Properly controlled experiment |
In a properly controlled experiment there is a control group which is not exposed to the independent variable, and an experimental group which is exposed to the independent variable. Within the experiment, there should be only one independent variable, so as to keep the experiment controlled. |
|
|
Independent variable |
An independent variable is a variable which is manipulated or changed by the person conducting the experiment. |
|
|
Dependent variable |
A dependent variable is a variable which is observed to see how an independent variable effects it. |
|
|
Properly labeled graph |
A properly labeled graph has the independent variable on the x-axis, the dependent variable on the y-axis, a title which includes both variables, units of measure, and a key if necessary. |
|
|
Control group vs controls/constants |
A control group is an experimental group which is not exposed to the independent variable. A control or constant is a potential variable which is not changed, but is instead kept constant. |
|
|
Qualitative vs quantitative data |
Qualitative data describes the quality of something such as color, texture, shape, smell, or anything else which describes quality. Quantitative data uses a quantity or something measurable such as length, temperature, mass, or anything else that is measurable. |
|
|
What would happen if one of the following happened to a controlled experiment: sample size too small, experiment not repeated, missing a control group, more than one variable, etc. |
The data gathered from the experiment would be inaccurate or unreliable if any of the things listed happened to the experiment. |
|
|
Characteristics of a strong conclusion |
To have a strong conclusion, one must make sure to: not have first person, state the purpose of the lab, include procedures, include claim evidence and reasoning, identify sources of error, and connect it to course content. |
|
|
Hypothesis vs theory vs law |
A hypothesis is a prediction of the outcome of a certain set of circumstances or of an experiment. A scientific theory is a generally accepted explanation that has been shown through multiple experiments and observations, but has not been completely proven A scientific law is an explanation that has been tested and proven to be true. |
|
|
How science is effected by society |
Certain possible advancements in science can be hindered by society, such as when the heliocentric theory for the universe first came out, and it went against the generally accepted geocentric theory. People tend to stick to what is generally accepted and not look into new possibilities if they go against what society holds to be true. |

Traits of a good scientist |
Skeptical: don't believe in just anything Objective: look at the facts, not how people feel about it Open minded: open to new ideas and possibilities Creative: willing to try new things or look at things in different ways when getting an unexpected outcome |
