- The activity requires a Fizz Keeper pump cap to add pressure to the soda bottle
Pros
- Makes clear connections between pressure and geographical features to give students a clear picture of why winds move and change
- The teacher's guide includes tips for turning the demonstration into small-group experiments
Cons
- None
