been crafting up a Valentine’s storm, which mostly means that three-year old N has been collaging all our self-serve bits and bobs of Valentine goodness into a taped-up, glued, and spackled hodge podge of Valentine craziness. In other words, we’ve been having fun, but it’s not something anyone else would likely take inspiration from or worth blogging about!

That said, we have been playing with an amazing batch of Valentine play dough that’s always good for open-ended exploration and imagination-building. And, for my 1.5 year old, it’s great for hand-eye coordination and fine-motor skill development. 

valentine play dough

I keep my play dough in a big sealable bowl or zipped bag, and it will last for months. I use this recipe, and it’s hands-down the best one out there for the play dough job. Here are the ingredients, but click over to the recipe for all the deets:

valentine play dough station

The Ingredients

  • 2.5 cups water
  • 1 1/4 c. salt
  • 1 1/2 tbsp. cream of tartar
  • 5 tbsp. vegetable oil
  • 2.5 cups flour
  • Food coloring or liquid watercolors. I really like Wilton Icing Colors or Liquid Watercolors (from Discount School Supply), which make gorgeous shades of play dough to match any occasion, mood, or toddler request.

 

For our Valentine Play Dough Station, I made a batch of white dough and a batch of dark pink, and then the kids helped me loosely mix them together to make this fun, mottled Valentine concoction. Oh, and we added peppermint oil to the mix to give it a nice, fresh smell. This would be perfect for Christmas too…something to keep in mind for later.

valentine play dough

I gave my kids a new set of heart-shaped cookie cutters, which proved to be too difficult for my little one to effectively use on her own. But that didn’t stop her from trying! I cut a few shapes for her, which she really enjoyed pulling out of the dough and then breaking into three or four pieces. Some of the hearts were too challenging for her to pull out on her own, so I’d break the dough walls, which helped her remove the hearts somewhat intact.

She also enjoyed playing with the rolling pin and practiced rolling snakes.

valentine play dough

I was recently asked which of our art materials is absolutely indispensable, and while there are many, play dough is one of those materials that appeals to a wide variety of ages because the threshold is so low. Very young children know exactly what to do with it, and as children get older their ability to manipulate it and use it for imaginative play grows along with them.

Play dough, I love you…Happy Valentine’s Day!

Paper Bag Museum

In case you missed yesterday’s post, we’re hosting a super fun Paper Bag Creative Challenge that brought over 50 kid-directed paper bag projects together in one spot. Today I’m excited to share our own take on the challenge.

My one year old colored paper bags with oil pastels and glued hearts and sequins to a paper bag while my 3 year old went to town — all day long — making paper bag collages that quickly took up all the ceiling space in the room.

My 3-year old, N, called these her Valentine Collages and Paper Bag Art. She recently picked up on how museums have multiples of one type of thing, and decided that this would be her Paper Bag Museum. In case you’re wondering, I was told that it was okay that some of the things in the museum weren’t made with paper bags. She’s the curator, so I couldn’t really argue with that.

paper bag museum

We set up a Vistor Services Desk with information about our admission policies and hours. It’s really important for people to know that they can’t hang out in our house at dinner!

paper bag museum

We gathered up all the paper bag creations that weren’t hanging from the beams and displayed them here. Maps are in the basket on the left and she set up an interactive activity in the paper bag “basket.” More on that in a sec.

paper bag museum maps

We talked about how museums share all sorts of informative collateral for visitors to pick up, like maps, schedules, and catalogues. I cut a big paper grocery bag into squares and she decided to turn them into maps. To make this map, we started with a “you are here” dot, and then she added trails into the various rooms of our house, also marked by dots.

paper bag museum maps

But why stop with one map when you’re expected a big audience!

interactive museum prompt with kids

Then she handed me a stack of post-its and dictated this participatory prompt to me.

The museum educator in me was so proud!

This wasn’t going to be some stuffy old museum — oh no, she was thinking about her visitors’ experience and wanted to make sure their voices were heard!

paper bag museum

Our first visitor woke up from her nap just in time for the opening, and got right to work with a drawing. The prompt worked!

The museum is now closed for the installation of a new show. My one year old is enamored by fish, so maybe we’ll figure out a way to build her an Aquarium!

What’s your child’s favorite kind of museum? Could you set up an imaginative play area based on it?

Yeast and Sugar Experiment

yeast experiment

yeast experimentI’ve been baking bread just about every day for the past three weeks (nothing too crazy since it’s all done in the bread maker), but last week my 3.5 year old and I got into a discussion about the properties of yeast.

We like to tinker and  experiment – big surprise, I know — and decided to see what would happen if we mixed yeast with warm water. N took this job very seriously, poured the water into a bowl, added a couple teaspoons of yeast, and waited a few patient minutes before she said, “it makes a brownish color.” True, and to make it bubble like it does in bread, we needed to activate it with sugar.

So we took about fifteen minutes to clear some space and set up what would become the Yeast + Sugar Experiment.

What’s so great about an experiment like this is that it’s easy to do with household materials, and it’s ripe for authentic child-generated questions and observations. When I asked what she thought would happen if we added sugar to the yeast she said, “I don’t know! Let’s mix them and find out!.” And when we finally attached the balloon to the bottle she wondered, “will it fill up all the way and blow off the bottle?”

yeast experimentWhat you’ll need

  • Sugar, 2 tablespoons
  • Active Dry Yeast, 1 packet or 2 1/4 tablespoons
  • Balloon
  • Warm water (105-115 degrees F, 40.5-46 degrees C)
  • Mixing bowl + funnel (we used a cocktail shaker instead)
  • Bottle that you can fit a balloon over

yeast and sugar experimentMix the yeast and sugar into the warm water and stir. I noticed that N was sniffing the concoction and asked her what it smelled like. She said “poop.” I could see what she was saying. Consider yourself warned.

Once it all dissolves, pour the mixture into the bottle and cover the bottle with the balloon.

yeast experimentAfter a few minutes you’ll be amazed by something like this!

yeast experimentN wanted to feel it as it filled with air. She noticed the balloon was getting bigger and wanted to know how big it would get.

yeast experimentMy handy-dandy ship captain sister (no joke — that’s her job!) was visiting, and put herself right to work as chief measurer.

yeast and sugar experimentOnce the bottle filled up completely, we moved the whole operation to the sink. The bubbles were slow-moving, and there was nothing to worry ourselves with, but N enjoyed pulling the balloon off and watching the foam slowly pour over the bottle’s top.

As we went through the process, I thought of a few fun extensions for older kids or those who want to take this further. You could play around with food coloring/liquid watercolors, have a few bottles going at once and compare the results of different sugar:yeast ratios, or compare the results of different water temperatures.

I found my recipe at The Exploratorium’s Science of Cooking series, where we also learned that as the yeast eats the sugar it makes carbon dioxide, which is essentially the same process that yeast goes through in our bread dough.

Mmmmm. I’m off to eat some whole wheat cranberry walnut oat bread. Toasted. With butter and Maldon salt. How do you like your bread? And have you played around with yeast concoctions?

Chalkboard Painted Canvas

Zemanta Related Posts Thumbnail

“Art washes away from the soul the dust of everyday life.” – Pablo Picasso

Chalkboards…I love them. You? The texture, the dust, and contrast are oh-so-appealing.

When I started to see them disappear from classrooms in favor of dry erase boards, I was a little bit shocked. Dry erase boards are wonderful too, but they’ll never have the same rustic appeal as a chalkboard.

This project began when I found a $3 canvas at a thrift store back in September (it had a print of a cow on it — truly hideous), and painted over it with a few layers of black chalkboard paint. Since October, it’s been filled with these house “rules,” and while I enjoyed looking at them, and even managed to inspire a neighbor to add some chalkboard quotes to her own kitchen, I was ready for a fresh start and enlisted the help of my crew to come up with something new.

And maybe I was feeling a little bit guilty on those days that I just ate buttered toast and wanted to spit. Maybe.

So I pulled the canvas down, wiped it clean with a damp rag, and let the kids go to town.

They loved it.

This is how it looked two weeks ago, and then this week we started all over again.

We also have a chalkboard that’s painted right onto part of our kitchen door, and it gets a lot of use for everything from chicken scratches to make-shift calendars to homemade infographics.

We collaborated on this one: the bunny is mine, the yellow is N, and the pink is Baby R. Funny thing, at least for me, is that back when I was brainstorming names for this blog, I called it Chalkbunny for a couple months before landing on Tinkerlab. So here we have a real, live chalk bunny, which is what we decided to call the little character in my new banner.

Do you have a well-loved chalkboard? What makes it special? And how do your kids use it?
