Worksheet 8 can 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 teacher gives the instruction to the students: “Cut out the several parts of the text (and if existing the pictures) and put them into the correct order“. The students work for themselves or together in groups of two.
Solution:
The kinetic energy of the wind iscaptured by a wind power station. |
The wind power station transfers the kinetic energy of the wind into electrical energy. |
The stove transformselectrical energy to thermal energy. |
The thermal energy of the stovehelps the hungry Manuel to cookpasta. |
After eating his noodles, Manuelhas enough energy for a hike. He transforms the energy fromthe food into kinetic energy andclimbs a mountain. |
On top of the mountain Manueldiscovers a toboggan run. While he is tobogganing, Manuel transfers the height energy into kineticenergy. |
When Manuel gets out, henotices that the toboggan mat isvery hot. Through the friction during the tobogganing, the kinetic energy has been transferred into the heat of the mat. |
The results are discussed with the several groups during the work phase and as summary with the whole class.
