The two activities included in this guide introduce students to the principles behind Newton's Law of Gravitation. The guide provides teachers with background information, preparation suggestions for each activity, as well as material lists, and... (View More)

This educational wallsheet provides several simple illustrations of Newton's Second Law. In the activity included, students study the motion shown in the drawings to decide how it relates to the object's velocity, whether or not the velocity is... (View More)

In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies. This activity is part of the "Cosmic Questions" educator's guide that was developed to... (View More)

Students determine the moisture content of a sponge after squeezing the water out of the sponge, and allowing water to evaporate from the sponge. Students also measure the amount of water that has evaporated from the soil samples. This learning... (View More)

This is a lesson where learners explore how the creation and destruction of ozone protects us from ultraviolet radiation (UV). Learners will kinesthetically model the depletion of ozone caused by chlorofluorocarbon (CFC) molecules; use ultraviolet... (View More)

This is a lesson about radiation and the use of the scientific method to solve problems of too much radiation. Learners will build snow goggles similar to those used by the Inuit (designed to block unwanted light, while increasing the viewer's... (View More)

A simple experimental apparatus made of rubber band and books is used by student teams challenged with demonstrating the concepts of friction, force, and inertia. This resource is from PUMAS - Practical Uses of Math and Science - a collection of... (View More)

Using a paper and tape device, students experience how atoms and molecules of gas in Earth’s atmosphere absorb electromagnetic energy through resonance. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background... (View More)

Thermal images of Earth allow for the visualization and analysis of temperature differences. With the aid of ATLAS thermal images of a shopping mall in Huntsville, Alabama, students examine the impact of the addition of buildings and the loss of... (View More)
