Thursday, September 03, 2015 A-Day Objective: YWBAT explain the role of machines in energy conversions. Drill: What is an energy conversion? Give an example of a machine that is an energy converter, and explain how the machine converts one form of energy to another. Homework Study WOW

A wind turbine converts the kinetic energy of the wind into electrical energy.

Did you know…? The pedicar, introduced in 1973, was a pedal- powered, one- passenger, all weather vehicle. It was conceived as an alternative to the gas-powered automobile and cost about $550. It could reach 15 mph.

Today’s Activities  Drill  Review Test  Energy Conversions  Conclusion

Energy Conversions Diagrams Draw a cross section of the converters below. The cross section should include.  A detailed diagram of how the structure works.  A list of the specific energy conversions and where they occur Converters: Hair dryer, wind turbine, car engine, riding a bike, water wheel, electric generator, light bulb

Closure What is the role of machines in energy conversions?

Conclusion Answer Machines transfer energy from one object to another to make work easier. For example, when you use a crowbar to remove a hubcap, you transfer energy to the crowbar and the crowbar transfers energy to the hubcap. The way the energy is transferred determines how much easier the work is to do.
