ON THE SPOT!

• Rules:– One member from each team will come up and take a

sound maker. The first to make a sound will have the first chance to answer for a point.

– I will need a score keeper that will keep score.

– If you are unsafe with the tools you will forefit your spot.

– Have fun and use this game to help you study for your test!

Energy can be transformed within a system or transferred to other systems or the environment.

Give an example of energy transfer.

Energy can be transformed within a system or transferred to other systems or the environment.

Give an example of energy transfer.Burning coal to generate heat which rises and turns a turbine which turns mechanical energy to electrical energy.

Trace the changes of energy forms, including thermal, electrical, chemical, mechanical or others as energy is used in devices:

A light bulb

Trace the changes of energy forms, including thermal, electrical, chemical, mechanical or others as energy is used in devices:

A light bulb:

There are many ways the light bulb could have received its energy. Here is one:

The lightbulb gives off thermal and light energy. It received electrical energy from a power plant that converted atomic energy (and heat energy) to electrical energy through a generator.

Give me an example of a natural resource

Give me an example of a natural resource

• Natural resources occur naturally within environments that exist relatively undisturbed by humanity, in a natural form.

• Examples of natural resources are air, water, wood, oil, wind energy, hydro-electric energy, iron, and coal.
