What’s My Circuit Scoring Rubric: Codes
(Total Score = 29 points)
Circuit A (Maximum score = 11)
Q1: Observe the bulb in Mystery circuit A (Maximum score = 1)
Code A, B, C, D or Z if blank
Q2: Draw circuit, show path of electricity and label series circuit (Maximum score = 7)
a) Draw (Maximum score = 2)
A = correct 2 battery, 1 bulb series configuration, with wires touching all CCPs
B = correct 2 battery, 1 bulb series configuration, with minor errors, e.g. batteries are reversed or wires don’t touch all CCPs (e.g. wires don’t touch both CCPs on the
bulb). Path must be a complete circle.
C = incorrect series configuration (e.g. 1 battery, 1 bulb) but a complete circuit with all CCPS touching
D = Incorrect series configuration and open circuit
Z = Blank, no drawing, illegible drawing
b) Flow—circuit drawing must show a circular pathway (Maximum score = 2)
A = arrows show a unidirectional flow through the circuit (wires) and through the light bulb
B = arrows show a unidirectional flow through the circuit (e.g. arrows must follow one direction throughout the path)
C = arrows show flow through the light bulb
D = arrows show a multidirectional flow or arrows are incorrect (e.g. arrows on an open circuit) or red pencil flow on an open circuit
E = flow drawn in red pencil through the circuit (wires) and through the light bulb (no arrows)
F = flow drawn in red pencil through the circuit (no arrows)
G = flow drawn in red pencil through the light bulb (no arrows)
Z = Blank, no arrows, no red pencil
c)
Labeling--can get points for labeling even if circuit drawing is incorrect (Maximum score = 3)
A = all CCPs are labeled on battery and bulb and +/- symbols are labeled on all batteries
B = if all CCPs (on batteries and bulbs) are labeled as such
C = if CCPs are labeled only on the battery or bulb and +/- symbols are labeled on the batteries
D = if +/- symbols are labeled on all batteries
E = if CCPs are labeled only on the battery or bulb
F = Labels do not identify the CCPS or +/- signs on the battery (e.g. labels “battery” or “bulb”)
Z = Blank, no labels
Q3: Explain (Maximum score = 3)
A = Comparison to 1 battery and 1 bulb configuration, indicates that the mystery circuit is brighter and provides explicit evidence (e.g. “I compared it to the circuit I
made.”)
B = Comparison to 1 battery and 1 bulb configuration and indicates that the mystery circuit is brighter/has more energy or power.
C = Indicates that two or more batteries results in a brighter (more energy or power) bulb, but does not make a comparison OR explains that the less bulbs in a circuit
results in a brighter bulb.
D = makes a weak reference or comparison to notes from science notebook or journal or a circuit they made, but evidence is not clear.
E = no evidence, insufficient evidence, unclear
Z = Blank, I don’t know

Circuit B (Maximum score = 18)
Q1: Observe the Mystery Circuit (Maximum score = 1)
Code A, B, C, D or Z if blank
***FOR Q2: Score each individual drawing separately and use the same rubric for each drawing***
Q2: Drawings of possible circuits (Maximum score = 7 per drawing, 14 total)
a) Drawings-- must be a circular pathway of equal number of batteries and bulbs (Maximum score = 2 for each drawing, 4 total)
A = correct 1 (2) battery, 1 (2) bulb series configuration, with wires touching all CCPs
B = correct 1 (2) battery, 1 (2) bulb series configuration, with minor errors, e.g. batteries are reversed or wires don’t touch all CCPs (e.g. wires don’t touch both CCPs
on the bulb). Path must be a complete circle.
C = incorrect series configuration (e.g. 1 battery, 2 bulbs) but a complete circuit with all CCPS touching
D = Incorrect series configuration and open circuit
Z = Blank, no drawing, illegible drawing
b) Flow-- circuit drawing must show a circular pathway (Maximum score = 2 for each drawing, 4 total)
A = arrows show a unidirectional flow through the circuit (wires) and through the light bulb
B = arrows show a unidirectional flow through the circuit (e.g. arrows must follow one direction throughout the path)
C = arrows show flow through the light bulb
D = arrows show a multidirectional flow or arrows are incorrect (e.g. arrows on an open circuit) or red pencil flow on an open circuit
E = flow drawn in red pencil through the circuit (wires) and through the light bulb (no arrows)
F = flow drawn in red pencil through the circuit (no arrows)
G = flow drawn in red pencil through the light bulb (no arrows)
Z = Blank, no arrows, no red pencil
c)
Labeling--can get points for labeling even if circuit drawing is incorrect (Maximum score = 3)
A = all CCPs are labeled on battery and bulb and +/- symbols are labeled on all batteries
B = if all CCPs (on batteries and bulbs) are labeled as such
C = if CCPs are labeled only on the battery or bulb and +/- symbols are labeled on the batteries
D = if +/- symbols are labeled on all batteries
E = if CCPs are labeled only on the battery or bulb
F = Labels do not identify the CCPS or +/- signs on the battery (e.g. labels “battery” or “bulb”)
Z = Blank, no labels
Q3: Rule (Maximum Score = 3)
A = indicates: batteries > bulbs, brighter AND bulbs > batteries, dimmer AND when there are equal numbers of bulbs and batteries, the brightness levels will be equal to
each other (i.e. if I have 1 battery and 1 bulb in a circuit, the brightness will be the same as compared to a circuit with 2 batteries and 2 bulbs)
B = indicates: batteries > bulbs, brighter AND bulbs > batteries, dimmer
C = indicates: batteries > bulbs, brighter OR bulbs > batteries, dimmer OR circuits with equal numbers of batteries and bulbs will be equal in brightness
D = not a correct rule
Z =blank
