Connecting Concepts: Natural Selection 3: Microevolution: Evolution in a Population
Students play the role of predators on moths on a tree trunk. Then, they play the role of biologist, analyzing the changing gene frequencies of the moth population and determining if the population evolved over three generations. Students will: 1) collect data by eating moths; 2) calculate gene frequencies for each phenotype over three generations; 3) interpret graphs of data their data to determine if microevolution occurred; and 4) explain how...

This website contains tremendous amount of ressources for students independant practice. It lays out a steps by steps aproach in teaching evolution. it has a lot of interactive activities that will help student mater microevolution and selection in a given ecosystem. I could use this website in my teaching of natural selection to compile activities for my students. Can also direct students to the website to practice a specific concept for homework. It also have a lot of links to other websites that shows the same concept.

A really useful interactive exercise to encourage students to think about selection pressures and work out allele frequencies over three generations.
Technical Remarks:
Last slide slightly confusing as it invites viewer to click on forward arrow for next. However, this is different to all preceeding slides, and the arrow it refers to is NOT on the slide but above it. A small hiccup in an otherwise great presentation.

Part three of three excellent interactive exercises on microevolution. The student is required to interpret data. If wrong answer submitted, they have to go back and redo the section. Well organized and accurate.
