EVOLUTION: UNITY & DIVERSITY
Natural Selection— Super Value Kit
In this simulation of the classic peppered moth natural selection study, students assume the role of predatory birds capturing moths on a bark background. Results show firsthand how the moths’ population directly relates to environmental conditions and
how natural color variations affect survival odds. Analyzing data after the experiment, students see how a change in the popula- tions of certain phenotypes of moths was caused by human pollution.

Fun with Classification—Super Value Kit
Keeping track of more than 2.5 million living organisms is daunting, so biologists rely on clas- sification. In this hands-on activity, students work in groups to identify unique, distinguishing features of rubber fishing lures and develop dichotomous keys for classification. Students then exchange their keys and lures with other groups to see if they can classify the lures.

Adaptations—Activity-Stations Kit
Studying Seed Evolution Using Histograms— Student Laboratory Kit
Looking for a creative way to teach evolu- tion? Study seed evolution by making histograms! Evolution often conjures mental images of monkeys to cavemen to modern humans. In reality, evolution can be studied on a much simpler scale. Measure mass and length of sunflower seeds to see how such traits are selected in nature. Histograms created from the data allow students to analyze the frequency and symmetry of distribution and draw conclusions about the natural selection of seed size.Complete for 30 students working in pairs. Five calipers
Includes four activity stations exploring the concept of adaptations! Learn the advantages of having an opposable thumb by conducting various tasks without one, put depth perception to the test by using only one eye, see how concealing coloration gives one organism an advan- tage over others, and investigate how well feathers provide insulation.
FB2197 I $59.95 are included for student groups to share. Additional calipers are available separately.
