1. Identify the 1st step of the
scientific method in THREE WORDS.
• State the PROBLEM
• Asking a QUESTION
Problem
Under what color light will
plants grow best?
2. Identify the 2nd step of the
scientific method.
• Do background research
- by observing
- by studying books, the Internet or other
sources
3. Identify the 3rd step of the
scientific method.
• Form a hypothesis
–An educated guess
4. What is the hypothesis based on?
(How do you come up with your
hypothesis?
• Background research
Research
• Plants absorb light to produce
their food during
photosynthesis.
• Plants contain the pigment
chlorophyll.
• Plants produce sugar
(glucose).
Hypothesis
I think the plant under green
light will grow best because
plants are green.
5. Identify the 4th step of the
scientific method.
• Perform experiments to test the
hypothesis.
Experiment
1. Grow the plants for 5 weeks.
2. Each is placed under a certain color light.
3. They will get the same amount of light, & will
be watered every 2 days.
4. Their height will be measured (in centimeters)
once a week.
6. Identify what is tested when
performing an experiment.
• Hypothesis
7. Identify the 5th step of the
scientific method.
• Analyze the results of the experiment.
8. CIRCLE the choice to identify the
meaning of the term analyze in line 8
in the reading.

7. Identify the 5th step of the

9. Identify the 6th step of the
scientific method.
• Draw a conclusion.
What does the conclusion state?
• Was your hypothesis right or wrong?
• Did the experiment disprove the
hypothesis?
• Did the hypothesis match the results
of the experiment?

Conclusion
My hypothesis was wrong. Plants grow best
under blue light, not green light. The plant
under blue light grew 11cm while the plant
under green light grew only 2 cm.

6. Conclusion
Let’s summarize…
1. List the steps of the scientific method.
Problem, Research, Hypothesis, Experiment, Analyze data, Conclusion
2. Explain the difference between the problem and the
hypothesis.
The problem is the question and the hypothesis is your educated guess.
3. What are you testing when performing an experiment?
The hypothesis
4. What is used to make observations?
5 senses – sight, hearing, touch, taste, smell
5. Describe an example of an observation.
His shirt is blue. It is hot in the room. The substance smells like banana.
6. Identify what the conclusion states.
Whether your hypothesis is correct or incorrect.
Review:
