This resource includes a highly visual PowerPoint presentation (over 90 slides!) on the topic of ENERGY, forms of energy, energy transformations and energy diagrams. The presentation uses many visual aids and is thoughtfully animated to promote participation from learners of all abilities.
Two worksheets and sample exam questions (71 questions with ANSWERS!)) are also included. Appropriate for year 7 or year 8 pupils.
Students will learn:
1. that energy is the capacity or ability to do work (the ability to make matter change)
2. that generally, there are 2 types of energy: potential energy and kinetic energy
3. that there are many forms of potential and kinetic energy including: thermal energy (heat), electromagnetic energy (radiated), sound energy, gravitational potential energy (GPE), elastic potential, nuclear, chemical energy and electrical energy.
4. that gravitational energy depends on an object's mass and height above the earth's surface
5. that kinetic energy depends on an object's mass and how fast it is moving
6. that energy is transformed from one form to another
7. that a fuel is stored energy, which must be burnt to release the energy
8. Fuel + Oxygen = Energy + Carbon Dioxide + Water + Waste Product
9. that most of the Earth's energy ultimately comes from the Sun
10. that energy sources can be described as either renewable or Non-renewable
11. that Renewable means can be used again or replaced within a Iifetime
12. some advantages and disadvantages of energy sources
13. the need for energy saving with non-renewable energy sources and ultimately with all energy sources
14. to construct an energy transfer diagram
15. to construct a Sankey diagram
16. that energy is conserved in an energy transformation
