- Practical exercise 1 Making models of the objects of the Solar System
- Practical exercise 2 Model the motion of Earth around the Sun
- Practical exercise 3 What are the distances of planets from the Sun?
- Practical exercise 4 What are the planets’ sizes?
- Practical exercise 5 When observing from Earth, why can we see the tilting of Saturn’s rings?
- Practical exercise 6 Model the motion of Uranus around the Sun and describe how seasons change for var-ious hypothetical positions of an observer on the „surface“ of Uranus.
Practical exercise 4: What are the planets’ sizes?
Aids:
• models of the Sun and planets (see section a), calculator, charts, chalk
Instructions:
1. You can use the practical exercise from section b) in this section as well.
2. Take the model of Jupiter as the basis.
• Calculate how big would be the models of other planets and the Sun.
• Try to compare what spherical objects would have the size which you have calculated; what would be the correct models instead of table tennis balls?
• Now calculate what would be the distances of individual planets from the Sun in this model.
