A Phylogenetic Perspective for the Cladistically Challenged

Students discuss biological diversity in ocean communities. In this diversity lesson, students examine the variety of organisms compared to relative abundance. They will write an analysis and discuss their findings with the class.

Three lessons and five assessments are contained in this material. Various paper shapes are sorted as a simulation of biological classification. Learners gather a list of living things that they are familiar with and design a...

Students write an essay about the coral reefs. In this oceanography lesson, students investigate the reef of Bonaire and compare it to reefs that are not thriving. Students then explore the differences that contribute to the overall...

After reviewing biodiversity, learners work in small groups to analyze actual species distribution data. They learn to calculate the Shannon-Weaver diversity index for different communities. Though not particularly engaging, the content...

Pupils explore evolution in a scientific manner as they research the theory and conduct an experiment demonstrating evolutionary changes in modern-day beans and lentils to determine differences from those in the past. They complete an...

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...

Students view pictures of distant "cousins" to humans. They place them in order by their distance from humans. Students receive a packet of six pages featuring graphics and a cousins summary page. They work in groups to complete 5 cousin...

Students experience, through a "dig," the historical discovery of fossils which increasingly link whales to earlier land-dwelling mammals. They encounter the intermediate forms which show changes that lead to the modern whale.

Students read the essay, "What, If Anything, Is a Zebra?" following a teacher made reading guide. They investigate cladistics, shared derived characteristics, with further online research to enhance their study of evolution and...

Students use M&Ms to simulate radioactive decay of elements.
