Teaching Tip:

Earth’s HeaterOn a sunny day, take the class outdoors early in the morning. Invite children to feel the soil, rocks, concrete in the schoolyard, and the wall of the school itself. Do they feel warm or cool? You may even have them record the temperature outside. Repeat the activity later in the afternoon. Ask: Do the objects feel warmer in the morning or in the afternoon? After rereading their books, challenge students to explain what is warming the objects and how those warmed objects affect the air that touches them!
