Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Take your class of youngsters on a prehistoric adventure with this four-lesson series on dinosaurs. Accompanying the Meet the Dinosaurs books by Don Lessem, these lessons engage children in writing their own dinosaur books,...

By constructing a watershed model and identifying watershed features in it, they discover how water erosion changes the landscape. As with most watershed modeling activities, this one is costly in terms of time and materials. It is,...

A site devoted to fossils! Click on any of the main topics to access information regarding what fossils are, how they are formed, fossil collecting, student activities, fossil hunting, and even lesson plans.

[Free Registration/Login may be required to access all resource tools.] How scientists can learn information about the past from fossils.

A learning module where students tour the fossil record to learn what fossils are, how organisms become fossils, the factors that promote fossilization, how paleontologists find fossils, and why some organisms cannot be fossilized....

A suite of lessons lead inquiry-based exploration of melting sea ice and evidence that it is affecting sea level, namely glacial evidence, geologic evidence, fossil evidence, and isotopic evidence.

This interactive learning module will focus on the fundamentals of energy and energy sources, renewable and nonrenewable, that support the human population. Students will also explore our dependence on nonrenewable fossil fuels to...

For this lesson, students embark on an adventure to find out what life was like in Montana 60-70 million years ago. Students "join" a research lab to collect fossils from Montana and analyze them to find direct and indirect evidence of...

Click "Start Fieldtrip," for a wonderful look at a subject that has been a constant amazement to children of all ages. This dinosaur learning module for grades 1-3 is a "Prehistoric adventure," discussing dinosaur fossils, the size of...

In this interactive tutorial you will explore how geologists use clues in rocks to determine the order in which rocks formed. Learn how principles of radioactivity are used to assign actual ages to rocks. Students will explore fossils...

[Free Registration/Login may be required to access all resource tools.] How rock layers in different locations can be connected to make pictures of a region's geology.

[Free Registration/Login may be required to access all resource tools.] Looks at how stratigraphy can be used to determine the relative ages of rocks, how unconformities occur, ways to match rock layers in different areas, and how...

Through informational text, online lab activities, virtual simulations, and video clips, students study the concepts of biological evolution.

This site will explain how the Woolly Mammoth evolved, where it migrated and what is now being done to try and clone it.

In this comprehensive interactive tutorial you will learn how we can reduce our carbon footprint by using alternate energy sources.

The study of rocks is called petrology. Rocks may have fossils in them, and they are made up of minerals, but petrologists like looking at the rocks themselves. Just click on one of the link to find out more about rocks and the rock cycle.

Finding alternative energy sources is a challenge facing the leaders of today and tomorrow. Andy Darvill has created an impressive resource, summarizing various renewable and non-renewable energy resources.

In this amazing interactive tutorial you will learn about what methods are used by geologists to learn about the history of the Earth. Investigate a geologic time scale and learn about how scientists have developed and organized a record...
