Pass It On Drawing red and white beans from a jar is an easy way for students to see how chromosome pairs determine whether a person is male or female. The activity also helps them understand that the assortment of chromosomes that pass from parents to offspring is random. For best results, have students work in groups of five.
Productive Plants In this activity, students design a scientific investigation to test a variable in the growth and reproductive rate of plants. Then they consider how using genetically modified plants (designed to grow rapidly from seed to seedling to plant) would affect their experiment. For maximum impact, select at least one experiment for the class to test.
