This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

Role-playing the parts of chromosomes and centrioles, learners use large chromosome models and nylon cords (spindle fibers and cell membranes) to walk through the processes of mitosis and meiosis.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

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/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

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

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

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.

This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.
