Science In Action

Question 0

Independent (Manipulated) Variable

Answer 0

Changed by experimenter, ONLY 1

Question 1

Hypothesis

Answer 1

Guess/prediction, what you think

Question 2

Dependent Variable

Answer 2

Changes in response to IV, you observe/measure to collect data

Question 3

Constant

Answer 3

Remains the same throughout the experiment to prevent affecting the outcome

Question 4

Control

Answer 4

Standard of comparison, in “natural” state

Question 5

Conclusion

Answer 5

Interpretation of observation & data

Question 6

6 things to consider when designing a good experiment

Answer 6

1) Procedure
2) List of equipment
3) Repeated trials (2-3xs)
4) Hypothesis/knowledge
5) Variables- IV,DV,Constant
6) ONLY 1 IV

Question 7

3 essential parts of a good procedure

Answer 7

1) Safety
2) Step by step (#d list)
3) Clear directions

Question 8

Data Tables

Answer 8

Title w/ IV & DV
Neat (ruler)
IV left column, DV w/ diff trials next, calculated (avgs.) right
Labels/units

Question 9

Graphing

Answer 9

IV x-axis & DV y-axis
Title x VS. y-axis
Label/(units)
Range=L-S, /# of intervals, round up if needed, mark every 5
Direct x & y increase Inverse x increase y decrease
Line of “best-fit” 1/2 & 1/2
Slope=y2-y1/x2-x1, not data points, draw box, add units, write relationship
