Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

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...

Frederick Sanger won two Nobel prizes for protein sequencing and DNA sequencing. Young scientists learn about Dr. Sanger's research and amazing discoveries. They read an article and a biography, view videos and animations, and apply...

Match up the DNA code. Pupils read the website from the American Museum of Natural History about how DNA can determine whether a skin is from a particular type of reptile. Using the same technique, learners match up products with the...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

Scholars become detectives and use science to solve a crime! A complete unit introduces DNA and includes hands-on activities that have learners model DNA and extract it from different food types. A culminating activity challenges...

For years, scientists believed tRNA was junk left over from larger RNA. Three scientists used different approaches to prove tRNA actually exists as the connection between DNA and protein. Learn about their experiments, their lives, and...

DNA writes 64 different words but only codes for 20 different amino acids. Budding scientists learn about where each of these numbers come from and why they aren't equal with an online interactive. The resource explains the research, the...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...
