This resource describes the physics behind the formation of clouds, and provides a demonstration of those principles using a beaker, ice, a match, hot water, and a laser pointer. This resource is from PUMAS - Practical Uses of Math and Science - a... (View More)

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

This experimental activity is designed to develop a basic understanding of the relationship between temperature and pressure and that a barometer can be constructed to detect this relationship. Resources needed to build a simple barometer include a... (View More)

In this demonstration, students detect the interference of waves and measure wave phenomena using an experimental apparatus consisting of a laser pointer, a second surface mirror scrap (like a bathroom mirror) binder clips, razor blade, ruler, and a... (View More)
