Chemistry and physics combine forces to benefit nanofabrications. Learners examine the process of wet etching in nanofabrication. Using corrosive substances such as lemon juice and Coca-Cola, they model the etching process. They then make the connection to how the same process helps to design components in electronics.

Instructional Ideas

• Provide several examples of circuit boards from old electronics
• Create a timeline of the size and capabilities of the circuit boards through the years

Classroom Considerations

• Requires an extensive list of materials; allow time for preparation

Pros

• Emphasizes key scientific vocabulary throughout the lesson
• Gives pupils a strong visual to relate to nanofabrications

Cons

• None
