In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.

In this activity, "write" a secret message in genetic code as beads on a string.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this biology activity (page 6 of the PDF), learners roll a die to create a simple model that teaches them about the factors contributing to heart disease.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

In this activity (on pages 22-33), learners do the kind of work genetic scientists do, sorting and comparing (images of) genetic material strands called chromosomes.

This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.

This activity (on pages 7-13) has pairs of learners survey an array of similarities and differences between them.
