This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

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