Curated OER
Determine Soil Particle Size
Students examine various soil samples in groups. Using the samples, they identify the characteristics of them and calculate percolation and infiltration rates. They use this information to discover why some species can survive in one...
Curated OER
Three-dimensional cooperative modeling
Students explore what is present below the surface in order to drill into the ground and record the type of material that the drill brings to the surface. They discuss the benefits and drawbacks of distance communications. Students...
Curated OER
Aquifers and Recharge Areas
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.
Curated OER
Science: Down Home Dinosaurs
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...
