Walk in silently.
Grab a calculator and any papers for today.
Sit with your House Project Group today!
Silently practice your vocab.
Due Next Class:
•
House Project Check-In #3
Finalized and finished Floor Plan
•
New Vocab
•
Electric Potential Difference (Voltage), V
By the end of the day today,
IWBAT…

Why it matters in LIFE:
Part of being a
functional human
being is being able to
understand what’s
happening in the world
around you!
draw simple circuit
diagrams and indicate the
direction of conventional
current flow.
Why it matters in THIS CLASS:
Our Goal = 80%
Mastering today’s lesson (focused
participation, asking questions, etc)
is the first brick that will help us
reach our goal for this unit, and
eventually for the year
TEKS:
5(C) describe and calculate
how the magnitude of the
electrical force between two
objects depends on their
charges and the distance
between them

•
By the end of today, IWBAT…
draw simple circuit diagrams and
indicate the direction of
conventional current flow.
show how power, current,
potential difference, and
resistance are mathematically
related.
Topic:
Drawing Circuits
LAST CLASS, ELECTRIC POTENTIAL DIFFERENCE
Let’s Experiment!
CLOSED CIRCUIT
A complete and unbroken conducting path
between the source of the current and the
return of the current
OPEN CIRCUIT
A circuit with a switch turned to the “off”
position, or a circuit with any break in it
(electricity cannot travel through an open
circuit)

CURRENT FLOW
EXAMPLE #1
Draw the schematic diagram for the following circuit
Be sure to indicate the direction of current flow!
GP #1
Draw the schematic diagram for the following circuit
Be sure to indicate the direction of current flow!
voltmeter

ROUND!
CIRCUIT STATIONS PRACTICE!
Get with your House Project Group
5 Stations, 2 minutes per station, rotate clockwise
Station Directions – In GP
• Draw the circuit using schematic symbols.
• Indicate whether the circuit is open or closed.
• Indicate the direction of conventional current flow.
HOUSE PROJECT APPLICATION
Stay with your House Project Group
Directions
• Get out your floor plan draft.
• 1 min – Silent brainstorm where you would like to
include a simple circuit (lightbulb, battery, & switch
only)
• 2 min – Discuss and decide with group
• 2 min – Each group member add the simple circuit
schematic to your copy of the floor plan.
INDEPENDENT PRACTICE!
Procedure for IP time:
1)
Silent work time
2) Try and solve without notes first!
Hierarchy of who to ask
1) Your brain
2) Your notes
3) Ms. Kelly (after you #embracethestruggle)
EXIT TICKET
1. Draw the circuit schematic diagram
2. Indicate the direction of conventional current flow
