Each science class, we have been studying how the forces of gravity, lift, drag, and thrust effect flight. Today we extended our learning to understand how hotair balloons fly. We worked on an experiment as a whole class. A kitchen garbage bag simulated the envelope of a hot air balloon, and a hair dryer simulated the hot flame...
By combining the information gathered from conducting the experiment and watching an informational video on hotair balloons, the students came to some conclusions...
1. The larger the envelope, the more weight can be carried.
2. The hotter the gas, the higher you will fly.
3. Weather has a huge impact on drag and thrust and is important for directing travel.
