Curated OER
DNA Extraction
Students extract and observe a visible amount of DNA from Escherichia. coli cells. They discuss the properties of DNA. Confirmation of the presence of DNA by a reaction with an indicator is confirmed within this lesson. Many hands-on...

DNA from the Beginning Study Guide
Students complete a study guide using a website which is an animated primer on DNA, genes, and heredity. The Web site is organized around key concepts. The web links and study guide are included.

Constructing a Phylogenetic Tree Using DNA Sequence Data
Students analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them. They take the role of molecular biologists and make genetic changes and constructing...
Curated OER
Controlling the Code: Molecules at Word
Students investigate how cells determine which genes will be expressed and which will be silent. In this genetics instructional activity, students use on-line resources to complete a worksheet and gather information about gene...
Curated OER
Using Amino Acid Sequences to Show Evolutionary Relationships
Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...
Curated OER
Physiological Adaptations
Students investigate the concepts of genetics and how it is tied to the variations found within different species and how it is tied to adaptations. They review the theory of evolution and factors found to help create variation. The...
Curated OER
Genetically-Modified Food
Students investigate the pros and cons of genetic engineering. They watch a short Bill Moyers video, conduct Internet research, create a poster, participate in a pro/con debate, and write an essay expressing their personal feelings on...
