Hatching new scientists every day!

Share the Day’s Discoveries

Review today’s explorations and ideas about ramps. 

Using any photos, videos, and notes from the day, as well as a few foam tubes for demonstration, ask children about their experiences with flexible tubes.

  • What are some of the things flexible tubes can do?
  • How are they like cardboard tubes? How are they different?

Have children describe their roller coasters and how they created their hill. 

  • What was the highest and steepest point of your roller coaster?
  • How did having a high or a steep part of the track help with building your hill?

Ask children about testing.

  • How did you test whether your roller coaster worked?
  • How did testing help you change your roller coaster so it worked better?
