Worksheet 8: Mountain hike

WORKSHEET Workshop


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).

Teaching aids:

Worksheet

Procedure:

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.

The concept of energy conversion and any forms of energy that have not been introduced yet are named. In addition, energy forms, which don’t the students known yet, can be introduced with understandable and simple terms. Deviations from the correct order do not affect the development of concepts and the acquisition of terms. They should only be corrected if the promotion of logical reasoning and the recognition of courses of action is to be promoted and is dispensable, especially in the case of impaired pupils. In addition, an incorrect order of the parts can be accepted.
