The Electrophoresis of Human Hemoglobin
Learners are presented with a scenario that requires them to electrophoreses human hemoglobin samples in order to confirm a diagnosis of sickle cell anemia and/or to determine whether individuals in the scenario are carriers of the...
Curated OER
Identification of Animals by Serum Electrophoresis
Students compare their unknown serum against a set of known serum standards and determine the animal source of their serum. They write a lab report to communicate their results.
Curated OER
The Electric Sieve
Students examine different mixtures and how they can be separated. In this electric sieve instructional activity students complete an activity that allows them to separate mixtures.

Project Wetlands
Students develop a joint undertaking designed to solve an environmental problem in their local community. They tackle the problem of erosion of banks and chemical run-off into a nearby lake, which is within walking distance of school.
Curated OER
DNA Fingerprinting through a Chemistry Lens
Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".
Curated OER
The Electrophoresis of Human Hemoglobin
Students analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of...
