Create a list of three
questions that are
good science
questions.

CO2 over time in the Figure in the
article. As close as you can
determine, how much has the
atmospheric CO2 content risen since
1958? Levels are about 400 ppm
now.
Create a list of three
questions that are not
science questions.
What features does a
question need to have
to be a good science
question?

Watch It! Watch It! Why don’t scientists stop with the first step in
the Scientific Method, making observations?

Once they form a hypothesis, what do
scientists do next?
A. Design experiments to test their hypothesis
B. Draw conclusions based on their predictions
C. Compare their hypotheses to other
scientists’
D. Ask the question, “Why?”
Why do scientists write down every detail
of an experiment?
A. Because they do not take any
pictures
B. So they can leave the experiment
alone to run itself
C. Because they always change their
hypothesis
D. So they can do over the experiment
to compare results
What do scientists do when they run
an experiment?
A. Walk away from their experiment
B. Write down their observations
C. Change parts of the experiment
D. Develop a hypothesis
What does it mean to control variables during
your experiment?
A. Keep as many things the same as possible
across the parts of an experiment
B. To use different colored objects for all of the
parts of an experiment
C. To take complete notes about everything
you observe in the experiment
D. To not touch anything once you set up parts

Test it! Start by placing black wool
jackets and white wool jackets into
the closets. Click “TEST” and record
your data after the 5 minute timer
has stopped.
Have you ever wondered whether
light or dark colored clothing would
be more comfortable to wear on a
hot, sunny day? We will be running
a controlled experiment to
determine how color affects heat
absorption. Go to your lab sheet
and write your problem and state
your hypothesis.
Go to the following site to complete the
simulation. Follow the directions on your
task cards! (not supported on mobile
devices)

Now repeat the experiment
for black nylon jackets vs.
white nylon jackets, then
denim with black and
white jackets. Record all
final temperatures in the
data table.

Analyze the data of your
experiment. Draw conclusions and
use Claim, Evidence and
Reasoning to describe your results.
Now, repeat the experiment using two
other colors of your choice. Make sure
you fill in your data table with the
material, colors, and temperatures.
Now repeat the experiment
for black nylon jackets vs.
