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...

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Students describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.

Students pretend they are each genetic engineers with a test tube of unknown DNA (PCR'd) possibly taken from blood cells of someone with a genetic condition.

Seventh graders describe the processes involved in mitosis and meiosis. In this life science instructional activity, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to...

Most pupils know about the flu, HIV, and other viruses, but they don't know what each actually looks like. This interactive shows their relative size, structure, and allows for comparisons. It stresses the similarities and differences...
