 * //Nature of Energy (What is Energy?)//

Energy Types
The following types are considered: · Mechanical Energy · Heat Energy · Chemical Energy · Electrical Energy · Nuclear Energy · Wave Energy Students develop broad understandings about the features of each energy type. Test 1 Research Assignment 1

Renewable/Non-renewable Energy Sources
Students develop an understanding about the features of renewable sources such as · Wind · Solar · Wave and those of non-renewable such as · Natural Gas · Coal · Petrol · Uranium Test 2

Transferring Energy
Students investigate simple energy transfers and depict them as flow diagrams or energy chains. The importance of the sun as the primary source of most energy is discussed. eg Sun à Swamp à Oil Reserve à Service Station à Petrol. Others can be considered, such as: · Sun à Sheep à Meat à Human Exercise · Sun à Clouds à Rainfall à Dams à Hydro Electricity à Sound(Radio) Students should consider a number of similar situations. Test 3 Research Assignment 2

Energy Transformations
Students consider some simple energy conversions from one type of energy to another, such as: · The electric heater- Electrical Energy à Heat Energy · The light globe- Electrical Energy à Heat and Light Energy · Food- Chemical Energy à Mechanical Energy · The door bell- Electrical Energy à Mechanical Energy à Sound Energy Students investigate everyday energy conversions in their home similar to the ones detailed.
