Designing the balloon's structure, including the basket and burner systems, requires a strong understanding of mechanics and materials science.
Designing for lift and stability involves understanding aerodynamics and flight mechanics.
Creating the balloon's envelope requires knowledge of fabrics, their properties, and how they behave under stress.
Key Parts of a Hot Air Balloon:
Key Parts of a Hot Air Balloon:
Envelope: The large, fabric bag that traps the heated air.
Basket: The platform or frame that carries the pilot and passengers.
Burner: The device that heats the air inside the envelope, usually using propane or a similar fuel.
Gores: The panels of fabric that make up the envelope.
Crown Line: A rope attached to the top of the balloon, used to control inflation and deflation.
Drop Line: A rope connected to the basket, used to help the balloon land in a specific area.

Hot Air Balloon Challenge: Your challenge is to design a hot air balloon and test it to see what is your maximum height and time that you can keep your balloon in the air.
SMART Goal:
In the next 5 days, we will use tissue paper, glue and other materials to design and build a hot air balloon that will successfully hold hot air and launch.
Watch the video to learn how hot air balloons work and for directions on building your hot air balloon.
Testing
Testing
You will be using the Indoor Balloon Tester to launch and test your design.
Ask Mrs. Wilson for a Data sheet to keep track of your balloon launches.
Take a video of each launch and time how long your balloon stays in the air.
You will also take a video of yourselves talking about the results.
Here are some talking points to include:
Was your first launch successful? Describe what happened?
Did you have to make any improvements or fix anything between launches?
How long was your hot air balloon able to stay afloat?
Explain the science behind it? What makes the hot air balloon rise up in the air and stay up? Why does it eventually come back down?
