This lab activity has learners create a pendulum with a one-second period.

In this activity, learners explore how nanosized structures can create brilliant color.

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

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

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

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

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

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

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.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

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.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).
