Curated OER
Intro to Biology Chapters 1 & 2 Practice Test
Don't be fooled by the title - this biology quiz could serve as an AP biology or college-level biology quiz. Some of the molecules represented may be difficult to identify without seeing the textbook from which this is based. It could...

Producing a Strain of E. coli that Glows in the Dark
Learners observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

The Digestive System: Where Does Food Go?
Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...
Curated OER
Cellular Respiration Oxidation of Pyruvate Krebs Cycle
Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle. Students should be able to follow these slides...

How Genes Work Lesson Plan
Students define the key terms that are the structure and function of DNA. In this genetics lesson plan students complete a lab activity in which they construct a model DNA structure.
Curated OER
Insect Classification
Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.

Khan Academy: Test Prep: Mcat: Biomolecules: Enzyme Structure and Function
Enzymes create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a "catalyst." Enzymes are biological catalysts - they...
TED Talks
Ted: Ted Ed: Activation Energy Kickstarting Chemical Reactions
Chemical reactions are constantly happening in your body - even at this very moment. But what catalyzes these important reactions? Vance Kite explains how enzymes assist the process, while providing a light-hearted way to remember how...
