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

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

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.

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

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.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this activity, learners investigate the history and development of agricultural biotechnology.

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

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.

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

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

This activity models the mass coral spawning event that takes place at Flower Garden Banks National Marine Sanctuary every August.

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 examine antibodies and antibody recognition using a model.
