3. Identify the improper lab procedure observed in the diagram.
He is not using the wafting technique.
He is drinking a can of soda as he is performing a lab.
The student is yanking the plug out of the electrical socket.

4. Write the PAGE NUMBERS next to each question to help you find the answer.

5. 1. Identify the 1st step of the scientific method in THREE WORDS.
State the PROBLEM
Asking a QUESTION

6. Under what color light will plants grow best?
Problem
Under what color light will plants grow best?

7. 2. Identify the 2nd step of the scientific method.
Do background research
by observing
by studying books, the Internet or other sources

8. 3. Identify the 3rd step of the scientific method.
Form a hypothesis
An educated guess

9. 4. What is the hypothesis based on
4. What is the hypothesis based on? (How do you come up with your hypothesis?)
Background research

10. Research
Plants absorb light to produce their food during photosynthesis.
Plants contain the pigment chlorophyll.
Plants produce sugar (glucose).

11. Hypothesis
I think the plant under green light will grow best because plants are green.

12. 5. Identify the 4th step of the scientific method.
Perform experiments to test the hypothesis.

13. Experiment Each plant is placed under a certain color light.
They will get the same amount of light, & will be watered every 2 days.
Their height will be measured (in centimeters) once a week for 5 weeks.

14. 6. Identify what is tested when performing an experiment.
Hypothesis

15. 7. Identify the 5th step of the scientific method.
Analyze the results of the experiment.
Make observations

16. 8. CIRCLE the choice to identify the meaning of the term analyze in line 8 in the reading.
to ignore
to study closely
to combine
to make

17. Observations B A C D E

23. 9. Identify the 6th step of the scientific method.
Draw a conclusion.
Conclusion = is your hypothesis right or wrong
To conclude = to determine

24. Analayze results 1 2 3 4 5 6 PLANTS Height (cm) Growth of plants 12 108
Height (cm) 6 4 2 1 2 3 4 5 6
PLANTS

25. 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.

26. Steps of the scientific method
Problem
Research
Hypothesis
Experiment
Analyze results
Conclusion

27. Let’s summarize…
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

28. Let’s summarize…
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.

29. Review:
The first step in the scientific method is
to state the problem
experimentation
to state the hypothesis
draw a conclusion

30. When performing an experiment, you are testing the
problem
hypothesis
data
conclusion

31. An educated guess to the problem of an experiment is known as a
variable
theory
hypothesis
law

32. Your hypothesis is based on your
conclusion
data
research
problem

33. Your senses can be used to make a(n)
observation
conclusion
hypothesis
problem
