Dinosaur and DNA Days
Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...
Curated OER
Types of Bonding Lab
Chemistry lab learners experiment to identify a series of unknown compounds. They choose which tests to perform, but you may suggest melting or boiling point, solubility, electrical conductivity, and malleability. This is a terrific...
