First graders discover plate tectonics. They observe the forces of erosion. They observe the forces of weathering. They state three ways the earth changes. They record observations and make conclusions about their observations.

Young scholars complete research and solve problems that show the factors that determine the temperature of the earth's surface including the effect of greenhouse gases. They look at the relationships between solar energy, atmosphere,...

Students identify and explain that remote sensing can detect changes on the Earth's surface that occur over time, and name at least three: urbanization, deforestation, and succession. They select a global change issue to investigate and...

Young scholars research Earth including what makes it suitable for life, its rotation, geological composition and gravity.

First graders identify and explore the four inner planets. For this planet science lesson, 1st graders watch a PowerPoint about the planets. Students read the book Our Solar System and discuss the inner planets. Students create a book...

Students explore the Earth and its rotation. Volunteers model the sun-Earth system to demonstrate that the Earth rotates around the sun. In groups, students simulate "traveling" around the sun and discuss when it is night and day.

Students develop a sense of geologic ("deep") time and the ways in which Earth scientists construct the geologic time scale. They study he major events that shaped Earth, including the origin and evolution of its lithosphere, atmosphere,...

Students research the four geologic eras of Earth's history. In this extension on a fossils lesson, students research the different eras of Earth's history. Students use AppleWorks to create a bar graph containing information of the four...

Students compare natural and human made items and gain an awareness of the importance of Mother Earth to the Nez Perce people.

Students explore how the angle of sunlight affects the Earth's temperature and seasons and then apply this understanding to their local situation.

Students explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...

Students visualize the Earth's ecosystem at a specific time period and how Earth has changed over time. They create a detailed journal entry for a specific time period and create a birthday card to Earth.

Students work in cooperative learning groups to create PowerPoint or KeyNote presentations on how humans impact the earth. This lesson can be accomplished in three different parts.

Students participate in a JAVA activity to vary the seismic P and S wave velocity through each of four concentric regions of Earth. They match "data" for travel times vs. angular distance around Earth's surface from the source to detector.

Students analyze the factors that affect exploration such as religion, trade, territorial expansion, and science. In this Great Explorations lesson, students determine the names of famous explorers as well as their routes and...

Students explore the relative sizes of the Sun, Earth and Moon as they make an impressive large-scale model for classroom use throughout the unit.
