Why Does the Moon Have Phases?
Source Institutions
In this activity, learners use a simple 3D model to discover why the Moon has phases.
Aerogel
Source Institutions
This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.
DIY Sunprints
Source Institutions
In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.
Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
Observing the Moon
Source Institutions
Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.
Weight in Space
Source Institutions
In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.
Hail Storm House
Source Institutions
In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.
Exploring the Universe: Static Electricity
Source Institutions
This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.
Molecules in Motion
Source Institutions
"Molecules in Motion" explores how materials behave and change in a vacuum.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Homemade Rain Gauge
Source Institutions
In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.
Translating an Alien Message
Source Institutions
In this activity, learners work together to interpret an "alien message." The group pretends that this is the only message from an imaginary civilization, so there is no "key" and thus no "correct" wa
A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.
Tsunami: Waves of Destruction
Source Institutions
In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Telescopes as Time Machines
Source Institutions
This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.
Evolution in Action: Isolation and Speciation in the Lower Congo River
Source Institutions
In this guided discussion activity, learners watch a video about Central Africa's Lower Congo River, one of the most biologically diverse rivers in the world.
Supernova Star Maps
Source Institutions
This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.
A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.
