The Electrophoresis of Human Hemoglobin
Learners 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...
Curated OER
E.coli and their Human Environment
High schoolers observe how environmental changes (antibiotics) can affect the growth of E.coli, the rod shaped intestinal bacterium. They use the "F" test for statistical analysis. Students
Curated OER
Lotic Environment Lesson Plans
Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.
Curated OER
Aphids and Ladybirds
Students record observations of ladybird beetles and aphids. They develop questions concerning the behavior of ladybird beetles and aphids that are testable by a classroom experimentation. Students develop an investigation.
Curated OER
Forest Management
Students explore the changes in the Sequoia forest ecosystem. They evaluate reasons for the changes and discuss opposing views of human activity, logging and fire management practices. Students observe a video, describe the location of...
