Reflection: Connection to Prior Knowledge What Is Pollution Anyway? - Section 2: Accessing Prior Knowledge


I shared the photographs of polluted areas to assess student prior knowledge of pollution. I did not tell students that was what they were looking for. They could have talked about the ocean or the city or the river, but right away students picked up on the pollution in the pictures. They noticed the trash on the beach, the smoke in the sky and the oily look of the river. One of the students mentioned the term pollution and another asked what pollution is.

I let the students respond to one another. A student defined pollution as trash on the ground and someone else added that it is dirty smoke from factories. Another student added that it is when people dump stuff out of their car window. Their definitions showed a good awareness of what pollution is so I knew that I could go forward with the lesson as planned.
