Systems and Scale | Community Connections: Activity 1


1. Introduce students to uses of combustion in their community.

Have students read the Worksheet introduction and answer the questions in section I.A. For question 1, it may help students to draw the structure of methane (a central carbon bonded to 4 hydrogen atoms). Discuss their answers. Focus on their precision of language. Their word choice should not imply that energy is being used up during combustion. Rather energy is changing forms.

Have students answer questions 2 and 3 to the best of their ability.

Homework: Have students talk with family members to make sure their list is complete and accurate.
