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

• None
