Purpose of the lab or the question to
be answered during the lab is clearly
identified and stated.
Hypothesized relationship between
the variables and the predicted results
is clear and reasonable based on what
has been studied and the information
collected
provided
All
members
documentations that are labeled
properly and clearly show the actual
significant parts of the experiment; it
provides evidences that the members
followed
&
performed
the
experiment; supports data and results
All members showed all appropriate
evidences.
Contain sufficient
information to be understood outside
of the report. Draws attention to
trends or major findings.
Purpose of the lab or the question to
be answered during the lab is partially
identified – vague.
Hypothesized relationship between
the variables and the predicted results
is reasonable based on general
knowledge and observations
Provides meaningful interpretation
of results. Scientific concepts are
well explained. All scientific terms
are used accurately and appropriately
Conclusion includes a summary of
the experiment, whether the findings
supported the hypothesis, possible
sources of error, and what was
learned from the experiment
Answers are logical and has a
scientific and fully substantial
explanation. Students demonstrate an
accurate understanding of the
scientific concepts; Questions are
answered completely. Errors if any
are minimal
3 or more group members
were able to successfully
perform and gather data
3 members provided documentations
partially
show
significant
performances of the members;
provides selected evidences and
partially supports the groups' data and
results
3 members showed sufficient data.
Evidences present but might not be
stand-alone.
(1-5) or
(1-4)
Purpose of the lab or the question
to be answered during the lab is
erroneous or irrelevant.
Hypothesized
relationship
between the variables and the
predicted results has been stated,
but appears to be based on flawed
logic
Only 1-2 members provided
pictures; documentation is limited;
it hardly shows evidence of
members' participation and are
very limited to support the groups'
data and results
1-2 members reported pertinent
data collected during the
experiment. Evidences may have
been omitted.
Provides some interpretation of
results. Described some of the major
scientific concepts, and may have
left out some key background
information.
Conclusion includes a general
overview of the experiment and what
was learned from the experiment;
“something is missing”
Interpretation of results is not
clearly explained. Several of the
major concepts are inaccurately
described or missing, and/or the
results are misinterpreted.
Conclusion shows little effort and
reflection; “a lot is missing”
Answers are logical and has some
scientific explanation. Students have
basic knowledge of content, but may
lack some understanding of some
scientific concepts. Questions are
answered fairly well
Answers
lack
scientific
explanation. Students appear to
have not fully grasped the lab
content; the answers are so
incomplete and/or so inaccurate
1-2 members were able to
successfully perform and gather data
Only 1 member performed the
experiment and gathered data

I.OBJECTIVES:
At the end of the experiment, we would be able to:
1. measure the velocity of a pulse (transverse) traveling through a slinky spring
2. find ways of altering the wave velocity of a pulse (transverse) in the same spring as in part I
3. investigate how the diameter of a slinky spring will affect the velocity of a pulse (transverse)
traveling along with it.

4.
5.
What three variables are kept constant
Identify the dependent variable being measured.
What factors affect the speed of the wave
If the distance of the wave is increased, what will the effect to the speed?
If the time of wave gravel is decreased, what happened to the speed?
Page | 4 jrs/egt/rls_gr10sci_ustjhs_ investigating waves
Part II
1.
How will the change in the amplitude affects the speed of the wave or pulse?
2.
If the spring is stretched to a smaller distance, how would it affect the speed of the
wave?
Part III
1. Will the speed of the wave or pulse be affected by the size or thickness of the slinky? Why
or why not?
2. Which will have a faster speed between a short and thick slinky and long and thin slinky?
Prove your answer.
VIII.. CONCLUSION: (as a group)
IX. APPLICATIONS:(AS A GROUP)

1. IT IS IMPORTANT THAT THE GROUP PROVIDES THE INFORMATION ON THE PERCENTAGE
DISTRIBUTION OF TASKS. IF THE TASKS WERE DIVIDED EQUALLY AMONG MEMBERS,
(e.g. 4 Members) THEN, EACH MUST HAVE 25% AS THEIR TASK INDICATOR WHICH MEANS
ALL WILL GET THE SAME TOTAL SCORE OF THE ACTIVITY.
2. OTHERWISE, THE LOWER % WILL BE DIVIDED BY THE HIGHEST % . EACH QUOTIENT
RANGE SHOWN BELOW WILL BE EQUIVALENT TO POINTS DEDUCTED FROM THE TOTAL
SCORE OF THE ACT.
