Not Just a Bag of Beans

This editable instructional activity 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....

Now you see it, now you don't! The stick bug exhibits the ability to disappear into a wooded environment. Why does this adaptation manifest in some species, but not in others? Life science students explore animal adaptations in nature...

Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

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 is...

The lecturer describes how specific characteristics develop. In this case, he discusses eye marking. The impact of environmental factors significantly influences the likelihood of successful reproduction, as favorable genes are more...

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...

What is a theory? Learners are primed for a lesson on theory, science, and the use of scientific evidence as it's used to prove evolution. This is a great video for elementary schoolers and can be used to introduce the concept of...
