What is the Evidence for Evolution?
Students identify one object that would tell the story of their lives. In groups, they determine what can and cannot be told from objects left behind. After watching a video, they compare and contrast chicken bones to human bones. To...

Superbugs and Antibiotic Resistance
Students complete experiments on antibiotics and antimicrobials. In groups, they explain how antibiotics affect the evolution of microorganisms. They test various types of bacteria to discover how much resistance they have to antibiotics.
