Lunar & Asteroid Traveling Exhibits

This collection of nine portable traveling exhibits communicates different aspects of lunar and asteroid science and exploration. Developed for use in public libraries and informal education settings, each exhibit consists of three banners with accompanying stands, and telescoping poles.

Climate Kids: Make Sun S'mores

Instructions are provided for making a solar oven, followed by directions for using the oven to make s'mores. A side column discusses the practicality of using solar ovens in places like western Africa.

Marvelous Martian Mineralogy

This is a lesson about determining planetary composition. Learners will use a reflectometer to determine which minerals are present (from a set of knowns) in a sample of Mars soil simulant.

What are Magnetic Fields?

This is an activity about magnetic fields. Using iron filings, learners will observe magnets in various arrangements to investigate the magnetic field lines of force. This information is then related to magnetic loops on the Sun's surface and the magnetic field of the Earth.

Inverse Functions

In this activity students use log tapes and base-two slide rules as references to graph exponential functions and log functions in base-10 and base-2. Students discover that exponential and log functions are inverse, reflecting across the y = x axis as mirror images.

Anatomy of a Black Hole

This interactive, online module provides an introduction to the concept of a black hole. Students explore the components of a black hole by using a diagram of an accretion disk, an event horizon, and jets of hot gas. Students may complete this activity independently or in small groups.

Did Impacts Create Features on Mars?

Learners will use trays of sand and a variety of solid objects to model the effects of "impactors" on the surface. This is activity 6 of 9 in Mars and Earth: Science Learning Activities for After School. <b>Note: The Mars image set that is needed to do this activity is on p.

Star Witness News: Asteroid with Six Comet-like Tails Surprises Astronomers

This science news story highlights a Hubble Space Telescope observation of an unusual asteroid. Astronomers hypothesize that the spin rate of the asteroid increased to such an extent that materials were flung off its surface.

The Heliosphere

This lithograph outlines the components of our heliosphere, using current information released by the Interstellar Boundary Explorer, or IBEX, spacecraft team.

MRC: Brainstorm and Preliminary Design (Grades 3-5)

Learners will become familiar with and use the engineering design process to sketch a reasonable drawing of the rover that will be built.
