• ### What do Bone and Silly Putty® have in Common?: A Lesson on Bone Viscoelasticity

Learning Objectives
• Students will be able to explain how the anatomical structure of long bones relates to their function.
• Students will be able to define viscoelasticity, hysteresis, anisotropy, stiffness, strength, ductility, and toughness.
• Students will be able to identify the elastic and plastic regions of a stress-strain curve. They will be able to correlate each phase of the stress-strain curve with physical changes to bone.
• Students will be able to predict how a bone would respond to changes in the magnitude of an applied force, and to variations in the speed or angle at which a force is applied.
• Students will be able to determine the reason(s) why bone injuries occur more frequently during athletic events than during normal everyday use.
• ### Furry with a chance of evolution: Exploring genetic drift with tuco-tucos

Learning Objectives
• Students will be able to explain how genetic drift leads to allelic changes over generations.
• Students will be able to demonstrate that sampling error can affect every generation, which can result in random changes in allelic frequency.
• Students will be able to explore and evaluate the effect of population size on the strength of genetic drift.
• Students will be able to analyze quantitative data associated with genetic drift.
• ### It's a bird! It's a plane! It's biomechanics!

Learning Objectives
Students will be able to:
• identify and define forces that act on an object in flight.
• understand the definition of Newton’s third law of motion, which states that with every action there is an equal and opposite reaction, and apply this principle to explain pressure differences and lift generation.
• generate hypotheses about animal flight efficiency based on examining morphology (anatomy).
• generate hypotheses correlating wing size and performance during flight.
• apply their understanding of wing designs and wing relationships to total mass.
• compare flight principles among animals to understand the co-evolution in several animal groups.
