Grade 8—Procedure Scoring Training
Hot Lamp
Directions: Read the scenario and answer the questions.
Brandi and Jerry did the following controlled experiment to find out how the color of an
object affects its temperature.
Question: What is the effect of different lid colors on the air temperature inside a glass jar
exposed to a lamp?
Hypothesis: The darker the lid color, the greater the increase in air temperature in the
glass jar, because darker colors absorb more energy.
Materials:
glass jar
lamp
four colored lids: black, dark gray, light gray, and white
thermometer
meterstick
stopwatch

Grade 8—Procedure Scoring Training
Procedure:
1. Put the black lid with the attached thermometer on the glass jar.
2. Make sure the starting temperature inside the jar is 24º C.
3. Place lamp 5 centimeters away from the lid and turn on the lamp.
4. After 10 minutes measure the air temperature inside the glass jar and record as Trial 1.
5. Turn off lamp and wait until the air in the jar returns to the starting temperature.
6. Repeat steps 2 through 5 for Trials 2 and 3.
7. Repeat steps 1 through 6 for the dark gray, light gray, and white lids.
8. Calculate and record the average air temperature for each lid color.

Grade 8—Procedure Scoring Training
Plan a controlled experiment to answer the question in the box. In your procedure, you
may use any materials and equipment.
Be sure your procedure includes:
 logical steps to do the experiment


one controlled (kept the same) variable
one manipulated (independent) variable


one responding (dependent) variable
how often measurements should be taken
and recorded
Question: What is the effect of different amounts of water in a jar on the time
for the water to reach 50º C?

Performance Description
Attributes
A 2-point response demonstrates the student understands the Content Standard INQB: Different
kinds of questions suggest different kinds of scientific investigations. Item Specification 1:
Describe a plan to answer a given question for a controlled experiment.
5–6
A 1-point response demonstrates the student has partial understanding of the Content Standard.
3–4
A 0-point response demonstrates the student has little or no understanding of the Content
Standard.
0–2
Attributes of a Procedure
Procedure
Attributes
Description of Attribute
Attributes
One controlled variable is identified or implied in the procedure or the
materials list (e.g., same jar, same lid, same heat source).
1
Manipulated
Variable
Only one manipulated variable (amount of water) is identified or implied
in the procedure or data table (if given).
1
Responding
Variable
The responding variable (time to heat to 50 ºC) is identified or implied in
the procedure or data table (if given).
1
One Controlled
Variable
The procedure states or implies measurements are recorded periodically or
gives a data table.
Record
Measurements
Attribute Notes:
1. If artificial data for the responding variable is given, this attribute cannot be
credited.
2. The phrase take measurement cannot be used to mean record.
1
Trials are
Repeated
More than one trial for all conditions is planned, or implied in a data table,
to measure the responding variable.
1
Logical Steps
The steps of the procedure are detailed enough to repeat the procedure
effectively (examples of illogical steps: no ending time indicated; states
Set up as diagrammed, but diagram is inadequate; recording vague data or
results).

Rubric for: Hot Lamp New Procedure (page 2 of 2)
General Notes:
1. Inappropriate Procedures: If the response does not plan an appropriate procedure for the given
question, the response may not earn any of the possible procedure attributes.
Examples:
a) Repeats the procedure from the scenario
b) Measures only one condition (therefore cannot establish the controlled or manipulated variables)
c) Purposefully changes more than one variable simultaneously
d) Writes a procedure that is too vague to possibly be appropriate
e) Writes a prediction instead of a procedure
2. Naming Attributes: If the response names a bulleted attribute listed after “Be sure your procedure
includes:” without including that attribute in the procedure, the attribute cannot be credited. When a
bulleted attribute is named and implied in the response, both must be correct to be credited.
3. Clarifying Vagueness in Procedures:
a) Vague materials or processes used in the procedure (e.g., add 1 mL) may be credited if the vagueness
is clarified in a materials list (e.g., 1 mL, 2 mL, and 3 mL of water) if given.
b) Measuring a vague parameter (e.g., different amounts of water) may be credited as a manipulated or
responding variable. However, a vague parameter is difficult to repeatedly measure, so the logical
steps attribute cannot be credited.
c) The term “repeat” at the end of a step refers to that step only.
d) The term “repeat” as a separate step (or in a new paragraph) refers to the whole procedure.
e) The term “repeat,” when qualified, cannot be credited for multiple trials (e.g., repeat if necessary,
repeat as desired).
f) A vague action that calls for the manipulated variable to be changed (e.g., add more water) without
indicating how many times, gives no end to the investigation so the logical steps attribute cannot be
credited.
g) NA
h) When a procedure conflicts with a given labeled diagram, the procedure is too illogical to be
effectively repeated. Therefore, the logical steps attribute cannot be credited, but the procedure can be
scored for attributes that are not in conflict.
