Objective: YWBAT give examples of energy conversions among the different energy forms.

Drill: Describe how turbines can be used to produce electricity from running water.

HomeworkHomeworkStudy WOW

The falling water (kinetic) turns the turbine, which turns a crank

on a generator (mechanical), causing it to produce electricity.

Did you know…?A computer-controlled electronic circuit allows turbines to generate current with a constant frequency, regardless of wind speed.

Energy Conversion Diagrams

Draw cross sections of the following topics, Hair dryer, wind turbine, car engine, riding a bike, water wheel, electric generator, light bulb, toasterThe cross section should include.

Be sure to include:

--A detailed diagram of how the structure works.

--A list of the specific energy conversions and where they occur

Closure

What part of the hair dryer changes electrical energy into mechanical energy into kinetic

energy?

Conclusion Answer

The motor changes electrical

energy into mechanical energy

which converts into kinetic

energy as the fan blades move.
