In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this activity, learners explore how nanosized structures can create brilliant color.

The goal of this activity is to design, build and test a house or toy for an animal.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

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

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?

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 explore how engineers design devices that can detect the presence of pollutants in the air.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.
