Why Are Days Longer in Summer?

Kids think there's nothing better than staying up late in the summer--there's no school to get to sleep for, it's warm, and the sun is out late. But why is that the case? In this fascinating volume for young readers, this question is answered in simple, clear terms. The main content discusses how Earth moves around the sun, Earth's tilt, and seasons, all in support of the elementary science curriculum. The achievable text supports knowledge building, a key component of the science of reading.
