I don’t know if there’s much that’s symbolic of fall and back to school time like apples, so let’s play with our food and do some learning while we’re at it with these apple STEM and STEAM activities.
Why not make an apple bird feeder and keep a log of the different kinds of birds and other animals you see using it? Messy Little Monster has this simple DIY.
Since apples are alive they can decay, so you can use them to learn about mold (on a smaller scale than the classic decaying pumpkin experiment). Share It Science has a post about a kid’s book you can read about observing mold and decay, plus all the details for setting up your own kid-led experiment to see what happens when apple slices are left to rot and how well different preservatives help them stay fresh.
On the other end of the spectrum you can dry apples, which is another means of preserving them. Adventure in a Box has all the details for turning apple drying into a science experiment for kids that you can eat when it’s done!
While you’re slicing apples, make some apple boats with this idea from A Dab of Glue Will Do. Let the kids decorate their sails (and/or make them different shapes, sizes and materials) and have them use the worksheet in the post to hypothesize whether their boats will float and why.
Kid Minds has a fun experiment using an apple where you investigate the center of gravity by balancing an apple off the edge of a table. Head to the post to see how and why this one works (and definitely consider doing the stabbing of the apple yourself instead of having a kid do it).
And then of course there’s the classic apple volcano experiment, speaking of things done on a smaller scale than using a pumpkin. Homeschool Preschool has all the details on this fun project that kids of all ages enjoy.
