on DV?
Hypothesis:
If____
then ____
because _____
Materials:
Procedure:
Data:
Ground type:
Temperature trial 1:
Asphalt
Grass
Temperature trial 2:
Average temperature
(from both trials):
Data analysis:
 Are there any
patterns in the
data?
 What may be
the cause of
the patterns
that you
observed?
Why?
 How can the
similarities and
differences in
the data be
explained?
 Based on your
data, why do
you think these
temperature
differences
exist?
 Based on your
data, do you
think the color
of the surface
affects its
temperature?
 Based on your
data, do you
think the type
of surface
affects its
temperature?
 Did you collect
adequate data
to answer the

question, “Do
different
surface
materials have
different
temperatures
during the
same time of
the day? Why
or why not?”
What
additional
information do
you need to
answer the
question?
Construct
questions that
you have and
that still need
to be answered
to answer this
question.
How is the data
collection
limited?
Investigation 2: Urban Heat Island Graph Analysis
Late afternoon
temperature
Rural
Suburban
Residential
Commercial
Down Town
Urban Residential
Park
Suburban
residential
Rural Farmland
1. How does energy warm up materials on the Earth? Include the energy flow
and transfer processes involved.
2. How does the flow of energy change depending on the color of the material?
3. How does the color of a material affects its temperature and why?
4. Based on your data and the reading, draw diagrams that show how energy is
either reflected or absorbed for one dark and one light colored material.
Identify and describe the components in the system and explain the flow of
energy. Describe the similarities and differences between energy flows in the
two diagrams.
5. What is an Urban Heat Island?
6. What causes an urban heat island?
7. What do you think the effects of an urban heat island are on the area and on
people specifically? Why?
8. Are there any trends in the graph/data for the “Sketch of an Urban HeatIsland Profile?”
9. How does the temperature downtown relate to the surrounding areas? What
are the causes behind the higher temperature in the city center? Why? What
are the causes behind the lower temperature around the park? Why?
10. How can humans affect the temperature of different areas? Include ways
that humans can both increase and decrease temperatures.
Investigation 2: Claim - Evidence - Reasoning: Surface Temperatures
State your claim:
How can human activities
affect surface
temperatures?
Provide Evidence:
What data from the
surface temperature
experiments support your
claim?
What information does the
article provide to explain
this phenomenon?
Scientific Reasoning:
How does this evidence
support your claim?

Investigation 3
Reducing the Urban Heat Island - Roof Design Challenge
Problem:
Constraints:
Independent variable:
Dependent variable:
Control:
Step 1: Design
What household/classroom material will you use? What will your design look like?
Step 2: Measuring Outcomes
What outcome do you hope to achieve with your design?
Based on the data you collected in previous investigations, what do you predict will be
the outcome of your design? Why?
How will you measure the effectiveness of your design? What specific results would
make your design successful?
How will you collect data?
Step 3: Data Analysis and Next Steps
Is there a pattern in the data?
What are the limitations of this data? How could you improve your data collection for
future testing?
What is the cause of the pattern observed in the data?
How can the similarities and differences in the data be explained?
Based on your findings, how might you alter your design in order to produce better
results?
