This unit consists of five activities, all of which focus on the response of plant life-cycle events to climate change. Students participate in discussions, field observations, data collection and analyses, plant identification, seed dispersal... (View More)

This unit consists of two parts, each with several activities which require students to participate in investigations, discussions, computer data analysis, role-playing, and research. In Part 1, students examine the roles of Earth's energy balance... (View More)

Unit two of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in current climate. Students discover how carbon in Earth's system is monitored and also investigate the... (View More)

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)

This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (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)

In this activity, students develop a timeline relating technological advances, particularly in microscopy, to how scientists have classified living organisms throughout history. Students use Internet and/or library resources to investigate important... (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)
