The nature of science
The Scientific Method
![Page 2: The nature of science The Scientific Method. Observation: Gathering information in an orderly way by sight, touch, sound, smell and taste. The band uniforms.](https://reader036.fdocuments.in/reader036/viewer/2022082818/56649f175503460f94c2d3f5/html5/thumbnails/2.jpg)
Observation:
• Gathering information in an orderly way by sight, touch, sound, smell and taste.
The band uniforms are very hot.

Inference:
• Combining what you already know with what you’ve learned to make a logical conclusion. (Assuming)
Maybe the color of the band uniform Has something to do with how hot the uniform gets.

Ask a Question
• Using what you have observed and inferred you ask a question.
Do different colors affect the temperature of the band uniforms?

Hypothesis:
• An educated guess based on facts.
If different colors of fabric are placed in the sun for 10 minutes, then the lighter colors will be cooler.
![Page 6: The nature of science The Scientific Method. Observation: Gathering information in an orderly way by sight, touch, sound, smell and taste. The band uniforms.](https://reader036.fdocuments.in/reader036/viewer/2022082818/56649f175503460f94c2d3f5/html5/thumbnails/6.jpg)
Experiment:
• A test to confirm or disprove your hypothesis.– Control: A Part of the experiment that is not being
tested and is used for comparison.
– Variable: Any part of an experiment that can vary.
I will place thermometers in equal sized black, green, yellow and white fabric pockets for 10 minutes and record the temperatures of each pocket.

• Independent Variable: The part of the experiment that is manipulated or changed by the scientists or person performing the experiment.
I will place thermometers in equal sized black, green, yellow and white fabric pockets for 10 minutes and record the temperatures of each pocket.

• Dependent Variable: The part of the experiment that is affected by the independent variable.

Data
• Information gained from experimental observations and recorded on a table.– Qualitative Data: Description of what the observer
senses. (can vary from one person to the next)– Quantitative Data: Data in the form of numbers.
Temperatures of Heated Fabric
Black 96
Green 94
Yellow 93
White 91

Analyze
• Interpreting the data and creating graphs and charts to look for patterns.
![Page 11: The nature of science The Scientific Method. Observation: Gathering information in an orderly way by sight, touch, sound, smell and taste. The band uniforms.](https://reader036.fdocuments.in/reader036/viewer/2022082818/56649f175503460f94c2d3f5/html5/thumbnails/11.jpg)
Conclusions
• Did the data collected confirm your hypothesis?
The lighter colors proved to be cooler when tested in the sun. Therefore we will make our band uniforms white.

Theory:
• An explanation of an event supported by evidence.

Law:
• A theory that has been tested over time, examined by peer scientists and happens every time.
