Moving Molecules
You need:
- 2 small balloons
- 2 large glass jars or glasses
- cold water
- warm water
Directions:
1. Fill each of the balloons with cold water and tie knots to secure the
water inside. Make sure the water is cold; you may need to chill the water
with ice cubes or in the fridge or freezer before the experiment.
2. Fill one of the jars about halfway with warm water.
3. Fill the other jar about halfway with cold water.
4. Place a water-filled balloon in each jar. What do you notice?
Explanation:
The balloon with the cold water sinks to the bottom of the jar because cold
water is heavier than warm water. The cold water is actually denser than
the warm water which means it has more mass for its volume.
