In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

In this activity, learners discover which plants and animals have symbiotic relationships and how this impacts each organism.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners discover why only some types of plastic can be recycled.

In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

In this creative outdoor activity, learners invent populations of make-believe organisms and then investigate real populations living in the activity site.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.
