In this lesson, your child will learn about wind and how to measure its speed and direction. He will also create his own weather vane. The first activity will introduce your child to the concept of wind.

Ask your child to describe a windy day. How does he know whether a day is windy or not? What might he observe on windy days?
  1. Fill out your weather log each day as outlined in Lesson 1.
  2. Record the air pressure as outlined in Lesson 2.
  3. Take four temperature readings during the day for the daily temperature experiment as outlined in Lesson 3.
