I have known about using red cabbage as a color-changing acid base indicator for years. However, this experiment always seemed like too much work. Who has time to boil cabbage? It turns out ME during quarantine, that's who. I cannot believe how easy this red cabbage acid/base experiment was to put ...

This upcoming school year, my kids and I will be learning chemistry. I decided to start the year with this fun and easy spinach chromatography experiment inspired by the book Fizz, Bubble, and Flash! Element Explorations and Atom Adventures for Hands-On Science Fun! My kids learned that even ...
Super Easy Bottle Rocket

This has to be one of the most fun science activities I've done with my kids in a long time. It is super simple, inexpensive, and quick. It took us a few tries experimenting with how to add the baking soda to the bottle, but I think we got it down. We were able to make this super easy bottle rocket ...
Plant and Animal Cell Comparison Activity

If you happen to have already made a plant cell model and an animal cell model, comparing these two different types of cells is a natural extension activity. I actually recommend making these cell models simultaneously as they have almost the same list of ingredients. Thankfully, doubling the number ...
Plant Cell Model

A few weeks ago I published a post on how my family made an animal cell model. We actually made a plant cell model the same day. Plant and animal cells are very similar. There are a few key differences, however. I'm planning to do a post soon explaining how you can use these models to explain these ...
Animal Cell Model

Cell biology can be hard. Cells are too small to see and the science contains a lot of long, complicated words. How is anyone supposed to remember ANYTHING having to do with cells, when there's nothing to visualize? I'm hoping this animal cell model activity will solve that problem. (I've also made ...
Spotting the International Space Station

I LOVE astronomy. It all started when my mom rented me Space Camp from our local video store about 30 years ago. I became absolutely obsessed with that movie. As a junior in high school, I figured out how to enroll in our local community college so I could take Intro to Astronomy over the summer. ...
Cloud in a Jar Experiment

For the past several months, my kids and I have been studying Earth Science using the Sassafras Science Adventures curriculum. (My kids still enjoy this curriculum after 2 full years. Click here for my full unsponsored review.) However, as the school year draws to a close, we've definitely fallen ...
Color-Changing Invisible Ink

What better way to get kids excited about science than with an experiment straight out of a spy novel? Write a secret message using colorless ink, wait for it to dry, then use a special secret solution to reveal the message. This activity was inspired by the Berlin blue experiment in this chemistry ...
Extracting DNA from a Strawberry

Extracting DNA in the kitchen? I know what you're thinking. That *sounds* cool, but I'm sure it's way too complicated. At least, that's what I thought. I'd seen some instructions in the past that involved weird ingredients and lots of waiting and I figured, my kids won't be up for that. Then we did ...
