"Who Done It?" Analysis of Molecular Fingerprints Left At the Scene of the Crime
Students examine different types of DNA fragments. They record and analyze their results. They determine who is the criminal in the story.

Infectious Disease Case Study Part I
Eleventh graders work together to complete a simulation on infectious diseases. They determine which concepts affect a disease more. They complete discussion questions as well.
Curated OER
Macro-DNA: Doing DNA Fingerprinting
Students explore gel electrophoresis using paper models. They model DNA sequences and shade the boxes on their Gel Electrophoresis Sheet which represent the individual fragments.
Curated OER
Sea Urchin Embryology
Students explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...

Macro-DNA: Doing DNA Fingerprinting and Gel Electrophoresis
Students create numbered DNA sequences by taping together the order of the sequence. They count the number of bases in their RFLP's and shade the boxes on their Gel Electrophoresis sheets that represent individual fragments. They...
Curated OER
Genetic Engineering/Biotechnology
Students create a paper model of a plasmid and insert a DNA molecule that contains a specific gene into the plasmid. They complete an actual transformation involving E. coli bacterium and relate the two activities to one another.
Curated OER
Diversity of Life
Students study fungi and its characteristics. In this fungi lesson students collect and observe fungi then answer questions on what they saw.
Curated OER
DNA Fingerprinting: You Be the Judge!
Learners explore DNA fingerprinting. Students discover how DNA fingerprinting is done and judge the validity. They evaluate the use of certain prints in courts and address the ethics of establishing a national database of fingerprpints.
Curated OER
Molecular Evolution in Plants
Students examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
Curated OER
Lost Baby
Students simulate the steps involved in creating a DNA fingerprint by the RFLP technique. They analyze RFLP patterns to determine the parentage of a missing baby.
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
Wolf Pack in a Bottle
Learners participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Cell Transformation in Tobacco Leaf Disks
Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...
