In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

In this activity (on pages 24-34), learners explore the four-part stomach of cows (and other grazing animals called ruminants), and compare it to the human one-part stomach and its digestive process.

In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

This lesson introduces learners to the world of nematodes (roundworms).

In this activity (page 2 of pdf), learners craft a model of a skate egg case and come to understand that cartilaginous fish such as sharks and shakes employ reproductive strategies that differ from th

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).

Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.
