    Graphene and Nanotechnology

    Graphene and Nanotechnology

    Overview

    This lesson focuses on graphene including its structure and possible uses and is designed to be used with an Integrated Chemistry and Physics Lesson.

    Standards

    Indiana; ICP.6.2 Explain that, when the charge is transferred from one object to another, the amount lost by one object equals the amount gained by the other, which is consistent with the principle of conservation of charge.

     

    Learning Objectives

     Explain that, when the charge is transferred from one object to another, the amount lost by one object equals the amount gained by the other, which is consistent with the principle of conservation of charge.

    Materials

    Scotch Tape

    Procedure

    Engage:

    1. Students will draw a small picture on the smooth side of a piece of scotch tape using a graphite pencil. They will then describe their observations as they use Scotch tape to remove each layer of their drawing.

    2. Teacher will describe how graphene was discovered.

    Study:

    3.. Show diagram of graphene.

    • How many bonds does each carbon atom make here?
    • How many bonds should carbon be able to make?
    • What does this mean for electrons? (they are able to move freely)

    4. Describe our purpose for using graphene in sensors in my research with gases (to make them very sensitive).

    5. SciShow: Graphene: The Next Big (but Thin) Thing - https://www.youtube.com/watch?v=Mcg9_ML2mXY

    Students take notes on what can graphene do (conductive, strong)

    Activate:

    6. Students can use molecular model kits to put together graphene and show the movement of electrons over the sheet – they need to explain to their partner how this works

    7. Students can use their imagination to design a use for graphene.
