Learning the Structure and Function of DNA
Students read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.
Curated OER
Modeling Protein Structure
Students examine amino acids and discuss the properties of side chains. In this proteins lesson students demonstrate the foldings of peptides.

How Many Drops?
Students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny can hold.
Curated OER
The Structure And Functions of Proteins
Ninth graders investigate the structure of proteins and how it affects their function. They build a protein model with four helix units and describe how this structure aids the protein in doing its jobs.
Curated OER
Gel Electrophoresis Simulation
Students identify the steps in a gel electrophoresis experiment and describe the role of enzymes. They examine the relationship between fragment size and migration rate in a gel. They view DNA fragments as well.
Curated OER
How Is the Genetic Code Ultimately Translated Into a Protein?
Students examine the functions of mRNA, rRNA and tRNA. They explain the steps in the protein synthesis process. They practice using new vocabulary as well.
Curated OER
Identifying Food Nutrients
Young scholars pretend they are a food-quality tester. They develop a kit to test food for sugars, starches, proteins and lipids. They answer questions to complete the lesson.
Curated OER
Electrophoresis Analogy
Students participate in a simulation of electrophoresis separation of DNA fragments. They link arms to form DNA fragments with each student representing a nucleotide. As they move through an obstacle course they discover how fragments...
