Transcript of Energy Types

Objectives:
Know and recognise different types of energy
Understand energy transfer diagrams

Energy
PLTS
Creative Thinkers - making connections
Independent Enquirers - reasoning

Energy cannot be created or destroyed,
but it can be transferred from one type
to another
Around the room are various objects.
Types of energy
Task: state which energy type each is designed to give out
What energy transfers are taking place here?
A few easy ways to show what is happening for the lamp:
Energy Transfers
electrical energy light + thermal (heat) energy
electrical lamp light + thermal
or a Sankey diagram
Draw energy transfers for a radio
Your turn
How well has your partner achieved the following:
Peer Assessment
Chemical potential sound + kinetic + thermal + light
Radio
Chemical potential radio sound + kinetic + thermal + light
An easy way to see how the energy is divided up, no matter how complex the system
Sankey Diagrams
Which is best at producing light?
Comparing light bulbs
Marking your partner's work
Peer Assessment
2 x www what have they done particularly well?
Make sure you express your thoughts in full sentences
2 x ebi what do they need to do to raise the standard of their work? Again, use full sentences.
Look critically at your work and read your partner's comments.
Write a sentence or two to explain how you can close the gap, so that next time your work is of a higher standard.
Self-assessment
How good is the Sankey diagram? Does it include all the types of energy?
Old style light bulb with a filament
New style CFL energy saving bulb
Types of Energy
Electrical
Light
Sound
Kinetic (movement)
Thermal (heat)
Gravitational potential
Chemical potential
Elastic potential
