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

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

In this creativity-based activity, learners imagine what the Earth will look like in the near and distant future, then design their own future habitat and creatures that may live there.

This lesson plan revolves around studying the speciation of the Galápagos mockingbirds, which are on display at the California Academy of Sciences.

In this activity (p.7-8 of PDF), learners examine fossil formation.

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

This activity (on page 3 of the PDF under GPS: Biodiversity Activity) is a full inquiry investigation into biodiversity.

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

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

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 interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

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 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 count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

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

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
