Students create a model of an aquifer and describe how an aquifer works. They describe how running affects an aquifer and prepare a model presenting to local planners the important aspects of protecting recharge areas.

students participate in hands-on activities to discover the different types of fossils. Using teacher-provided materials, they make models of cast and trace fossils. After writing essays describing how traces are formed, students plan a...

Site provides a detailed overview of crinoids, more commonly referred to as "sea lilies" and "feather stars." Content includes a focus on the animal's endoskeleton, feeding, commensalism, habitat, value, forms, and more. Also has great...

When an earthquake occurs, seismic shock waves travel out through the earth from the source of the event. The shock waves travel through the earth (body waves), or along the Earth's surface (surface waves), and can be recorded at remote...

Observe different forms of water and how it covers about 75 percent of Earth's surface in this media gallery captured by NASA and the U.S. Geological Survey (USGS). Use the satellite and ground images in this resource to enhance student...

This lesson introduces the concepts of wavelength and amplitude in transverse waves. In the associated activity, students will use ropes and their bodies to investigate different wavelengths and amplitudes.

Understanding Evolution provides evidence for evolution using fossils. There are also links to lesson plans.

Purdue University provides a great lesson plan for learning about the Earth's interior structure. Focuses on the crust, mantle and core. Also includes examples and great charts that students will enjoy looking at.

This is a lesson designed by a biology teacher. In it, students use maps and evidence of island age, molecular genetics, morphology, and distance apart to determine how the islands came to be occupied by different species of lizards. It...

Students hear a story as they "find" bones that you have put in an envelope for them. Their job is to begin assembling the bones as best they can. The students will invariably come up with different configurations--just like scientists...

These pages are part of a site called "Evolution," that accompanies a textbook by the same name. Mark Ridley is the author. These pages are about the house sparrow and the differences that can be observed in it in different geographical...
