In this simulation activity, students experiment with a population of M&M candies or paper dot "beetles" to test how well each color is adapted to survive on a field of colorful wrapping paper or fabric. Students act as predators and see that... (View More)

This textbook chapter introduces the buffalo as a keystone species, and describes the environmental impacts of its near extinction, including today’s predominance of non-native species in the Great Plains. Human activities that contribute to... (View More)

Through an analysis of data sets on four parameters - sea ice totals, sea surface temperatures, near surface temperatures and surface type - students must decide whether the Arctic is experiencing climate change and predict any potential effects on... (View More)

In this activity, students identify habitats in Arizona, define and illustrate a food web in a kinesthetic exercise, and explain the importance of biodiversity in a writing assignment. Required materials include a ball of yarn or string. The... (View More)

In this laboratory activity, students investigate chromophoric dissolved organic matter (CDOM) through gradual dilution of black, green and chamomile tea. Through this activity, students discover how CDOM can dominate the absorption of sunlight, how... (View More)

This kinesthetic activity simulates the process of evolution by natural selection. Students take on the roles of crab-like predators that exhibit one of four variants of feeding appendage: a spoon, fork, knife, and chopsticks. The simulation runs... (View More)

Students learn about the connections between organisms in the ocean in this kinesthetic activity. Each student is given a card, identifying an organism, its food source, and its predators. Holding the end of a ball of yarn firmly, the ball is passed... (View More)

Highly productive commercial agriculture, known as industrial agriculture, is the focus of this investigation. Students will analyze and compare the inputs and outputs of industrial agriculture after reading background information, examining photos... (View More)
