Discussion questions

Talk about it

A kangaroo rat survives with two tools: spring-loaded back legs for an instant jump, and big ears that catch the faint sound of a snake. Sensing danger and reacting fast keep it alive.

  1. What two things about a kangaroo rat help it escape a snake?
  2. How do its big ears give it an early warning?
  3. Why must the jump happen so fast to work?
