At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Seventh graders describe the processes involved in mitosis and meiosis. For this life science lesson, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to review concepts...

Young scholars learn that heredity comes down to the flip of a coin with this cross-curricular math and science lesson. Using smiley faces as a model, students toss coins to determine which dominant or recessive traits...

Students study genetic traits using popsicle sticks as chromosomes. In this biology lesson, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

Students explain how cells reproduce. In this biology lesson, students transcribe and translate a gene. They discuss and compare their answers in class.

Tenth graders investigate the chemical composition of DNA and RNA and how they work together to synthesize protein. They discover genetic codes, gene chromosome theory, and how the environment influences our appearance.

Students examine the issues involved with using DNA evidence in a courtroom trial. They read and discuss a case study of a particular trial, conduct research, and role-play a jury by reporting their verdict and discussing how they...

Learners explore DNA microarrays. In this genetics instructional activity, students model DNA microarrays that are used by scientists. Learners work to determine levels of breast cancer genes in patients. They will determine the...

Tenth graders lake a karyotype from their chromosomes and diagnose the genetic problem (if there is one).

High schoolers investigate the progression of discoveries that have led to the genetics knowledge that scientists currently have. They determine how genetic experiments disproved previous theories on inheritance.

Seventh graders assume the role of stockholders in a fictitious biotech company. After investigating the cloning of pets, the effects of cloning on the health and well being of the cloned animal, and the ethical issues involved, groups...

Students explore human behavior by participating in a class science game. In this human characteristics activity, students identify different human traits that are passed down by each generation and the purpose each of them have....
