Observation
• Using your senses to study the world

Problem Statement
• Question that scientists are wanting to answer with an experiment.
Helpful hints when writing a problem statement:– Must be in question form– Must include IV and

Hypothesis
• Proposed answer to a scientific question.• Hypothesis Must Haves:– Testable and Specific– Take If.. IV then …DV

Practice writing Hypothesis

Experiment
• Testing the hypothesis• Must be repeated• Include independent and dependent variables.– Only one variable tested(keep constants)

Independent Variable
• Condition that is manipulated, or changed, by a scientist

Dependent Variable
• Observed and measured during an experiment.

Constant
• Conditions that do not change during an experiment.

Identify the Independent and Dependent Variables
1. What effect does food color have on the amount of food fish eat?
IV=DV=

Valid Experiments
• Two groups are required:– Control – standard for comparison– Experimental – group that receives the
independent variable
![Page 17: Scientific Method Processing Skills. Observation Using your senses to study the world.](https://reader033.fdocuments.in/reader033/viewer/2022052420/5a4d1b827f8b9ab0599bb609/html5/thumbnails/17.jpg)
Observations can be recorded as DATA
• Qualitative: include sights, sounds and smells.
• Reports what happens
• Quantitative: can be measured or counted. EX: mass, volume, temperature.
• Explore how something happens

DATA
• Must be organized into charts, tables, or graphs
![Page 19: Scientific Method Processing Skills. Observation Using your senses to study the world.](https://reader033.fdocuments.in/reader033/viewer/2022052420/5a4d1b827f8b9ab0599bb609/html5/thumbnails/19.jpg)
Communication/Conclusion
• Answer to the hypothesis based on data obtained in experiment.
• Scientist shares the analysis of data and experiment.
• Other scientist review experiment
