# Lesson: T-Gem and Simple Circuits

Objective: Students will be able to construct simple circuits, as well as identify the equipment needed to do so.

Materials: Computer lab, wires, light bulbs, batteries, switches.

Class Activity:

• Students prior knowledge will be assessed informally through a class discussion. What di students know about circuits; can they give any examples.  How do circuits behave.
• Have students create circuits using phet.
• Have students do the same process using the actual materials given to them.
• What happens when the switch is open? Closed?
• Try creating circuits with multiple switches and light bulbs.
• Have students create various circuits given varying numbers of switches and light bulbs.
• Extension: Explain to students the difference between a series circuit and a parallel circuit, have students create both and explain the difference to each other.

Haneefa,

You have sketched out the elements of a simple circuits plan using PheT. The Finkelstein reading may be of further interest here and depending on the age level of students, there may be particular student conceptions to be aware of around electric current. The prior assessment of their knowledge is in line with constructivist thinking about how one constructs understanding. In a TELE, it might also be interesting to think about how students might be able to make their thinking visible and Explain to classmates the difference between a series circuit and a parallel circuit before creating both. I look forward to the development of your integrated plan!
