Q: What can we notice about the motion of the marble on the roller coaster tube?
1. Explain: Share the concept of forces and motion using a United Streaming video clip or using a nonfiction text. I like to use snippets from United Streaming to show a real roller coaster in motion. The kids get a "Wow" factor and an immediate hook....
2. Label a diagram of a roller coaster to show:
*marble’s position (near the top, traveling down, etc…)
*force – push or pull (we use a push to start the marble, then gravity pulls it along)
*motion – how the marble moves (up, down, forward, backward)
This may seem "elementary" but many kids do not connect the science behind the "fun" until they draw it out on a diagram in their notebooks.
This student, on the other hand, uses the correct terms of motion as well as push and pull for force. She included a key with blue to show force and red to show motion. This shows me she is connecting the science terms to the activity.
