This is a QR code. A QR Code is a 2-dimensional barcode, which has encoded in it a URL (web address), text, or other information. It can be read by a QR code scanner, including QR scanner smartphone apps. Once you have an app installed on your smartphone, open the app and hold your phones camera over a QR code to read it. Most QR codes youll come across have a URL encoded, so chances are when you read the QR code it will take you to a web page.

This tutorial/simulation consists of three topics. In topic 1, students follow Darwin on a virtual field trip around the world in order to debunk three common misconceptions about natural selection. Students will: 1) complete interactive explorations of each misconception and explain that: a) fitness involves survival and reproduction, not just survival, b) selection is not random, and c) populations, not individuals, evolve; and 2) construct a definition of natural selection. In topic 2, Students play an interactive game, “Fitness Fever” to learn the underlying genetic variation that natural selection acts upon. Students will: 1) learn about three single-locus traits known to be acted on by natural selection in animals, plants and bacteria; 2) rate the fitness of genotypes given an environmental context; and 3) select changes that enhance fitness of an organism. In topic 3, 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 selection acts on populations.
An excellent interactive exercise that investigates the concept ofnatural selection. Students are required to draw conclusions from information and data provided. This is currently used in my classes. Very well organized and well written.

It is a fun way to learn about the process of evolution

This is great for our evolution unit and it ties in perfectly with information we have already talked about during genetics and cell division!!
