Where is the Sun?
Source Institutions
In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.

The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

Where Are the Distant Worlds? Star Maps
Source Institutions
This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

Edible Model of the Sun
Source Institutions
In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.
Stories in the Sky
Source Institutions
In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

The Pulse of Gravity
Source Institutions
In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

Your Age on Other Worlds
Source Institutions
Did you know that you would be a different age if you lived on Mars? It's true!

Why Do Eclipses Happen?
Source Institutions
This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

Heavyweight Champion: Jupiter
Source Institutions
In this activity, learners confront their perceptions of gravity in the solar system.

Space Stations: Bones of Contention
Source Institutions
In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

Landing the Rover
Source Institutions
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.

Space Stations: Sponge Spool Spine
Source Institutions
In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Dry Ice Comet
Source Institutions
In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Shadow Dance
Source Institutions
In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

Make a Sun Clock: Tell Time with the Sun
Source Institutions
Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

Egg-cellent Landing
Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.
