In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

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

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, 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 activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

Learners draw and describe a leaf, and then re-find leaves drawn and described by other learners. Learners can observe leaves outside, or leaves may be brought into the classroom.

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

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.
