Midterm Questions Review
• We will look at the midterm questions about
the scientific method and go over the correct
answers. We are doing this to review the
scientific method so you don’t make as many
mistakes on the final test in May.
• Get out a piece of notebook paper. Each
person at your table needs a piece of paper.
Make your paper look like the one below.

9. Why is the following hypothesis considered a bad
hypothesis? “Plants that are not given fertilizer will grow
taller.”
a) It doesn’t have “if” and “then”.
b) The prediction is wrong.
c) The independent and dependent variables are in the wrong
order.
d) This is a good hypothesis.
10. De’Lon wants to know if students do better on their
homework if they listen to classical music or hip hop music.
What is the independent variable in this experiment?
a) Students’ grades on homework
b) The age of the students
c) The volume of the music
d) The type of music
11. Which is the example of a qualitative
observation?
A) It is going to rain later today.
B) The clouds are dark gray.
C) The temperature is 67 degrees Fahrenheit.
D) All of the above.
12. Which is the example of a quantitative
observation?
A) It is going to rain later today.
B) The clouds are dark gray.
C) The temperature is 67 degrees Fahrenheit.
D) All of the above.
13. What is the main reason why scientists have
constants?
A) So scientists know that their results came only from
the independent variable and nothing else
B) So scientists stay safe
C) So scientists can record data easier
D) So the experiment is clear and easy to understand
14. Identify a constant in this experiment: “Do
plants grow faster in the shade?”
A) Amount of shade
B) How fast the plants grow
C) The amount of water each plant gets
D) All of the above are constants
• Make sure your name is on your paper and
hand it in to the tray.
• Open your lab book to the “Scientific Method
Review Sheet” from last week. If you don’t
have this sheet, write on the next blank page
of your lab book or on a piece of notebook
paper.
• Together we will create an experiment about
whether Nikes or Jordans will make you run
faster.
Step 1: make an observation and ask a
question about it.
What is an observation you could make about
shoes if you were in track?
-Some people in track wear Nikes and some
wear Jordans.
What question could you ask about Nikes and
Jordans?
-Do Nikes or Jordans make you run faster?
Write this on your paper.
Step 1:
-Observation: Some people in track wear Nikes
and some wear Jordans.
-Question: Do Nikes or Jordans make you run
faster?
Step 2: Research if needed
What do I already know about this?
What can I do to learn more?
Write this on your paper.
Step 2:
-Research: Observe the runners, research online,
talk to shoe salesmen, ect
Step 3: Make a hypothesis
Identify your independent variable:
-Nikes and Jordans
Identify your dependent variable:
-speed
Write your prediction about which shoe will
make you run faster. Remember the If/then
format and that what you change goes before
what you measure.
Write this on your paper.
Step 3:
-IV: Nikes and Jordans
-DV: speed
-Hypothesis: If you wear Nikes, then you will run
faster.
Step 4: Test the hypothesis in an
experiment
• How will we test this?
• How many times should we test this?
• What are some constants we should have?
Write this and finish it on your paper.
Make sure you have details explaining
exactly what you will do.
Step 4:
-These are the steps I will take to test my
hypothesis: …
-Some constants I will have include:
• Step 5: Record and analyze the data
• Step 6: Write a conclusion to sum up the
results
The last two steps of the scientific method
would be done if you actually did this lab.

• Follow the directions given by your teacher.

Measurement Review
Page
Today’s Plan
• Review measurement together
• Complete the length, mass, and volume labs
• Homework tonight!
Write the red info in your lab books
Metric Units
• Kilo, Hecto, Deca, Base (grams, meters, liters),
Deci, Ceni, Milli
NOT Metric
• Miles, pounds, inches, feet, ounces
• In science we do not use these units. Science
always uses the metric system.
• Metric length smallest to largest:
– Millimeter (mm) width of a period
– Centimeter (cm) width of your fingernail
– Meter (m) width of your table
– Kilometer (km) distance between Rogers and the
University
• Meters = length
• Grams = mass (the amount of stuff in
something)
• Liters = volume (how much space something
takes up)
Other hints:
• When measuring with a ruler, measure
starting at the first line (not the edge of the
ruler).
• When measuring volume in a graduated
cylinder, get at eyelevel with the liquid and
read the bottom of the curve.
• Complete the Length, Mass, and Volume labs
with a partner. You can have up to 3 people in
your group. You must be on task or you risk
being separated.
• Hand in your paper if/when you finish and
begin your homework. Homework is due on
Monday.
