• Use extend portion as homework

Classroom Considerations

• Materials needed are easy to gather and should be found in most science classrooms, with exception of candy
• Part six in a series of nine
• Lesson connects to the previous lesson in the unit

Pros

• Activity is set up in the 5E format
• Teachers have access to reference materials, activity sheets and keys, and reading passages

Cons
