As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

High schoolers work in groups to investigate and present genetic variation, adaptation, and sexual selection as it relates to evolution. In this evolution lesson, students watch a video discuss how the human eye could evolve due to...

Students research how sexual selection plays a role in driving evolution. They experiment how variation exists within not just obvious physical traits, but metabolically and behaviorally. They write a letter describing a problem, and a...

Young scholars pretend they are a scientist like John Endler in this Web activity. They visit his pools, from hypotheses, and test them out. In the process, the explore about natural selection and sexual selection. They are able to...

Biology learners tackle evolution-related concepts when viewing this collection of slides. There are no graphics or photos, just notes in bullet-point style detailing adaptations, evidence for evolution, mechanisms for change, and types...

Students discuss human behavior, sexual selection and the underlying genetic and evolutionary reasons for mate selection. The, in groups, they rate the attractiveness of certain individuals and measure facial features for symmetry.

Students are introduced to how the process of evolution works. As a class, they review the characteristics of natural selection and how those with advantageous traits reproduce and survive. To test this theory of natural selection,...

Learners examine the term natural selection and what behavioral adaptations are.  In this evolution lesson students view videos about evolution and perform experiments that simulate populations that interplay between the forces of...

High schoolers investigate genetics and evolution of species. They simulate the breeding of birds using origami birds. In addition, using dice they introduce genetic variation into the species.

Students research the theory of evolution and the controversy.  In this evolution lesson students view a film on Charles Darwin then they write an essay about whether or not intelligent design should be taught in science class. 

Young scholars examine the topic of evolution as it relates to biodiversity in various remote areas of the world. They watch videos, conduct Internet research, and in small groups create a digital video report to illustrate common...

Students explore natural selection. For this genetic adaptation lesson, students discover why certain traits continue and some traits disappear. Students discover how species evolve and change. Resources are provided.

Students examine natural selection, how it works and how it can cause microevolution.  In this evolution lesson students complete a lab activity that shows the effects that natural selection has on organisms.

Students recognize the concepts of evolution and natural selection as well as cladistics and phylogenetics. They observe the process of regeneration in a sea anemone to simulate asexual reproduction.

Students explain in their own words why organisms live together. In this biology activity, students model what happens to organisms if their environment changes. They explain the importance of evolution.

In this evolution worksheet, students review genetic variability, gene mutations, biodiversity and adaptations. This worksheet has 22 fill in the blank and 10 short answer questions.

Students explore evolutionary processes and theories using the spotted fish applet. They observe what happens to fish in a closed environment with both food and predators. Students run the model several times and answer questions about...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

Students examine the roles in which animals play in the pollination of plants. They recognize that flowers have male and female sexes. Students describe cross pollination and propose reasons for cross pollination through narration of a...

Describes some mechanisms in reference to the choosing of a mate. Both selection processes of males and of females are described. Discusses group sexual selection models and nonsexual selection models.

This two-part video series explores how females and males relate to each other in the animal kingdom. It shows how the strategies that males and females use to attract each other impact on the evolution of a species.

Wikipedia offers a site on the topic of sexual selection, including an image and a description of one of the most famous types of sexual selection.

This content from TalkOrigins.org is within a discussion of frequently asked questions about evolution. It discusses some basics about sexual selection. It also provides an explanation for the usual dominanceof the female in the sexual...

Scientific article explaining what natural selection is, and how it manifests itself through genetics and from generation to generation. Natural selection is compared to genetic drift, both of which cause evolution to occur. The limits...
