The"Dirt" on Soil

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...

What's in soil? Young scientists study the pH levels of soil from their school yard. They observe the land and area the soil came from to decide if location has anything to do with acidity level.

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...

A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

Dirt is worthless, isn't it? Find out the true value of dirt, and by dirt I mean soil. The class explores what makes soil, the types of soil, and what happens when soil becomes void of its nutrients. There are several great activities,...

Students examine the basics about soil.  In this soil lesson students describe the physical properties of soil and explain what soil profile is. 

Students examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.
