Sample Activity of Integration on Excretion in Animals

In Akokoro Village there is a factory that produces sim sim oil. During the production process, the factory releases several waste materials that come out through the chimney, air vents and drainage pipes.
One day, the drainage pipe broke down leading to accumulation of wastes and the factory eventually stopped working. The teacher in a Biology lesson used the scenario of the factory and told the learners that the human body functions in a similar way. The learners, however had difficulty relating the
factory to the human body. Task: Write down a presentation you would give to the learners to help
them understand the analogy.
