They were super fun to make, and kept my preschooler fully engaged for several days as we watched the crystals grow larger and larger every day. This is a super fun STEM lesson plan that you can use as one of your fall apple STEM activities.
Follow along to learn how to make your own salt crystal apples. This activity is perfect for toddlers, preschoolers, and older kids alike!
How to Make Homemade Salt Crystals that Look Like Apples!
We’ve always tried to give our kids educational activities and STEM activities to try, but my kids quickly got bored with repeating the same experiments over and over.
So this time, in celebration of the fall season, we made our homemade salt crystals look like delicious sparkly apples!

Salt Crystal Science for Kids
If you are making salt crystals, you might want to know the science behind it!
Salt crystals form when water evaporates from a supersaturated salt solution.
As water evaporates, it can’t hold on to as much salt. The salt deposits then cling together and form square crystal shapes.
In nature, you’ll see this happen near oceans, in salt caves, and in special saltwater pools like the Dead Sea.
Apple-Themed Teaching Resources
Apples and teaching go hand-in-hand!
Add these fun apple-themed teaching supplies to your classroom (or your house, if you just love apples that much!).
Because a lot of these natural salt formations aren’t made of pure salt, you won’t see the square shape of the crystal as much as with homemade salt crystals.
But when you look closely, you’ll see that salt always makes a square shape, unless it has something extra added like when growing crystals with bluing and ammonia!
And of course, you can also use this crystal activity when you’re looking for fun crystal experiments to try.
