In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

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 biology activity (page 6 of the PDF), learners roll a die to create a simple model that teaches them about the factors contributing to heart disease.

In this genetics meets math activity, learners take inventories of their own easily-observable genetic traits and compare those inventories with other learners in groups.

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

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

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

This "concept demonstration" provides learners with a concrete example (a pair of shoes in a classroom "cell") of what homology means.

In this activity, learners play a matching game with their families to discover common inherited traits and traditions. Learners distinguish between inherited traits and learned traditions.

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

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

To discover the risk and protective factors involved in substance addiction, learners play a game of chance to determine whether a fictitious child is likely or unlikely to abuse drugs.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.
