In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

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

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.

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

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

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 model directed evolution by making paper fly. Learners construct and fly paper airplanes.

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

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 activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

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.
