Jeremy decides to cook some pasta noodles. He notices that the directions say to add salt to the water before
bringing the water to a boil. The next day, Jeremy asks his science teacher, Ms. Jackson, a question: “How does
adding salt affect the boiling temperature of water?” Of course, Ms. Jackson asks Jeremy to plan and conduct an
experiment to find the answer.
9. What was the control set-up for Jeremy’s experiment?
a. One quart of boiling water with salt added
b. One quart of boiling water with no salt added
c. One quart of room temperature water with salt added
d. One quart of room temperature water with no salt added

1000
100ml graduated cylinder
It is based on 10
A hypothesis
Gram
It stays the same throughout the experiment, it is what you compare your results to.
Tested by experiments, is an educated guess about the outcome, can only be written when you know a little bit
about the experiment.
Scientific method
One quart of boiling water with no salt added
A question
The true scientific method does not have a specific order or series of steps, instead it continually doubles back on
itself and repeats itself.
If, then statement
Independent variable
Dependent variable
A factor or factors that are kept the same throughout all parts of the experiment are often called control variables
or control sets.
Y=mx+b
M = slope, x = what is on the x axis
Atmospheric CO2 at Mauna Loa Observatory
Years or time
Dependant variable
Since 1960 the amount of CO2 in the atmosphere has been steadily increasing
330 parts per million
A perfect straight line
You consider all the data for the x axis and y axis
Slope = Y2 – Y1
X2 – X1
