In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

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

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this space science activity, learners explore transits and the conditions when a transit may be seen.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners discover how solar energy can be used to heat water.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
