Cuarto: Matter 2

Remember Matter can be measured by mass (the amount of matter in an object) and volume (how much space an object occupies). 

However, Matter can be in three states: Liquid, Solid and Gas. Watch the video below to review mass and volume and to learn about liquids, solids and gases.

Now we are going to do an experiment with liquids and solids. Follow the directions below and you will have a treat for this warm weather!

Ingredients:

• Can of frozen orange juice
• Pitcher
• Large spoon
• Water
• Paper cups or glass cups
• Wooden craft sticks

Directions:

Step 1: Fill several paper cups about 2/3 of the way with orange juice.

Step 2: Put a craft stick into the liquid in each paper cup.

Step 3: Being careful not to spill, put the cups of juice into the freezer.

Step 4: 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 5: Once the orange juice has frozen, peel off the paper cups. You and your friends can enjoy a frozen treat!
