Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Natural Selection: Exploring the 'Ohi'a Common Garden
Seventh graders examine natural variation by visiting the Ohi'a Common Garden in Volcano, Hawaii. In this natural selection lesson, 7th graders study background information about phenotypes, genotypes, and phenotypic plasticity before...

Camouflage and Protective Coloration: A Model of Natural Selection
Students investigate natural selection and differential survival among divergent phenotypes of a population. Using everyday items , they model adaptations of camouflage and protective coloration in two very different environments.They...

Evolution and Adaptations
Survival of the fittest isn't just for the movies! A five-part lesson explores several different species with known adaptations and analyzes them for their survival strategies. Using both video and research data, scholars draw...

Color Variation over Time in Rock Pocket Mouse Populations
A species-specific look at natural selection, the resource herein examines how adaptations have helped the population of rock pocket mice survive in a changing landscape. To begin, middle or high schoolers watch a 10.5 minute video,...

Natural Selection
Young scholars practice calculating allele and genotype frequencies in the framework of a simple simulation using hard candy, calculators, and a worksheet. This lesson includes a three-page worksheet and an assessment question for...

Natural Selection in Protected And Unprotected Populations
Studnets compare how two elephant seal populations fare during successive generations. They participate in a simulation using a card game to look at the differences in two populations, one that is protected from mortality by human...

Selection and Variation in the Egyptian Origami Bird
High schoolers investigate genetics and evolution of species. They simulate the breeding of birds using origami birds. In addition, using dice they introduce genetic variation into the species.

Why do we need Vitamin C in our diet? Or Why do we carry old inactive genes in our genome?
Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Got Lactase? The Co-Evolution of Genes and Culture
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Characterization of the Bioluminescence (Lux+) Gene E. coli
Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

Mendelian Genetics
How did Mendel know which pea plants would demonstrate certain characteristics? Pupils explore the answer this question, among others, as they complete Punnet squares, research dominant and recessive traits, and explore hereditary...

"Chips" Off the Old Block?
Students study using analogies between common items or occurrences and science concepts. They use the analogy of cookie recipes to that of the DNA "recipes" for living things to help us explain more about mutations.

The Meaning of Genetic Variation
Students investigate variation in the beta globin gene by identifying base changes that do and do not alter function, and by using several Internet-based resources to consider the significance in different environments of the base...
