LS4B - Natural Selection

This editable worksheet is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also...

A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

Charles Darwin and Jean Baptiste Lamarck are credited for developing the theory of natural selection. After teaching your beginning biologists about acquired characteristics, they read the included selection and answer questions that...

The peppered moth is featured in a video about natural selection. The narrator tells the story of Darwin's theory and then moves on to the principles behind natural selection and the different ways it works. Concepts covered include...

The evidence for natural selection is presented as a random variation of a characteristic allowing a particular strain of organism to survive with a higher probability of successful reproduction. Population change over a short period of...

Examine exactly what is meant by natural selection, as well as how it works in nature and through the assistance of humans. Presented with fun graphics and simple narration, the complex topic of natural selection is clearly explained in...

Selective breeding has resulted in some novel and beautiful or useful dogs over the years. Using the American Foxhound as an example, genetics learners find out how and why they came about. Then, in small groups, they select breeds to...

Viewers explore real-world examples of both evolution and natural selection as the instructor discusses changes to the environment, mutations causing changes in phenotypes and changing the fitness in organisms, and how humans are...

Between 1968 and 2002, the total number of peppered moths decreased by almost two thirds, although scientists do now know why. In the 10th video of the series, the instructor defines evolution as any changes to a gene pool. Scholars then...

Have your class do research on natural disasters and create a presentation using this resource. In completing this activity, learners apply the five geography themes to their research. They write a paper describing their results. It's a...
