Students build a scaled model of the solar system. In this space science lesson, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative gravity.

Agriculture, deforestation, and urbanization. How have human's changed the planet and how might we mitigate the effects of human activity on the planet? To answer these questions class members research the changes in human land use from...

Class members learn how to estimate the total costs involved to design and build a bridge by including design, material, equipment, and labor costs. The activity includes a discussion about the trade-off between cost and aesthetics.

Students explore the Cambrian explosion and Paleocene extinction events. In this climate change instructional activity, students read articles to link evidence they find to extinction and climate change.  Links to the articles are...

Students examine trees and discuss how the environment effected the tree. They also predict what the area look like in fifty years.

Gain skills in ecosystem evaluation including chemical, biological, and physical qualities. Students write a report on a local ecosystem.

Students examine websites about mammoths that lived until the end of the Ice Age. They explore the woolly, Columbian, and the Jefferson's mammoth. There are printable sheets, illustrations, maps, and an animated movie showing mammoths...

Learners work together to construct a model of a water catchment basin. They survey water patterns and complete experiments to see where rain travels and collects. They discover how engineers design structures that help with drainage.

Students describe the overall events that occurred during the Paleocene extinction event as well as the processes that are believed to result in global warming after group research. They infer how a global warming event could have...

In this learning activity, students use a web-based geologic timeline to examine temperature, CO2 concentration, and ice cover data to investigate how climate has changed during the last 715 million years. Students will gain an...

A slideshow for teachers and students exploring Earth's geologic timeline and history. Click the buttons at left to select the teacher or student version.

Take this online quiz and test your knowledge of geological history, and the formation of our atmosphere, water, crust, oxygen, tectonic plates, Moon, and the rest of the Earth.

Appreciate the immensity of geologic time by scrolling through a timeline. Includes links to relevant portions of a video lecture and a detailed time line.

Here is an excellent example of a picture timeline. Follow the Eras of the Earth from Cenozoic all the way down to Precambrian with the use of fossils.

600 Million Years is a permanent exhibition at the Melbourne Museum that examines how Australia evolved through the geological ages, and the dinosaurs and other prehistoric life that lived in the Victoria area in the distant past. The...

Explore geologic time of the Earth and learn how radioactive decay helps to establish a timeline.

A lesson plan containing two activities for middle schoolers to gain a better understanding of geologic time scale. The first activity allows students to get a visual of geologic time by role playing events in time on a football field....

[Free Registration/Login may be required to access all resource tools.] For life to evolve from simple single-celled organisms to many millions of species of prokaryotic species to simple eukaryotic species to all the protists, fungi,...

Use this activity to help students understand the history of Earth by creating their own timeline of their life. By creating their timeline, students can see the resemblance and make connections between Earth's history and their own....

Understand the history of the Earth through geologic time.

Provides an overview of the Mesozoic Era, its time frame, geological and tectonic activities, the climate, plants and animals, and extinction events towards the end of this era.

This 2-page handout provides short descriptions of the different aeons, eras, and periods in the Earth's geological history.

Offers an easy to understand explanation of the earth's layers and the fossils we find in each layer. It explains how these are interpreted by scientists to represent the evolution of animal and plant life through the geological eras.

Take a look at this snapshot in time of Earth's history. This interactive timeline shows a unique perspective of where we are in historical and geologic time.
