Energy Transfers (flows)

Comprehension and additional task exercises pages 118 and 121 from Next Page Science KS3 Complete. Accompanying PowerPoint and word searches available for** free** from the website.
This exercise covers:
• Ways that energy can flow: electric currents, changes in position speed or vibrations, progress of chemical reactions, flow of heat and radiation
• Examples emphasising which store decreases and which store increases, to include: a torch, a dropped object, a stretched elastic band released, raising objects, plants growing, a bicycle at constant speed and speeding up, a bullet fired from a gun and a screaming child
• An exercise matching energy flows to examples
• Exercises recognising which energy store is increasing and decreasing
• Practise drawing energy transfers using arrows with guidance from previous examples
• An exercise recognising amounts of energies in ‘everyday’ examples
• Amazing WHAT? facts
