Hot-Air Balloon Design

Hot-Air Balloon Design

Introduction

Work in teams to design an experiment that will help show that hot-air balloons really can be used to transport people or animals in a safe way. Answer the questions below as you go along.


Question
What do you want to find out?

 

Hypothesis
What do you think will happen?

 

Procedure
How will you test your hypothesis? Write the steps for the experiment and address safety rules.

 

Materials
What materials will you and your team members choose for your experiment?


Data
Follow the steps in your procedure to perform your experiment. Record data and observations!

Assessment

What is air made of?

 

Draw a picture of the air inside your balloon at the beginning of the experiment.

 

 

 

 

 

Draw a picture of the air inside your balloon as it was rising.

 

 

 

 

Describe why heat was needed for the air inside the balloon.

 

How far were you able to transport your “passenger” in your hot-air balloon?

 

How long was your balloon in the air?

 

How might you be able to make your balloon go farther? Go higher?

 

Describe two ways that your experiment is “risky” or “potentially catastrophic” for transporting humans or animals.
