In this bilingual (English/Spanish) activity, learners create family trees by tracing the hands of their family members.

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

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

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

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 explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners bake cookies by following different recipes to better understand genetic mutations. Everyone in the group bakes the same type of cookie: chocolate chip.

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.

Learners use a simple process to extract DNA from strawberries.

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

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