A Scientific Experiment with Celery and Food Coloring

The following post is from the archives. It originally appeared in April, 2011. While I’m an art educator by trade, having small people pulling at my pants has turned me into a mini-alchemist who’s suddenly found herself reading books to her kids about Galileo (The Magic Schoolbus and the Science Fair Expedition) and brewing [...]

Diet Coke Mentos Experiment

My 4-year old and our neighbor enjoyed witnessing this explosive soda and Minty Mentos experiment. Have you tried it? It doen’t require a huge set-up, and the show is pretty awesome. I have to warn you that the explosion itself goes by quickly, so you might want to have an arsenal of soda containers on [...]

Invisible Ink: A Citrus Painting Experiment

Can you tell me what you think? I’m playing around with my header design (procrastinating away from other important things, no doubt) and would love to hear your opinion on it. Do you like it? Is it legible? Does it need anything? What do you think about the sub-heading? When you think about Tinkerlab, what [...]

Egg Geodes Science Experiment

Today I’m excited to talk with you about a cool science experiment: egg geodes. Because children will engage in steps of the scientific method, this could easily be a great science fair project. I was inspired by these egg geodes that I spotted on Martha Stewart and then followed this recipe by Melissa Howard who blogs at Those [...]

Are Black Markers Really Black? A Chromatography Lesson.

What 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 [...]

How to…Invent a Recipe with Kids

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 [...]

Magical Plastic Bag Experiment

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 [...]

Is it Magnetic? Testing Objects for Magnetism.

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 [...]

Yeast and Sugar Experiment

I’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 [...]
