Earth Unit Overview

History of Earth

The Earth has changed since its beginning and continues to change today. Most of the changes on Earth happen over such a long period of time they cannot be observed. In this module students experience how the Earth has changed over time and learn about the clues that are used to identify those changes.

Materials

Everything is made up of different materials – even the Earth. Earth is made up of rock, water, and soil. This module provides students with the opportunity to explore Earth’s different materials and how living things utilize them.

Features

Mountains, canyons, lakes, and rivers are some of Earth’s features. Although they give shape to the surface of the Earth, over time the movement of wind and water causes these features to change. In this module, students discover how weathering and erosion change Earth’s features over time.

Weather

Whether rainy, sunny, cloudy, or windy, the weather describes what it’s like outside every day. Knowing the patterns of weather can help you to be prepared. In this module students explore the different types of weather and the tools needed to observe, measure and record it.
