How Do You Measure Radon?

After reading a brief overview of automobile history and introduction to energy and motion, automotive engineering teams plan, construct, test, and evaluate a rubber-band-powered car. This manipulative experience can enrich understanding...

Lights, camera, action! Math educators consider how to improve their instruction by examining a model of the five-practice problem-solving model involving a movie theater. Participants examine cognitive demand in relation to problem...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...

You'll C-E-R a difference in classroom achievement after using a helpful lesson. Designed for economics, civics, government, and US history classes, participants practice using the CER model to craft arguments about primary and secondary...

Capillary action is the frugal chemist's dream ... the less liquid used, the more tests they can run! Learners experiment with the best design to maximize the benefits of capillary action. Using a liquid sample, they design a capillary...

Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.

Are video games sports? Pupils investigate this question as well as various nonfiction selections to learn more about claims and the support that defines them. All of the selections mimic the rigor on state tests and encourage close...

Young scholars exchange fake bodily fluids with other students. They track the spread of the "infection" throughout the population of young scholars and determine where the infection began in the class. Every student in the class...

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...
