Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

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

This activity is about collecting and analyzing DNA as part of a criminal investigation.

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 game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

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

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

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.
