Viscous Fluids
Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic, and...
Curated OER
Stress and Strain
Students use working models to show the stress and strain in the movements in the earth's crust. In this stress lesson students complete a lab in which they construct a model.
Curated OER
Forces Inside the Earth
In this faults activity, students identify the three types of faults and the characteristics that define a normal fault, reverse fault, and a strike-slip fault. This activity has 3 fill in the blank and 3 short answer questions.
Curated OER
Seismic waves
Learners discover the differences between P- and S-waves using a slinky. They see that when displacement occurs along a fault, the built up strain of energy is released in the form of seismic waves.
Curated OER
Building Bridges
Students, in groups, design and test a scale bridge. They use the Internet to research three basic bridge designs -- beam, arch, and suspension -- and the forces that act upon them.
Curated OER
Changing Crust
In this changing crust worksheet, students use candy bars, licorice sticks and bubble gum to simulate the 3 types of forces that change the Earth's crust. These include compressional forces, tensional forces and transversal forces. The...
Curated OER
Design & Technology: Materials Strength
Students investigate the function of a floor stretcher and some of the past designs. The goal is to improve the design durability and ease of use. Then they sketch their ideas and write a rationale for changes made to the structure.
