Curated OER
Acid Rain Simulation
Students collect data on causes of Acid Rain. In this science lesson, students simulate the effects that produce acid rain, collect and analyze data from their samples. They relate science and statistics in this lesson.
Curated OER
Rainbow Electrophoresis
Students are introduced to the principles of gel electrophoresis and also provides an opportunity for students to practice loading gels and prpetting. In this laboratory activity, food color is used to separate into constituent pigments.
Curated OER
What is DNA? DNA Extraction from Kiwifruit
Students isolate DNA from kiwi cells, spool DNA from a kiwi, describe role of the DNA and genes, and explain how knowledge of DNA and genes can be used in genetically modifying foods.
Curated OER
Chlorophyll
Middle schoolers use thin layer chromatography, TLC, to separate various pigments found in plants.
Curated OER
DNA Extraction From Living Things
Students extract DNA from split peas. In this biology lesson, students hypothesize what DNA looks like and perform the experiment to verify their hypothesis. They explain the importance of DNA in living things.
Curated OER
What Does That DNA Molecule Really Look Like???
Students extract DNA from animal liver cells. They separate, collect and describe the appearance from the extracted DNA while role playing as an intern in a city's forensics.
