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 to protect their skin while applying pesticides to plants.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

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.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

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.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

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

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

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

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.
