Introduction

Ask your child where heat comes from and what makes the weather warm. Explain that all of our heat comes from the Sun's energy. The Sun is millions of miles away, but its energy passes through space to reach us eight minutes later. Some of that energy we see as light, but a lot of it we cannot see. When the Sun's energy is absorbed by the Earth, it warms the Earth.

Reminder:

  1. Fill out your weather log each day as outlined in Lesson 1.
  2. Record the air pressure as outlined in Lesson 2.
