  What is the 1st law of thermodynamics?
• Calorie


  What is a calorie?
• Chemistry – the structure and mechanisms within the atom
• Static electricity


  What causes static electricity to form, and discharge?
• Electrostatic series

  If x rubs against y, what will the charge be?

  How does lightning work?
• Conductor vs insulator


  What is a conductor vs insulator, why does this matter?
• Friction, conduction, induction

  Know the differences between these, and why the differences matter
• Water / humidity on electricity and charge

  What is the effect of water / humidity on electricity and charge? Does water conduct electricity?
• Current electricity


  What is current electricity? How is like our bloodflow?
• Charge balancing when two objects touch / come into close contact

  1. How do electrons move?

  2. How do protons move?

  3. How do I calculate the rough charge of an object?
• Grounding


  • What is? Why is it necessary?
  • How can we use knowledge of it to stay safe.
• Charging objects through induction

  Know the process in both directions – how do we make temporarily / permanently charged negative/positive objects.
• Permanent charge

  What does permanent mean?
• Transmission vs distribution

  1. How does the powergrid work?

  2. How is power generated, and how does it reach your home?

  3. Are powerlines safe to touch?
• Current electricity vs static electricity


  Why do we use current electricity instead of static electricity in our home?
• Conductors and insulators in powergrid

  What are the roles of conductors and insulators in our powergrid?
