In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

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.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

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

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

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

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

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/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.

In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.

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 genetics activity, learners discover how to extract DNA from green split peas.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

Learners use a simple process to extract DNA from strawberries.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, learners start their own field journal to better understand the wildlife in their area.
