- Have individuals use different size droppers to see if their results change
- Discuss why the experiments use wax paper and if something else would work instead
- Assign the activity sheet for learners to complete as a class, in small groups, or individually
Classroom Considerations
- The first in a set of five lessons
- The activities would best fit as the first lesson in a chemistry class
Pros
- The resource is a 5E lesson plan design
- Materials are all readily available
- Provides activity sheets and extension ideas
Cons
- Over simplification of the big ideas can lead to confusion later
