In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

Learners use a simple process to extract DNA from strawberries.

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

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

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 about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

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

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

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 game, learners cross off or color bingo squares in response to questions about their traits.

This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.

In this activity, learners investigate variations in human traits. This allows learners' natural curiosity about their identity to draw them into the study of heredity.

In this two-part activity, learners compare and contrast a variety of life cycles to better understand different organisms and how they develop.

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