What causes the wind?

Time Required
3-4 class periods
Students will learn about the forces that cause wind and how to measure these changes in the atmosphere.


Students will dive into the reason that wind exists in this lesson. Through hands-on experiments that demonstrate how air pressure differences influence wind patterns, students gain a better understanding of wind and our ability to harness its power. Students will also build a barometer to learn about how we can measure aspects of the wind.
