How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...

Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Does a protein or DNA store genetic instructions for life? Follow the research from the 1920's experiments on mice through the 1940's experiments on bacteria to learn the answer to the difficult question. Scholars use an online...

Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

The experiment known as one of the most beautiful experiments in biology changed the way we think about DNA. Learn about the experiment and the scientists who designed it—as well as the scientists who built on the results—with an online...

When DNA research first began, it required almost an entire day to extract the molecules from a cell nucleus. Now it requires less than an hour. Scholars learn about the early theories of DNA with an online interactive, videos,...

In this biology instructional activity, students complete 28 short answer questions on fungi. They color and label the different parts of a hyphae.

Learn how the enzymes in the digestive system help with the digestive process in the human body.

Explore information about enzymes in the science of biology including what they do, how they work, and things that affect enzyme activity.

This lesson focuses on enzyme-catalysed reactions and the effect of temperature, substrate concentration, and pH on the reaction rate. It provides a link to an assessment.

This virtual laboratory demonstrates how an enzyme-linked immunosorbent assay (ELISA) is carried out and some of the key experimental problems that may be encountered. Students will learn about the assay procedure and the equipment and...
