Questions:
1. Which side will the see-saw tilt toward first?
2. Which side will the see-saw tilt toward at the end?
Answer
1. The see-saw will tilt toward the basketball first after the ice has melted a bit. The water won't be able to stay on the see-saw, so that side's lighter.2. The see-saw will balance out in the end, because the basketball will roll off after it tilts towards it, and the ice will melt entirely and the water will run off and/or evaporate. So there will be nothing on the see-saw at the end.
