Instructional Ideas

  • Make the opening discussion of wind and weather more relevant by including local geography and how it affects conditions in your area
  • Ask pupils to hypothesize how using a bigger bottle would affect the demonstration
Classroom Considerations

  • Use marshmallows, rather than Styrofoam peanuts, for an eco-friendly lab
  • 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
