Assessment & Evaluation

Young scientists use a instructional activity to help them perform a lab on the decay of a radioactive element. The instructional activity serves as both a task guide and a lab sheet for pairs of learners. This activity requires a...

According to Einstein's Theory of Special Relativity, time moves slower when you're working. That's not quite what it says, and in a hands-on lesson, pupils learn the actual theory. Scholars plot the half life of muons, then compare it...

Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...

In this math/science worksheet, students will work in pairs to conduct an experiment based on a decay function which is often used to model radioactive decay. Students will shake M & M's in a cup to rub off the M and then record...

There are no tricks here! Young scholars learn about the concept of centripetal acceleration by studying the design of the snowboarding half pipe. A video lesson describes how the half pipe design affects the motion of the boarders.

[Free Registration/Login may be required to access all resource tools.] The half-life of a radioisotope, rates of radioactive decay and variation in half-lives in different radioisotopes.

There are different types of radioactive decay, and alpha decay is when there are too many protons in a nucleus. Here is a simulation that shows alpha particles being emitted from a polonium nucleus. Learners see how radioactive decay...

In this activity, students gain a better understanding of radioactive dating and half-lives by using M&Ms to demonstrate the idea of radioactive decay. They will be able to see how scientists can determine the age of rocks by looking...

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
