Where Are the Cities?

This investigation requires students to locate several major U.S. cities using four different sources: an outline map, a nighttime lights image, an atlas map, and a space shuttle image.

Is Life On Mars Possible and Could Humans Establish Settlements There?

Searching the six satellite images of Mars provided in this investigation, students identify and locate areas that possibly sustained life in the past, might now sustain life, or could in the future.

Estimating Star Brightness

This is an activity about how we measure the brightness of stars in the night sky. Learners will use interpolation to determine brightness, then observe the brightness of Delta Cephei over the course of two weeks, and plot their observations as a light curve.

Water Wonders

Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates in an aquarium in their classroom.

Base-Two Slide Rule

In this activity, students construct base-two slide rules that add and subtract base-2 exponents (log distances), in order to multiply and divide corresponding powers of two.

Applications of Percents

Students will learn about NASA's Fermi satellite and gamma ray sources through reading a NASA press release. They will also learn about gamma rays and the electromagnetic spectrum by viewing a NASA eClips™ video segment.

MY NASA DATA: Convection Activity

This activity provides a visual example of convection in fluids. Students will record their predictions and observations on diagrams of the experimental set-up showing convection currents. Materials required include hot and cold colored water, thermometers, stopwatch, and index cards.

Invisible Light Sources and Detectors

In this activity, learners use visible light, radios, infrared remotes, heat lamps, and black lights (ultraviolet) to identify detectors of these sources as well as materials that transmit or block the energy.

The Pull of the Planets

Learners will model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it has on the surrounding space.

Domino Multiple Game

One particular type of domino game, sometimes called the All Fives Domino game, uses multiples of five in order to score points.
