Learners will use an inexpensive, simple spectrophotometer to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples. Clear water is used as the “control,”... (View More)

This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. This activity is scheduled to occur during Monday of... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction... (View More)

In this lesson, students explore the cosmic microwave background to understand why it permeates the universe and why it peaks as microwave radiation. Students should be able to explain that the origin of the background radiation is the uniform... (View More)

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets. The activity is from PUMAS -... (View More)

In this learning assessment, students demonstrate understanding of the following concepts: solids, liquids and gases, changes of state, convection, and density. Students create a skit where the actors and actresses are molecules, and dramatize,... (View More)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)
