The Gobstopper Experiment!
The Gobstopper Experiment is a good beginning of the year activity for middle school students to introduce the idea of the scientific method, steps of a science experiment, or anything related to scientific inquiry or thinking like a scientist.
In the past I have saved it for when we differentiate between a physical and chemical change in 7th grade chemistry units.
This experiment and investigation can be used in pairs or in groups. Materials list is included in the investigation procedures. Students will come away with a better idea of how to make observations in science and think like a scientist.
Thank you again for considering Middle School Scientists at Work!
