In this outdoor activity/field trip, learners explore an aquatic site such as a pond, lake, stream, river or seashore to find and investigate plants and animals that live in water.

In this activity, learners discover how landfills affect the natural environment.

In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.

In this construction activity, students use a 2-liter bottle to build a fly trap.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of

In this hands-on activity, learners discover the similarities and differences between a vertebrate and invertebrate by dissecting a perch and a crawfish.

This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

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

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this activity, learners build a bird feeder or feeders to attract birds for observation.
