It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
Colors of Stars
Source Institutions
In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.
Build the Big Dipper
Source Institutions
Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.
LEGO Orrery
Source Institutions
Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.
Build Your Own Hydroelectric Generator
Source Institutions
Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.
Make Your Own Telescope
Source Institutions
Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.
Space Origami: Make Your Own Starshade
Source Institutions
In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
Does the Moon Rotate?
Source Institutions
This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
A Universe of Galaxies: How is the Universe Structured?
Source Institutions
This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.
Exploring Earth: Temperature Mapping
Source Institutions
This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
