Objective
By the end of this lesson, you will be able to understand the chemistry behind cars and how different chemical reactions contribute to their functioning.
Materials and Prep
- Paper and pen/pencil
- Internet access for research
- Prior knowledge of basic chemistry concepts (atoms, molecules, chemical reactions)
Activities
-
Research the chemical composition of gasoline and its role in fueling cars. Write a brief summary of your findings.
-
Investigate the chemical reactions that occur in a car battery and how they produce electrical energy. Create a diagram or flowchart to illustrate the process.
-
Explore the role of catalysts in car exhaust systems. Research how catalysts help convert harmful pollutants into less harmful substances. Write a short explanation of this process.
-
Investigate the chemistry behind car paint and its ability to withstand environmental factors. Write a paragraph summarizing your findings.
