Fracture Fundamentals: A Cheesy Analog part of Examples
This activity has students make small cuts in processed cheese food and then apply shear stress perpendicular or parallel to the cuts to see what sort of fracturing will occur.
Half Life Model part of Examples
While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend the nature of half life. Students use the model to simulate the decay of radionuclides. The ...
Using Melting Ice to Teach Radiometric Dating part of Quantitative Skills:Activity Collection
Students are challenged to a Sherlock Holmes-style mystery in which they construct their own decay curves of melting ice to determine time-zero.
Demonstration of radioactive decay using pennies part of Quantitative Skills:Activity Collection
