The EIE Curriculum

Students think like environmental engineers as they review a mural of a small American community, noting possible sources of pollution and suggesting ways to clean up or eliminate the source of the pollution.

Reflection Questions

Where in the video do you see Kathryn reinforcing the distinction between artificial and natural forms of pollution?

Kathryn distinguishes natural and artificial contaminates throughout the lesson, including when students observe dirty water in a bottle and look for pollution in the schoolyard.

  • Kathryn first describes the two types of contaminants as she reviews the storybook. (1:21)  
  • Kathryn prepared a bottle of dirty water for students to observe. When naming items they see in the water, she asks them to it identify the items as artificial or natural contaminants. (1:49)
  • As part of the activity, students use red and green crayons to circle any artificial or natural contaminants they find in the picture. (3:45)
  • In the iPad extension activity, students are again asked to identify items they find as either artificial or natural contaminants. (7:57)

What are some of the benefits of including the iPad activity as part of this lesson?

The iPad activity allows students to apply what they have learned in a local environment while developing their technological literacy skills.

  • By looking closely at their schoolyard, students can see that environmental contaminants can be found all around, including in their local environment. (7:49)
  • By taking digital pictures and using the device to highlight items in red or green, students gain and/or apply new technology skills. (7:56)
  • Any opportunity for students to get outside during the school day is a bonus! (7:40)
