8 ORGANISMS REQUIRE A SUPPLY OF ENERGY AND MATERIALS FOR WHICH THEY OFTEN DEPEND ON, OR COMPETE WITH, OTHER ORGANISMS

Task 7

WORKSHEET

Materials and tools for a working group:

  • worksheets

In this task, pupils focus on exploring where one takes energy, respectively, whether he takes energy from the sun, just like plants. Due to more suitable conditions for a verification process, we recommend to carry out the activity in spring / summer months.  

At the beginning, the teacher gives pupils worksheets with a picture of concept cartoons © called Sunbathing. The task of the pupils will be to think about the statement. Finally they should agree with one of them and justify their choice. If they disagree with all statement, they can create their own. The teacher discusses the particular statements with the pupils and asks them to justify why and on what basis they (dis) agree with which statement: What do you think about the statements of the characters shown in the picture? Do you agree with them? If yes / no, why? Which statement do you think is right / wrong? Why?

They may indicate their predictions by indicating the person in the image they agree with. After making the predictions, the teacher asks the pupils to think out how they could verify their choices (statements).

Pic 108: Sunbathing

When sunbathing, we cannot use the energy from the sun as plants do. The sun raises the temperature of our skin. Our body responds to this by starting to sweat more to cool the body. One needs to receive energy from food.

The situation can be verified by staying in the direct sun. Raising the skin temperature can be felt by the pupils themselves. If they stayed in the sun for a long time, another effect is a change in skin color – tan.
