Students review the unit on evolution and natural selection by playing a card game. Students take turns drawing a card from the stack and reading the question out aloud. The reader gives an answer. The other students, in turn may pass or challenge an answer. The correct answer earns the student a point.
The best way to understand a persuasive argument is to engage in one. Thoughtful thinkers identify several species that have been relocated by human intervention and the reasons for that intervention. They outline arguments for and against the wisdom of such human manipulation of other species.
Ancient coral beds give scientists clues to past ocean temperatures in much the same way that tree rings indicate historical weather conditions. High school scientists examine coral oxygen isotope ratios and plot the data as a function of the age of the coral. They relate their findings to climate change. Many resource links are included that can lead to extension activities.
Students perform an experiment to demonstrate the principles of antibody-antigen binding, the secondary immune response, cross reactivity, and complement fixation. The materials to be used include antibodies from a rabbit that was injected once with red cells from a sheep and also one that was injected three times with the red cells from a sheep.
Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes to condcut water quality testing for: dissolved oxygen, nitrates, pH, temperature, phosphorous and produce computer printouts of the data collected.
Learners discover the uniqueness of deep sea hydrothermal vent organisms through an exploration of the NOAA Galapagos Rift Expedition. They study the genetics and evolution of a shrimp species that lives near the vents then they design another species of shrimp that could survive in a different portion of the rift.
In this primate evolution worksheet, students will review the structures and functions that are characteristic of primates. Students will identify the differences between Old World monkeys, New World monkeys, and prosimians. This worksheet has 5 true or false, 20 matching, 3 fill in the blank, and 5 short answer questions.
Compare various types of biological diversity in a coral reef and calculate a numeric indicator that describes the diversity found in coral communities. Your class can work in groups to look at the abundance and distribution data of species in two communities. This instructional activity gives the opportunity to study both the biological topics and statistical mechnisms.
