This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

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

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

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 perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners will explore how the human brain interprets environmental stimuli.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

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

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

In this activity, learners are divided into teams.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.
