Curated OER
What Repair Proteins are Expressed in C-Ferns After Exposure to Varying Amounts of UV Radiation?
Students examine the life cycle of c-ferns. They complete experiments on the organisms exposing them to differnet amount of UV radiation. They collect data and analyze their results.
Curated OER
How Can We Extract Human DNA?
Students perform an experiment in which they extract DNA samples from hair samples. They follow a set procedure to extract the DNA and complete summary questions.
Curated OER
How is Foreign DNA Inserted into Organisms During the Genetic Engineering of Crops?
Students examine the positive benefits and negative consequences of genetically modified organisms following a lecture covering key biotech concepts and techniques. Students then conduct and experiment comparing the travel rate of...
Curated OER
Run-off Race
Students create wetland models in pans and use them to experiment to see how plants help slow the flow of runoff water and keep our waterways clean.
Curated OER
Build an Electrophoresis Chamber
Students explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.
Curated OER
Kidney and Related Concepts
In this kidneys learning exercise, students review the function of the kidneys including what happens when the kidneys stop working. Students also compare kidney function in fish, frogs, and kangaroo rats. This learning exercise has 86...
Curated OER
One, Two, Three. TMV
Learners, in groups, design their own experiments to determine how the mode of application of the virus extract affects the various plants that students have grown from seed.
Curated OER
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
Riparian: The Guardian of the Waterways
Learners become educated on what a riparian is, the need for riparian, and how a riparian corridor (forest, habitat) can protect waterways. Students construct dioramas depicting riparian habitats.
Curated OER
Meadow Study
Students examine insects they collect in a sweep nets. They identify as many of the insects as they can.
Curated OER
Forests
Learners examine soil in forests looking for animals and insects. They divide the animals based on their number of legs and draw the animal they have collected.
Curated OER
DNA Fingerprinting through a Chemistry Lens
Young scholars 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
Teaching Students How to Read the Protein Concentration in a Sample
Learners work together to identify proteins in different samples. They calculate the protein concentration in those samples as well. They complete discussion questions to end the lesson.
Curated OER
Molecular Evolution in Plants
Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
Curated OER
The Electrophoresis of Human Hemoglobin
High schoolers 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...
Curated OER
Molecular Evolution in Plants
Learners 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...
