The Making of the Fittest: The Birth and Death of Genes
Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Mitosis Cookies Activity
Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs, which...

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...

Variations in Living Things
Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

Icefish Blood Adaptations: Antifreeze Proteins
Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

Unit 3: Genetic Variation
What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

Building a DNA Molecule, Mitosis in Motion and Mutation Gossip
Students explore three lab experiments involving DNA, mitosis, and mutation. They complete activities and play games to review DNA, mitosis and mutation concepts. They build a DNA molecule and create flip cards representing mitosis in...

Genetic Variability
Using black and white construction paper, evolutionary biologists simulate the classic peppered moth study. They use beans in a frequency and natural selection exercise. Finally, they analyze germinated seeds for variations. All three...

Viruses/Infectious Diseases: What's Really Bugging You?
Middle school life science or health classes listen to an audio, visit websites, read different articles, and participate in a class-wide simulation about the spread of viruses. The lesson doesn't get into the mechanics of how viruses...

Transcription and Translation Lab Activity
Students investigate DNA strands. They study the sequence to determine if it is DNA or RNA and write the mRNA nucleotide sequence. After stringing the beads together to create the mRNA sequence they translate it into an amino acid...

Genes
Students explore the history, inheritance and mutations of genetics. In this genetic lesson plan students complete experiments on DNA sequences.
Curated OER
Spork and Beans
Students examine natural selection, how it works and how it can cause microevolution. In this evolution lesson plan students complete a lab activity that shows the effects that natural selection has on organisms.

Populations- The Survival of the Fittest
Students examine the ways that populations become diverse and how mutation changes the diversity of a population. In this exploratory lesson students study natural selection by completing a lab activity and discussing what they learned.
