Comparison of Normal vs Mutant Zebra Fish Embryos
Students 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.

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...

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
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.
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...
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 lesson plan 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...

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
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.

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.
