In the Deep Freeze easy science project, kids will discover how rocks break. Winter can be hard on everybody -- even on rocks. See how the cold affects more than just your toes with the Deep Freeze experiment.
What You'll Need:
- Small sealable plastic bag
How to Do Deep Freeze:
Step 1: Put an egg in a sealed plastic bag and put the bag in the freezer overnight.
Step 2: In the morning, see what the freezing temperature did to the egg. When the egg freezes, it expands and breaks its shell. Winter freezes do the same thing to rocks that have moisture in them. The moisture expands as it freezes, causing the rocks to break.
Step 3: When you're out walking in the winter, see if you can find rocks that have been in nature's deep freeze. A rock that is broken into pieces but still lying in its original shape is probably a victim of winter's icy strength.
Next, kids can learn how to read a weather map for an easy science project.
