Worksheet 7.2: Plasticine balls
Teaching aids:
Sufficient plasticine of the same type is required for each group
Procedure:
The teacher asks the class the following question: “What other possibilities are there to let energy act on a plasticine ball?” In the class discussion, suggestions/predictions are collected and written down on the blackboard as individual hypotheses. Then the teacher encourages the students to examine the suggestions in the already existing groups.
Possible solutions:
• To push or step on the ball (conversion of: pressure → deformation energy),
• To throw the ball against a wall (conversion of: kinetic energy → deformation energy),
• To melt the plasticine (conversion of: heat → deformation energy).
All suggestions should be noted and (as far as practicable) tried out. The results are written down to the hypotheses which have been already noted and discussed in class. If possible, the suggestions that have not been tried out will also be discussed.
The aim of this task is to introduce the concept of energy conversion in a two-step approach using the example of the conversion of height energy and other forms of energy to kinetic energy.
