Times have changed—and so have science practices. An introductory lesson describing the components of DNA begins with a discussion of the discovery of DNA and its perception in different cultures and genders. Scholars then learn about...

Let's get a closer look at DNA and other molecular structures. The first instructional activity in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The...

Students complete a variety of activities as they study the historical story of Rosalind Franklin not receiving credit for her contributions in discovering the structure of DNA.

Show your class why restrictions aren't always a bad thing. In the third segment of a four-part series, the instructor develops the idea of restriction enzymes. Pupils learn how scientists use restriction enzymes in DNA analysis and DNA...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Students brainstorm a list of science discoveries and inventions that they think are important. They work in small groups, students examine 1-3 science discoeries more closely. Each group needs a recorder, and they answer three...

Pupils identify the structures that actually assort independently. They are taught how gene maps are produced. Students compare the processes of mitosis and meiosis. They are shown their (mitosis and meiosis) significane to sexual and...
