All week, we’ve been exploring pressure at the bottom of the ocean. Now, what would happen to water in space where there is no gravity?
Space Balloons
Check out this video of water balloons in space:
Here are some suggestions for discussion topics (or worksheet questions):
1. How does popping a water balloon in space differ from popping one on Earth? How does the water behave differently? Why?
2. What forces act (or NOT act) on water in space and on Earth? Before you pop the balloon? After you pop the balloon?
3. What is holding the water together in space?
4. Why does the water not fall into small droplets in space like it does on Earth?
5. What do you think would happen if you popped a balloon filled with colored water underwater? What would happen to the water? Why? What forces would be acting on the water?
6. What factors are in place in the ocean that are not in place on land or in space that may affect the popping of a water balloon? (Currents, Fish, Salt, etc.)
How deep can they go?
Here’s an interactive website that shows how deep humans, ROVs and animals can dive.
