Solid to Liquid to Solid
Watch the transition from solid to liquid to solid in this science project for kids on states of matter -- and make something good to eat. Solids can change into liquids, and liquids can change into solids. Make ice pops with orange juice, and you can see both transformations.
What You'll Need:
- Can of frozen orange juice
- Large spoon
- Paper cups
- Wooden craft sticks
Step 1: Open a can of frozen orange juice, and spoon it into a large pitcher. Touch the frozen juice to feel that it is both solid and cold.
Step 2: Add water according to the package directions to make orange juice.
Step 3: Fill several paper cups about 2/3 of the way with orange juice.
Step 4: Put a craft stick into the liquid in each paper cup.
Step 5: Being careful not to spill, put the cups of juice into the freezer.
Step 6: Check them after two hours. Can you gently pull out the craft stick, or has the liquid orange juice frozen solid around the stick?
Step 7: Once the orange juice has frozen, peel off the paper cups. You and your friends can enjoy a frozen treat!
