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

In this activity, learners use models of fossilized dinosaur teeth to understand how dinosaur teeth were used.

In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners play bingo to learn about the diversity of birds. This game includes a warm-up lesson and "Full Flight" version.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.

In this online simulation, learners can see adaptation and camouflage in action.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

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

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this online activity, learners create monsters and see how they survived when released into the wild.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.
