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
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
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
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
Curated OER
DNA Fingerprinting
Pupils experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
High schoolers 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
Separating a Starch-Glucose Mixture Using Gel Filtration
Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
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...
