In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

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

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.
