Student Exploration: Coastal Winds and Clouds
Name: Ashrita Suram Date: 11 - 01 - 2020 
The air molecules inside heat up and they expand, as the air expands 
they become less dense than the surrounding outside air. This 
causes the balloon to fill up and to begin to float in the air. The more 
heat you add the lighter the balloon becomes. 
The air will cool, it becomes more dense, takes up less space, and 
the balloon will begin to sink in the air. 
1. Click Pause ( ) when the sailboat starts 
moving towards the shore. This represents
