In this introductory activity, students will read two articles about the issue of fish mislabelling and complete two graphic organizers to identify the issue, its implications and possible solutions. They will complete the organizers individually and in pairs, and then discuss the results with the whole class.

Learn how chemistry and genetics makes redheads stand out from the crowd.

Scientists have accumulated so much evidence in the theory of evolution that it is one of the most widely-accepted theories in science.

Ever wonder how fish survive in the cold waters of the Arctic and Antarctic? It’s partly because of a brilliant evolutionary adaptation.
