This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

Can you avoid the body's immune system and make someone sick? Play this online game in which you go inside a human body to explore how viruses attack cells in the body.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

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 related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

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.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.
