Science of NHL Hockey: Force, Impulse & Collisions
https://www.oercommons.org/courses/scienceofnhlhockeyforceimpulsecollisions
NHL hockey pucks are made of vulcanized rubber and weigh between 5.5 and 6 ounces (160  170 g). During a game, every movement of the puck follows the laws of physics and illustrates the concepts of force, impulse and collisions. "Science of NHL Hockey" is a 10part video series produced in partnership with the National Science Foundation and the National Hockey League.

Energy of Motion
https://www.oercommons.org/courses/energyofmotion2
By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated by pendulums and roller coasters. They come to understand that energy can change from one form into another, and be described and determined by equations. Through the example of a waterwheel, the concepts of and differences between work and power are explained and calculated. Conservation of momentum and collisions are explored, with analogies to popular sports (billiards, baseball, golf), and how elastic and inelastic collisions are considered in the games' design. To show another energy transformation concept, the behavior of energy dissipating into heat by means of friction is presented. Students learn to recognize static friction, kinetic friction and drag, how they work, and how to calculate frictional force. A final lesson integrates the energy of motion concepts, showing how they are interconnected in everyday applications such as skateboards, scooters, roller coasters, trains, cars, planes, trucks and elevators. Through numerous handson activities, students swing pendulums, use plastic twoliter bottles to construct model waterwheels, bounce different types of balls, use weights to generate friction data, and roll balls down ramps to collide into cups.

Bouncing Balls
https://www.oercommons.org/courses/bouncingballs2
Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.

Collisions and Momentum: Bouncing Balls
https://www.oercommons.org/courses/collisionsandmomentumbouncingballs2
As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions. Many sports and games, such as baseball and pingpong, illustrate the ideas of momentum and collisions. Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.

Puttin' It All Together
https://www.oercommons.org/courses/puttinitalltogether2
On the topic of energy related to motion, this summary lesson ties together the concepts introduced in the previous four lessons and show how the concepts are interconnected in everyday applications. A handson activity demonstrates this idea and reinforces students' math skills in calculating energy, momentum and frictional forces.

Crash! Bang!
https://www.oercommons.org/courses/crashbang2
Students learn about the physical force of linear momentum â movement in a straight line â by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the "big mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.

E.G. Benedict's Ambulance Patient Safety Challenge
https://www.oercommons.org/courses/egbenedictsambulancepatientsafetychallenge2
Students further their understanding of the engineering design process (EDP) while applying researched information on transportation technology, materials science and bioengineering. Students are given a fictional client statement (engineering challenge) and directed to follow the steps of the EDP to design prototype patient safety systems for smallsize model ambulances. While following the steps of the EDP, students identify suitable materials and demonstrate two methods of representing solutions to the design challenge (scale drawings and smallscale prototypes). A successful patient safety system meets all of the project's functions and constraints, including the model patient (a raw egg) "surviving" a frontend collision test with a 1:8 ramp pitch.

Asteroid Impact
https://www.oercommons.org/courses/asteroidimpact2
Through this earth science curricular unit, student teams are presented with the scenario that an asteroid will impact the Earth. In response, their challenge is to design the location and size of underground caverns to shelter the people from an uninhabitable Earth for one year. Driven by this adventure scenario, student teams 1) explore general and geological maps of their fictional state called Alabraska, 2) determine the area of their classroom to help determine the necessary cavern size, 3) learn about map scales, 4) test rocks, 5) identify important and notsoimportant rock properties for underground caverns, and 6) choose a final location and size.

Testing the Caverns
https://www.oercommons.org/courses/testingthecaverns3
Students build model caverns and bury them in a tray of sand. They test the models by dropping balls onto them to simulate an asteroid hitting the Earth. By molding papiermÃ¢chÃ© or clay around balloons (to form domes), or around small cardboard boxes (to form rectangular structures), students create unique models of their cavern designs.
