Celery Science Experiment

By Rachelle

While I’m an art educator by trade, having small people pull at my pants has turned me into a mini-alchemist who’s suddenly found herself reading books to her kids about Galileo and brewing all sorts of concoctions in our kitchen (vinegar and baking soda, anyone?). Preschoolers are simply curious and see no boundaries between art and science, making this celery experiment a wonderful early STEAM (science, technology, engineering, art, and math) activity for young children.

The celery science experiment is easy to achieve with basic kitchen materials and it’s embedded with all sorts of opportunities for introducing the scientific method (in short: asking scientific questions, making predictions, and conducting an experiment).

Supplies

Celery with leafy tops
Clear glasses
Water
Food coloring

The Celery Science Experiment

N poured water into three glasses. about 3/4 cup in each.

Then she added a few drops of food coloring — 5-8 drops, but who’s counting! — into the glasses and stirred with a piece of celery, which was left in the glass. And then we talked about what might happen if we left the celery in the colored water for a while.

We oohed and ahhed over the lava-lamp effect of the food coloring as it hit the water.

The Scientific Method: Make Predictions

We started off with red, yellow, and green, but N really wanted to mix colors and added blue and red to the green water (far right). We revisited our earlier discussion and made predictions about how the celery might change.

While waiting for something to happen, I chopped the celery heart off the bottom of the stalk and set up a printing activity.

N humored me by making a few prints and then asked if she could play with colored water. Totally!

While I only have one photo of this, it was probably the highlight of the afternoon.

When we checked the celery a couple hours later, this is what it looked like. I put a leafy top next to it so you can see how subtle the change is. Hmmm. While I could see the change, I wasn’t sure it would make a big impact on my daughter. And then I realized that I should have just put the leafy parts in the water for a more dramatic result. Done!

A few hours later the blue/green had the most pronounced shift, but the red and yellow were visibly different too.

Here’s a side-by-side comparison of the red and blue-green died celery tops, about 16 hours after the stalks had been sitting in the water. N seemed to appreciate the difference, but wasn’t nearly as impressed as her dad and I were.

Why does celery absorb food coloring?

In terms that preschoolers can understand…

Plants need water to survive and they draw water up from their roots through their capillaries. The capillaries are hollow and act a lot like a straw. Adding color to the water helps us visualize this usually invisible process.

Pom Pom Christmas Pinecone Ornament Craft

By Rachelle

The holiday season is upon us and the smells of the season are filling our home with cinnamon, fir, cloves, vanilla, and pine. It’s delightful!

Making Christmas crafts from pine cones is easy, seasonal, and inexpensive. This pom pom Christmas craft can be set up in just a few minutes, clean up is easy, and kids get the chance to exercise their glue gun skills (so fun!). Glue guns and kids? Don’t fret – keep reading for details on how to build glue gun confidence.

Supplies

Low Heat Glue Gun such as Elmer’s Craft Bond Dual Temp
Pinecones
Small Pom Poms
Ribbon or Yarn

Glue guns and kids? Yes! Glue guns enable kids to bring their 3-D visions to life in a matter of seconds, while avoiding the frustration of waiting for white glue to dry. Just be sure to use a glue gun with a low heat setting like Elmer’s Craft Bond Dual Temp. I really like this glue gun because I can flip the switch to high temp (for my mama super-gluing needs) and safely back to low temp for the kids.

Let’s talk pinecones: If you live somewhere where they’re dropping everywhere like they are here in Northern California, bonus! Your pinecones can be found for free! Our new puppy loves chewing on pine cones – this one did not make it to the crafting table.

However, you may not want those lovely sap-infused, rain-drenched pinecones, and the good news is that they’re easy to find this time of year at craft stores. I found a bag of about 20 pinecones, infused with cinnamon, for just a few dollars. I like the natural rustic look, but for a beautiful holiday ornament, you could start with shimmery gold pinecones like these.

Steps

Clear the table and cover it with paper or a table covering if you don’t want the glue to stick to the table. I’d recommend this step if your table is a precious surface.
Plug in the glue gun.
Set up a bowl or plate of pom poms, a few pine cones, and ribbon.
If your child has never used a glue gun, walk through some safety steps on how to use it: don’t touch the tip and don’t touch the glue immediately after it comes out of the glue gun. Make a practice pinecone together to work out any kinks. Patience is so important with this step, so take your time if you need to.
Invite your child to attach pom poms to the pine cone.
Make a loop of yarn and glue it to the top of the pine cone.
Hang your ornament!

Creativity Corner

Sometimes kids will come up with their own ideas that stretch outside the bounds of what you may have in mind. I love these moments and encourage them as they help children develop their independence and imagination. If your child wants to add sequins or buttons instead of pom poms, or wants to wrap the pine cone in ribbon, go for it! This is a great opportunity for playful crafting.

Card Stock paper
Elmer’s Extreme Glue Stick – this glue stick is fantastic for connecting papers that you don’t want to separate.
Scissors
Mark-making tools such as pencil, paint, or paint markers (we used Painters Paint Pens)

Steps for Printable Postcards for Kids

Print postcards on cardstock
Cut out a postcard
Cut out another piece of card stock to match the postcard size.
Glue the postcard to the blank card stock using a heavy duty glue stick. Two pages are necessary, otherwise your card will be flimsy and less postcard-like.
Decorate the blank back with a picture of your travels or uplifting message.
Write your greeting, add an address, stamp, and mail!

Supplies…easy peasy, right?

This step is super important if you want your postcards to feel sturdy enough to mail: Glue a piece of card stock to the back of your postcard with a heavy duty glue stick like Elmer’s Xtreme.

Bring your postcard on your trip, along with art supplies.

We made this a family collaboration– my daughter drew the message and I added color with color-rich Painters paint pens. Read on to see how we finished it off.

We’ve been playing with calligraphy pens lately and picked up the Manuscript Leonardt set (pictured below) for a recent trip. As an aside, I wouldn’t normally recommend an open container of calligraphy ink on a flight (be careful!!), but we had smooth skies and luckily no ink was lost. I added some black ink flourishes.

Once we landed, my littlest added splashes of color with colored pencils, and then our postcard was ready to get shipped off. We’re also using the Progresso Woodless Colored Pencils (such rich colors – amazing! ) and the Koi Watercolor Travel Set (24 colors) (also a travel favorite!).

After a visit to the beach on a windy day, sailboats were in order.

What do you think? Wanna print up a stack and carry them along for impromptu love notes? Of course you do!

How to Make Sun Prints on Fabric

By Rachelle

I’m delighted to introduce you to TinkerLab’s newest contributor, Noreen Greimann, who shares a beautiful article on how to sun print on fabric. I adore this project because it encourages us to spend time in nature and outside, and also uses materials that you probably already have access to.

Growing up, I often lost myself in the natural world spending hours in the garden, the fields and by the river. These special places with all their nooks and crannies became my main source of inspiration for playing, tinkering, writing and drawing.

This hasn’t changed. And now I get to share these moments with my children and watch with amazement how they weave their experiences in nature into their play and creative activities.

Today, I’m excited to show you how to take bits and pieces of nature to create gorgeous sun print fabric that you are going to want to make over and over again.

Supplies

• 100% white cotton fabric
• acrylic craft paint or fabric paint (darker colors recommended)
• paint brushes
• water in a bowl or small bucket
• a flat surface outdoors to work on (e.g. driveway, old cutting board) – no wooden surface
• nature materials: petals, leaves, ferns, blades of grass, flat pebbles, etc.

Directions

Make Paint. Dilute the paint with water at a 1:1 paint to water ratio. You want the paint to be thin enough to flow easily, but to still have enough pigment for bright colors.
Wet the Fabric. Wet the fabric in a bowl of water and squeeze it out until it is no longer dripping. Lay it flat on a mat or other non-porous surface.
Paint the fabric with a big paintbrush. When working with young children it is best to only use one or two colors at a time. Otherwise, the results will be rather muddy looking because little hands often can’t resist mixing all the colors together.
Press the leaves and flowers. As soon as you are done painting, press the leaves and flowers top side down onto the painted fabric, making sure the edges of the leaves and flowers lie flat. The more contact with the fabric, the sharper the lines will be in the end.
Place in the sun. Leave the fabric out in the sun for 1 to 2 hours. If it is really hot, it helps to mist the fabric during the first 30 minutes to an hour.
Remove leaves. When the fabric is completely dry, peel off the leaves and flowers and watch the magical prints appear. Don’t the dandelion leaf prints look like fish?
Set the paint. To set the paint, place the fabric in the dryer on high for 1 hour. I also recommend hand washing the first time as some of the paint may still wash out.

How to use sun print fabrics

The possibilities are truly endless.

Start with a t-shirt or pillowcase and you will have a stunning project in 2 hours.
Fabric pieces can be sewn into simple draw-string bags, which are perfect for holding gems, fairies, acorns, pebbles, seashells and other treasures. The fabrics also make lovely doll pillows and blankets.
Or how about a large bag for carrying books to the library?

Ready to give this a try? I hope you will enjoy this project as much as we do.

Hand Painted Wrapping Paper for Kids

By Rachelle

There’s nothing quite as precious as a homemade gift, and even more so if it’s wrapped up in hand painted wrapping paper. We used this wrapping paper to wrap homemade soap for Mother’s Day, and you could use this for just about any gift.

This is a fun and practical way to help kids learn about absorbent paper. Following this activity you can experiment with coffee filters, doilies, paper towels, tissues, or coffee filters again.

Ages: 2 and up

Benefits and Skills: Fine motor, experimentation, play, connection, curiosity

Supplies

This list contains affiliate links.

Liquid watercolors
Paintbrushes
Pipette or medicine dropper
Packing Paper to paint on
Paper to cover work surface
Large sheets of newspaper or packing paper for paintings to dry on
Containers for paint – we used baby food jars and an ice cube tray

The Set Up

Cover your work area
Set up tissue paper, paint, pipettes, and brushes.
Invite your child to paint
Once the painting is done, move it to dry on a sheet of newspaper or packing paper. For extra fun, use kitchen tongs to move the work.

Note: You can set all of this up outside or in a large cookie sheet like this if you’re worried about your child squeezing paint all over the table.

Questions to Ask

What will happen if we squeeze paint on this paper?

What colors do you want to paint with?

I wonder what will happen if the blue and yellow paint mix together?

Once your paper is dry, use it to wrap up homemade gifts.

Shoelace Manifestos

By Rachelle

We were invited by Famous Footwear to participate in their Step Forward campaign, which celebrates creativity, being our best selves, and stepping forward with confidence. I’m a big champion of encouraging self-confidence in kids, and this is a message I can easily stand behind. The TinkerLab philosophy is rooted in giving children voice, supporting their individuality, and encouraging self-expression, so of course I had to look to some kids, which happened to be my own, for direction on this project.

These are the questions that guided us:

How can we encourage children to be their best selves and step forward with confidence?

What do they care about?

What are their dreams?

All sorts of ideas were brewing in my mind, mostly along the lines of painting or stenciling our shoes with brave colors or bold messages, but again, I wanted my kids to take the lead on this one. After all, following a child’s curiosity is a tenet of my philosophy as both a parent and arts educator.

So I posed this question to my girls:

“How can we celebrate our personalities through our shoes?”

And that’s when my 8-year old suggested that we make Shoelace Manifestos.

Ohhhh, I love this idea so much, and it’s so her!

She loves to write affirmations and positive statements in her journals, so we decided to celebrate this.

But how? She suggested square letter beads as a way to create a mini shoelace billboard of our affirmations.

#shoelacemanifesto

man·i·fes·to

/ˌmanəˈfestō/

Noun:a written statement declaring publicly the intentions, motives, or views of its issuer. (Merriam-Webster)

This quote by French fashion and shoe designer, Roger Vivier, is a lovely sentiment for this project:

“To wear dreams on one’s feet is to begin to give a reality to one’s dreams.”

Like so many children, my kids love their sneakers, and so we all decided to bead up new shoes from Famous Footwear.

My 8-year old and I both chose classic Chuck Taylors. I haven’t owned a pair of these since college, but oh-how-I-loved-these. It’s so fun to get my feet in these again. Swoon!

My 6-year old fell madly in love with these Roxy Rizzo shoes, and practically wore them into the ground before I had a chance to shoot these photos, but it’s a sign of how much she enjoys them.

They are the cutest and get tons of compliments…especially when clean. 😉

We set up the shoes for inspiration, and filled a bowl with these beads.

I didn’t give the kids any guidance and was curious to see where they would take this. My 6-year old spelled out NEW YORK. I asked her about it later and she told me that she loves New York. Not all the noise, but the tall buildings.

After lacing these up, we took them for a ride on the swing. To give them some air and speed in true New York fashion.

My 8-year old adores reading and came up with this message: I ❤️ READING.

She really does. In fact, after pulling this together, she quietly snuck away and happily curled up with a book.

My initials are RAD, which I love, so I knew I wanted the word RAD on one shoe, and my kids suggested SOUL for the other. They’re into puns and thought it was both meaningful and funny to play with the words soul and sole.

Yes, it’s perfect!

Make a Shoelace Manifesto

If you need a little kick-start, start here:

Ask: What are you curious about?
Try to limit the beads on each shoe to six, although seven could work. “Reading” is seven letters, and barely fit on a size 3 kids’ shoe.
Use these beads. Heads up: Some packages don’t come with even quantities of letters, so it’s best if you can see the beads in person.
Try one of these affirmations, or use these as a point of inspiration:
1. Smart – Cookie
2. Kind – Kid
3. Dream – Big
4. I am – Strong
5. Cre -ative
6. Posi – tive
7. I am – Loved
8. I am – Kind
9. Good – Human
10. I ❤️ – Myself
11. I ❤️ – Soccer
12. I ❤️ – Dance (etc.)
Take a photo of your shoes and tag it with #shoelacemanifesto

Engineering Kids | Rube Goldberg Machine

By Rachelle

Build a Rube Goldberg Machine with Kids

So, are you interested in building a Rube Goldberg-style machine with little kids? This post will give you a few tips and ideas to make your own complicated machine.

This project has long been on my to-do list with my kids. We are long-time fans of marble runs (see the resources page for recommendations), and extending our love for rolling balls and ramps into the world of Rube Goldberg was a no-brainer. And triple hurrah for projects that celebrate STEM and STEAM learning. We were on the hunt for easy Rube Goldberg ideas, watched a few videos, and came up with this fun solution that works for young children.

About Rube Goldberg

For the uninitiated, Rube Goldberg was an American Pulitzer Prize winning cartoonist, sculptor, author, engineer, and inventor, and his work is a classic example of the melding of art and science. Goldberg began his career as an engineer, and later became a cartoonist who drew elaborate illustrations of contraptions made up of pulleys, cups, birds, balloons, and watering cans that were designed to solve a simple task such as opening a window or setting an alarm clock. Interestingly, Goldberg only drew the pictures, and never built any of his inventions. However, these pictures have since served as inspiration for makers and builders who want the challenge of making wild inventions to solve everyday problems.

And apparently, Rube Goldberg is a now an adjective in the dictionary! You can read more about Goldberg here.

Step 1: Get Inspired

First things first, you’ll want to watch some Rube Goldberg contraptions in action to get inspired. My kids and I LOVE this video from OK Go. It’s incredible complicated, but oh-so-amazing, so don’t think for one hot second that you’ll be able to replicate this with little kids.

Step 2: Solve a Problem

Next, come up with a simple problem that you’re trying to solve. For example:

Ring a Bell
Pop a Balloon
Open a Door
Shut a window
Put out a candle

Once you have a problem sorted out (and don’t worry – you can change this later if you want), gather supplies…

Step 3: Gather Supplies

You can print out the following list here.

Collect a bucket-full of supplies and then lay them out so they’re easily seen. These can largely be found in your home or classroom — start with what you have! You will most likely start with some of these basics, and then forage your home or classroom for more supplies as you go. Here are some ideas to get you started:

Things that Roll

Marbles
Balls: Tennis, Baseball, Bowling, etc.
Toy Cars
Dominoes
Skateboard
Roller Skate
Mousetrap

Things that Move

Mousetrap
Dominoes
Toaster
Fan

Ramps

Toy Train Tracks
Marble Runs
Books
Trays
PVC pipe
Plastic tubing
Gutters

Recyclables

Cardboard
Cereal Boxes
Cardboard Rolls
Plastic Water Bottles
Cans
Aluminum Foil

Household Materials

Chopsticks
Popsicle Sticks
Ruler
Wooden Blocks
Bowl
String
Tape
Sand
Pins
Hammer
Balloons
Water
Fan
Vinegar and Baking Soda

Step 4: Build Your Machine!

Once you have the supplies ready, start building. While the OK Go video (and others like it) includes some pretty complex machines and concepts, keep this simple for preschoolers. The basic concept that we’re exploring is that of a chain reaction, so anything that tips something else over (and so one) is what you’re going for. Don’t worry too much about building things like pulleys and levers for young children.

Take a look at our machine to get a sense of what’s possible.

5 Tips for Success

Success breeds enthusiasm, so keep the steps to a minimum. You can always add more as you go.
Keep your expectations low
Ask your child for ideas and input
Work collaboratively
Aim to have fun

A Note on Failure

As you test and try out different set-ups, you’ll undoubtedly fail a few times. I could have filled a 20 minute video with outtakes from all our misses (the balloon is a good example of that). But this is great news! Failure is an intrinsic piece of the invention process, and without these mistakes we won’t learn how things really work. So embrace failure and celebrate it as part of the learning process.

Next Steps: Full STEAM Ahead

Ask: What other simple problems could we solve?
Ask: What materials could we use?
Ask: Why didn’t that work? How could we fix it or try it again?
Encourage your child to problem solve by seeking out materials and moving objects.

Activate Learning with STEAM

If you’ve been a loyal TinkerLab fan (thank you! you mean the world to me.) you’ll know that I’m happiest sharing projects that live at the intersection of disciplines. Too often we’re quick to separate science from writing or math from art, but when we seek out ways to make interdisciplinary connections, learning can be more meaningful and novel discoveries can be made.

In that vein, over the next few weeks I’m joining a creative group of engineers, scientists, educators, and artists to launch a new series called STEAM Power, which celebrates interdisciplinary learning with projects that circle around STEAM (science, technology, engineering, art, and math) ideas. This week’s theme is REACT, and you can see the other reaction-related ideas here:
