- Abstract:
-
Students learn how engineers harness the energy of the wind to produce power by following the engineering design process as they prototype two types of wind turbines and test to see which works best. Students also learn how engineers decide where to place a wind turbine, and the advantages and disadvantages to using wind power compared to other non-renewable energy sources.

- Abstract:
-
After learning about transfer of energy, specifically the loss of kinetic energy to friction, students get a chance to test friction. In groups they are given a wooden block, different fabrics, and weights and asked to design the "best" puck. The class first needs to define what makes the "best" puck. Each group should realize that the most desirable puck will travel the furthest, thus the puck with the least amount of friction. In the context of hockey the "best" puck is the one that travels farthest and loses the least kinetic energy to friction. Students then need to apply their knowledge of friction to design a new optimal puck for the National Hockey League. The friction is the transfer from kinetic energy to heat energy.

- Abstract:
-
This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.

- Abstract:
-
That heat flows from hot to cold is an unfortunate truth of life. People have put a lot of effort into stopping this fact, however all they have been able to do is slow the process. Working in groups of three to four, students will investigate the properties of insulators in attempts to keep a cup of water from freezing, and once it is frozen, to keep it from melting.
