Comparison of Normal vs Mutant Zebra Fish Embryos
Young scholars observe and study mutations. In this mutations lesson, students work in groups to complete observation tables of various mutations of the zebra fish embryos. Groups give presentations about their observations.

Characterizing Drosophila Mutants
Learners investigate wild-type and several mutant varieties of Drosophila melanogaster, which are characterized and distinguished according to pteridine pigments. They discoverthat paper chromatography of the wild-type Drosophila results...
Curated OER
Inheritance in Maize
Students use mutant corn ears to investigate inheritance patterns. In this inheritance lesson plan, students count the number of corn kernels of each phenotype in mutant and wild type ears of corn. Students calculate the ratio of...

Yeast: A Dihybrid Cross
Students create a yeast dihybrid cross and follow two forms of each of two traits: red growth versus cream color, and tryptophan-dependent versus tryptophan-independent. They complete diagrams to represent the alleles, predict the...
Curated OER
Drosophila Melanogaster
Student manipulate flies, examine their external anatomy, begin a fly journal and make cultures of wild type flies. Students cross wild type flies and mutants, both purchased from a biological supply house (Carolina Biological Supply...
Curated OER
Drosophila Melanogaster
Students cross wild type flies and mutants, both purchased from a biological supply house (Carolina Biological Supply or Wards, for example) in groups from instructional activity one.

How Mutations Lead to Changes in Cell Structure and Function
Pupils investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare and...
Curated OER
Photosynthesis
Students conduct a variety of experiments on photosynthesis. In this biology lesson, students identify the factors required for the process to occur. They perform computerized experiments to test the amount of oxygen produced when plants...
Curated OER
Mutations--Preexisting or Acquired?
Students state the controls and variables of the Newcombe spread experiment. They state a hypothesis for the Newcombe spread experiment. Students distinguish between the characteristics of a preexisting mutations and those of an...
Curated OER
Mutations--Preexisting or Acquired?
Students explore the reasoning and experimental approaches to mutations. They expose a culture of E. coli to virulent bacteriophage and observe whether mutations of the cells existed previously or if the bacteria mutated as a response...
Curated OER
Molecular Evidence for Evolutionary Relationships
Learners compare the amino acid sequences in cytochrome-c for a variety of organisms and use this information to infer evolutionary relationships. Students investigate the role of homeobox genes and what this indicates about the...
Curated OER
Yeast - A Dihybrid Cross
Students make a yeast dihybrid cross and follow two forms of each of two traits: red growth versus cream color, and tryptophan-dependent versus tryptophan-independent.
Curated OER
Evaluating Information Resources
Students identify at least five aspects to be examined in determining the validity of information presented on a website. They classify websites into highly trustable, trustable or questionable information sources. In addition, they...
Curated OER
How Can We Observe Genetic Variation Within a Species?
Students observe intra-species variation by completing standard microbial streaking procedures. They collect data from which they draw observations and complete a worksheet.
Curated OER
Natural Selection Simulation
Students simulate the changes in a natural population of birds or other species. They establish baseline data of population fluctuation for a closed population with a stable food supply. They graph the data to complete their mutations.
Curated OER
Drosophila Melanogaster
Students manipulate flies, examine their external anatomy, begin a fly journal and make cultures of wild type flies.
Curated OER
Drosophila Melanogaster
Students collect their own flies and construct crosses, then compare them to the data from lesson two.
Curated OER
Superbugs: An Evolving Concern
Students investigate the growth of bacteria in the presence of antibiotics. They write a hypothesis, conduct an experiment to test their hypothesis, analyze the results of their bacterial growth experiment, and describe the results on a...
Curated OER
Lights On - We Have A Quorum
Students explore basic bacteriological techniques. They investigate cell to cell communication and become aware of the environmental and evolutionary implications of this communication.
Curated OER
Bacterial Transformation
Students explore DNA recombination. In this biology lesson, students observe the growth of microscopic species. They predict the phenotype of the transformed colonies.
