Enzymes
This multiple-choice and short-answer enzyme quiz would work well as a pre-post test in any biology class. To differentiate, use it as a group quiz with learners paired up to discuss each question.
Curated OER
Polymerase Chain Reaction Activity
Students explain the importance and function of enzymes. They compare and contrast the processes of DNA replication and polymerase chain reactions. They practice using new vocabulary as well.
Howard Hughes Medical Institute
Virus Hunters: Epidemiology of Nipah Virus
Who actually goes looking for a virus? Expose your class to the high-stakes life of an epidemiologist on the trail of the Nipah virus. Pupils engage in a short video, then examine how scientists predict, model, and find the source of...
