Wednesday, 3/1 2:35-3:45
Choose a Topic
Pick a topic that:
Will be interesting.
You will be able to complete in the required
time.
Question
After narrowing down your topic, choose a
testable question.
Example: How does caffeine affect the growth
of a plant?
Research
Develop 2-3 questions that you want to answer
about your topic.
Try to use various sources for your research.
Example: What do plants need to survive? How does
caffeine affect plants? Do all plants need the same
amount of water?
Research should be designed to get background
information about your topic, before you begin
your experiment.
Hypothesis
Make your guess
Use your research to make an educated guess about
how you think your experiment will turn out.
Use the “ If __________ then I think _____” format
Example: If I pour 100ml of coffee on four pea plants and pour
100ml of water in another four pea plants, then I think the
plants with coffee will grow taller because caffeine will
stimulate the plants.
Materials
Make a complete list of everything
you will use in your experiment.
Tell how many and how much of
each object used.
Use metric measures only.
Procedure
Design your experiment
Design your experiment so that you are only testing for one thing.
Make sure that you do the same things to all groups of objects being
tested.
Example: If you are testing plants:
Use the same seeds. (CONTROLLED/CONSTANT VARIABLE)
Plant all of them with the same soil. (CONTROLLED/CONSTANT
VARIABLE)
Put them all in the same amount of light for the same amount of time.
(CONTROLLED/CONSTANT VARIABLE)
The only thing that should be different about the plants is that one
received coffee and the other water. (INDEPENDENT VARIABLE)
Procedure
Write down step-by-step directions on how
to do your experiment:
Do not leave anything out!
Use multiple trials (At least three.)
1.Get 8 pea plants (100 cm tall).
2.Place 4 pea plants on each tray.
3.Label one set of plants “Caffeine”.
4.Label the second set “Water”.
5.Pour 100ml of coffee (with caffeine) onto the soil of each
plant on the caffeine tray twice a week.
6.Pour 100ml of water onto the soil of each plant on the
water tray twice a week.
7.Measure each plant with a metric ruler.
8.Record data in record book.
Procedure
Example:
Do your experiment.
Have fun!
Collect, Record, and Display Data
Record observational and/or measurable data in a table
Take Pictures and/or print pictures that go with your
experiment
Choose the correct graphs for your measurable data.
Bar-comparison
Pie-percentage
Line-change/time
Results
Explain the data exactly as your charts/
graphs/observations show in paragraph form
Example:
From reading my charts and graphs, I know that
Plant Group #1 grew an average of 40cm with
100ml of coffee. Plant Group #2 grew and average
of 20cm with 100ml of water.
Conclusion
Tell what the outcome was (consider your original question)
Include if your hypothesis was supported or not
(Be sure to use the term “ My hypothesis was/was not
supported”)
Think of something you could do differently next time
(What variable you would change if you could do the experiment
again?)
Conclusion
Example:
The Plant Group that was given coffee grew 20cm more on the
average than the Plant Group that was given water. My hypothesis
was supported since the plants that were watered with coffee
(caffeine) grew taller than those that were given water. Therefore,
caffeine has a positive effect on the growth of pea plants. This may
be due the fact that caffeine is a stimulant. The caffeine could have
stimulated the plant to grow. If I could do this experiment again,
the variable I would change would be the amount of caffeine I
would place in each plant group. I would use 50ml for plant group
#1, 100ml for plant group #2, and 150ml for plant group #3.
