This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,... (View More)

Audience: Informal education

This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light... (View More)

This is a lesson about emission spectra. Learners will look at various light sources (including glow sticks and christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering... (View More)

In this lesson, students explore a discrepent event by designing experiments to test either what makes a "come-back can" return (a can that when you roll away from you, always returns) or UV beads change color. This activity should come either near... (View More)

Audience: High school
Materials Cost: $5 - $10 per group of students

In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (View More)

In this activity, students are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations... (View More)

The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda... (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)

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 basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials.... (View More)
