  2. Conclusion 8.Analysis
20
Q

Variable

A

the factors in an experiment that can be changed to affect the outcome of the experiment

21
Q
  1. Problem
A

the question your experiment will answer

22
Q
  1. Research
A

information you need to help write the hypothesis

23
Q
  1. Hypothesis
A

an educated guess for the answer to the problem. you must tell WHAT you think and WHY!

24
Q
  1. Materials
A

things you need for the experiment

25
Q
  1. Procedure
A

the numbered steps to follow when doing the experiment

26
Q
  1. Data / Observations
A

the information you record while doing the experiment

27
Q
  1. Conclusion
A

the results. use the RACE strategy to Restate and Answer the problem and include data to support your answer (Cite evidence)

28
Q
  1. Analysis
A

use the rest of RACE to Explain what worked well, and what didn’t. how might you change the experiment? why are the results important?

29
Q

5 Golden Rules of Writing a Procedure

A
  1. All steps must be numbered (not bulleted)
  2. The steps must be in order
  3. All steps must be written as complete commands
  4. No more than 2 directions per command
  5. Steps must provide specific mrasurements and amounts

Q

RACE Strategy in Science (Conclusion)

A

Conclusion:
R - Restate the problem
A - Answer the problem
C - Cite data to support answer

31
Q

RACE Strategy in Science (Analysis)

A

Analysis:
E - Evaluate your investigation by…
•explaining the strengths & weaknesses of the experiment & why they are strengths&weaknesses
•explaining what you would change about the experiment & why
•explaining who would care about the results & why
