Investigation 4 – PostLab
If time permits, answer each question below.
Complete the Analysis Questions in your SDR then discuss them as a class.
Note: Questions marked with a triangle (∆) are included to enrich your understanding. These questions do not appear in your SDR but should be used as additional discussion points during the PostLab.
- ∆ What did the ping pong ball and each part of the flour model represent?
- ∆ What did the model with the scooter represent?
- ∆ What happened to the scooter when it was pushed in a straight line? Why?
- How does your drawing of the tape and string explain why the ping pong ball and the scooter continued in a straight line after the force of gravity was eliminated?
- Describe the path of the scooter when the Sun’s gravitational pull became much greater.
- In the Sun’s gravitational pull model, what does the quick pull of the rope represent?
- Why is the combination of forward motion and gravity important in maintaining the orbit of the planets and the Moon?
- ∆ What did you learn from the models of planets in their orbits?
- ∆ Why is gravity important in the orbits of planets and moons in our solar system?
- ∆ How does Newton’s First Law of Motion explain the orbit of planets or the Moon?
Complete the Focus Question in your SDR then discuss it as a class.
- What causes the orbit of the planets around the Sun and the Moon around the Earth? Why are they important in maintaining the orbit of the planets and the Moon?
The Comprehension Check is designed to summarize the CELL and provide the teacher with an informal way to assess your understanding of the big ideas of this CELL.
- What causes the seasons?
- What causes day and night?
- What causes the moon phases?
- What causes the orbit of the planets around the Sun and the Moon around the Earth?
- How are forces and changes in motion responsible for many of the phenomena we observe in our solar system?
