Complete the following assignment based on the above simulation
Learning Goals: Students will be able on a molecular level to
- Explain why a rigid sphere would float or sink.
- Determine what causes helium balloon to rise up or fall down in the box.
- Describe the differences between the hot air balloon, rigid sphere, and helium balloon.
- Explain why a hot air balloon has a heater.
Directions:
- Make sure that you put some gas in the sphere, balloons, and container so that you are representing real situations.
- Don’t vary the gravity for this activity.
- For each learning goal, do experiments and then use specific examples to write in paragraph form with illustrations explanations to demonstrate the goal. Include data to support your ideas.
