After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Students examine the similarities and differences between weathering and erosion. They participate in a lab in which they test the effects of different materials when exposed to weathering and erosion. They record their observations.

Just how powerful is erosion? Interested scientists learn how to identify the results of erosion with a series of lab activities. They move through stations to experiment with different types of erosion and then design and complete their...

Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

Mother Nature's Gravel Company is open for business! The unit includes four lessons covering weathering and erosion. Experiments are simple to complete and young geologists compare notes to see who makes the biggest ice...

Students investigate how natural selection influences evolution. They complete a hands-on lab simulation of natural selection, and replicate a real experiment and examine the interplay between selection factors in a population of guppies.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
