The activity shows cellular respiration in its role of breaking down carbohydrates generated by the sun’s energy. Hydrogen atoms previously bound in carbohydrates are newly connected to the oxygen released from water during photosynthesis. This makes it possible for breathing organisms to use the stored solar energy.
The building block makes it clear that animals and humans are dependent on the oxygen in the atmosphere generated by plants and that all biomass in circulation is generated by organisms, which carry out photosynthesis.
By acting out the biochemical processes using people and ordinary materials the concepts become more easily understandable. The transfer, separation and joining of the balls and fruits make the substance flow tangible and understandable. The rules of the game are based on its biochemical foundation and therefore also convey information on chemistry.
A ball game with movement is a fun and unique way of conveying knowledge.
- Balls with Velcro: oxygen, hydrogen, carbon dioxide
Description of application during the course
- The acting exercise can be used in all lectures in which cellular respiration, carbon cycles, oxygen cycles, or the sun’s energy as a universal energy source are central topics.
- The scene can be acted without knowing more than the basic equation: the theoretical background of the „rules of the game“ can also be explained to help increase understanding of the biochemistry of cellular respiration in breaking down carbohydrates.
Aha effect for students
- Life can not exist without the sun
- Life on Earth is a material and energy flow
- Without plants there would not exist oxygen
This building block can be combined with the building block Acting Out Photosynthesis as a Ball Game.
