Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?

Get your hands dirty with a set of earth science activities! Class members delve into a hard-boiled egg to find the similarities to the earth's layers, create a papier-mâché model of the earth, craft a simulation of the earth's...

It takes a strong foundation to build a house and a stronger one for a bridge. This resource presents the effects of geology and soil on bridge foundations. Working in groups, the class investigates the interaction of shallow and deep...

Soil scientists gain experience with an infiltrometer can to determine the infiltration rates at different locations on campus. If you are using the entire unit, the class has already analyzed water flow and soil types, so they should...

Maintaining a garden is an ongoing responsibility. This resource follows a series of activities in a unit that resulted in the planting of a rain garden. What you will find here are general instructions for watering, weeding, pruning,...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Young botanists examine the different parts of tress and then draw parallels between the functions of these parts and the function of parts of the human body. 

Students investigate the critical nature of foundations as they learn differences between shallow and deep foundations, including the concepts of bearing pressure and settlement. Using models representing a shallow foundation and a deep...

Students build a model to learn about the cycle of erosion and deposition by water and wind which deposits layer upon layer of rock, soil, and organic material to the surface.

Groundwater is stored in and moves slowly through layers of soil, sand and rocks called aquifers. To help you visualize groundwater, you will make an aquifer, in this case, an edible one. This will show you how groundwater is stored and...
