Part of Lesson Plan: Create a Basic Bread Board Parallel Electrical Circuit
Activity Overview / Details
Lesson Three ( A Basic Parallel Circuit)
Students have completed lesson ONE and TWO so they have an understanding of how to build a circuit.
Students can work in teams of two or independently. NO MORE THAN TEAMS OF TWO
Visual Aid: Slide #9 "of the power point "Creating Basic Bread Board Circuits".
Have slide #9 "A Parallel Circuit" up on the screen for everyone to see as they walk in the classroom.
Supplies: Have your supplies out for students to choose what they need to build their series circuit.
Students will need:
1. Their Engineers Notebook
2. Bread Board - plastic or wood (your choice) see lesson ONE of "Creating Basic Bread Board Circuits"
3. Three - 1 inch wide strips of foil, approximently 10 inches long, folded in half length wise (in place of wire)
4. Three - Christmas lights of any kind (small LEDs)
I have the lights cut up into a single light with some of the wire stripped on wither side.
For the Series Circuit they will need two LEDs
5. 14 - 2 inch straws or 14 - 1 inch nails
I had a small plastic block with a grid of holes to work with, so I used split up the middle 2 inch long straws for my posts.
You may need to use the block of wood instead, and use 1 inch nails as posts. Students will pound the nails 1/2 in. into the wood, leaving 1/2 inch or so exposed to wrap the foil around.
If you have to use wood as a bread board you will need a small hammer for students to nail in their posts.
7. AA Battery
Storing materials: In lesson ONE I suggested storing all materials in separate bins. This way students can pull their own materials and also put away their materials. The only product I passed out myself on the second series circuit is the foil, so students don't waste.
