Circuits

Conceptual resources cultivated:

  • (battery) voltage causes pressure/exerts force on electrons/current
  • more voltage makes electrons move faster
  • voltage is energy per electron/increasing voltage increases electrons’ energy

Learning goals:

  • current is the rate of charge flow per time (dq/dt, in the most formal terms)
  • current flows in complete circuits
  • battery is a variable source of current

Student Feedback

"The sensemaking about circuits assignments taught me a lot because I could experiment with phet and had to explicitly describe what was happening in a circuit and I got really familiar with the concepts."
"The sense-making of circuits assignments were especially helpful and fun for my understanding of circuits and how to create and manipulate them. It was fun building circuits which added to the helpfulness of it."
