Worksheet 9can be used for deepening and extension after different forms of energy and the concept of energy conversion have been developed (e.g. worksheets 5-7).
Worksheet
The students work for themselves or together in groups of two. The teacher gives the following instruction: “What belongs to what? Link the boxes that belong together!“
Car engine | Fuel → explosion → movement |
Light bulb | Electricity (electrical energy) → light + heat |
Solar collector | Solar radiation (solar energy) → heat (thermal energy) |
Photosynthesis | Solar radiation (solar energy) → sugar (chemical energy) |
Solar cell |
Solar radiation (solar energy) → electricity |
Accumulator |
Electricity → chemical energy |
Fluorescent lamp |
Electricity (electrical energy) → light |
Kettle |
Electricity → heat |
Electric motor |
Electricity → movement |
Battery |
Chemical energy → electricity |
Firefly |
Chemical energy → light |
Match |
Chemical energy → light + hea |
Walking person |
Chemical energy → movement |
(eletric) Generator |
Movement → electricity |
Brakes |
Movement → heat |
The results are discussed with the several groups during the work phase and as summary with the whole class
The pupils are asked: “Do you know any other energy converters? What types of energy do they convert?” The suggestions are collected, discussed and made visible on the blackboard or similar
