In this activity, learners model erosion using a clear shoebox and sand or soil.

In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

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

In this activity, learners create a biosphere in a baggie.

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

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

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

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, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Learners develop an understanding of air pressure in two different activities.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this family or group activity, learners create a nature journal by visiting a local nature center or backyard, observing creatures in their natural habitats, and sketching what they see.

April showers bring May flowers, but what do coastal storms bring?

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery
