Discussion questions
Talk about it
Animals take in information through their senses and change their behavior with practice. Watch how the squirrels learn the course faster over the weeks.
- What senses do the squirrels use to work out each obstacle?
- How did the squirrels' behavior change from the first try to the last? What does that tell us about learning?
- If you were designing an obstacle, what would make it hard for a squirrel but fair?
Quick work-a-long
Vocabulary: adaptation, behavior, senses, problem-solving.
Try it: Watch one obstacle twice. Write down what the squirrel tried first, and what it changed the second time. Name the sense it relied on most.
