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).

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

Millions of organisms can live in and around a body of water.

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

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en línea, en libros de consulta, y en calendarios y almanaques.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

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.

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.

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

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 activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

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.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.
