What Causes Wind?

Lesson Plan

State Standards:

Explain how air, temperature, moisture, wind speed and direction, and precipitation make up the weather in a particular place and time.

Essential Question:

What causes wind?

Lesson Question:

Why is it hotter in your attic than in your basement?

Introduction:

In your groups, discuss in Claims Evidence format examples where you have seen heat rise.

Task:

You will perform an experiment that will demonstrate hot air rising. In this experiment you will place a tell tale, used in determining wind direction on sail boats, above a heat source and another tell tale not above a heat source and oberve what happens.

Lesson Experiences:

Make tell tails using tissue paper and yarn.

balloons

You will need two per group.
Both tell tales should be hung from the ceiling.
Place a light bulb under 1 of the tell tales.
Observe the tell tales above the light moving more than those not above the light bulb.

Conclusion:

This video demonstrates what you should have seen in your experiment.

Why does this happen?

Hot air balloon, density, convection

Assessments:

Create a glogster to demonstrate the motion of air molecules in a system with changing air temperature.
