Instructional Ideas

  • There is a great extension teachers may want to include in the activity; complete it before class to determine if pseudo explosion is messy or unsafe
Classroom Considerations

  • All materials should be found in a standard science classroom (with exception of M&M's)
  • Participants might want to eat the M&M's; be prepared to address whether they may eat the lab materials
  • Teachers may want to use smaller bottles of soda (less than 1-liter) for first portion of the lab in order to save money
  • Part eight in a series of nine
Pros

  • Activity uses the 5E format
  • Provides teacher references, activity sheet and key, and reading passage
  • Includes scripted critical thinking questions for teachers to use throughout the activity
Cons
