Lab-Scientific Investigation

Question 0

Step 2 to Scientific Investigation. How, what or why? Must be well defined and testable.

Answer 0

Asking Questions

Question 1

First step of scientific investigation. Scientist try to make observations that are objective and quantifiable whenever possible.

Answer 1

Making Observations

Question 2

Step 3 in Scientific Investigation. Proposing possible explanations. A reasonable explanation to answer the question being asked. Should be testable, falsifiable, and provide educated guess about the relationship of 2 variables

Answer 2

Developing Hypotheses

Question 3

Step 4 to Scientific Investigation. Logical results that are expected in view of the research hypotheses. “If/then” statement. Provide opportunities to test the hypothesis.

Answer 3

Making Predictions

Question 4

Step 5 of the Scientific Investigation. Used to TEST the hypothesis NOT PROVE it.

Answer 4

Experimental Design

Question 5

Step 6 in Scientific Investigation. Organized and summarized data often through data sheets tables and graphs

Answer 5

Presenting the results

Question 6

The factor being manipulated or changed by the researcher

Answer 6

Independent variable

Question 7

The response that is being measured or observed

Answer 7

Dependant variable

Question 8

All other factors that may affect the outcome of the experiment and must be kept constant for all groups

Answer 8

Standardized variables or controlled variables

Question 9

The group subjected to “treatment” or change in the independent variable

Answer 9

Experimental group

Question 10

The group opposite of the experimental group where the results are used to compare to the experimental group

Answer 10

Control group

Question 11

Used to record raw data before it is formatted into tables and or graphs

Answer 11

Data sheets

Question 12

Used to summarize and present results, the actual numbers

Answer 12

Tables

Question 13

Pictorial representations of data which are used to display the patterns or trends in the data

Answer 13

Graphs

Question 14

Graph used for quantitative or continuous data, where both variables are quantitative

Answer 14

Line graphs

Question 15

Graph use for qualitative independent variables and are useful for displaying comparisons

Answer 15

Bar graphs

Question 16

Final step in scientific investigation. The results are examined and used to determine whether the hypothesis is excepted or rejected.

Answer 16

Conclusion

Question 17

A hypothesis that has been tested and repeatedly supported.

Answer 17

Theory

Question 18

Number of times the experiment is repeated.

Answer 18

Replication

Question 19

Appropriate values to use for the independent variable

Answer 19

Level of treatment
