This 4th grade Science lesson was shared with us by the International School of Louisiana.
Materials (for 6 small groups):
- 6 cleaned, recycled plastic soda bottles with 1/4" holes drilled in the cap and the bottom
- 6 wooden dowels (¼ " diameter and long than the length of the soda bottle)
- 6 rolls of duct tape (one for each group)
- 1 roll of string (shared between all groups)
- 1 box of popsicle sticks for turbine fins (or index cards covered in plastic wrap)
- 6 stopwatches
- tap water and drain access
