Science and Engineering Flashcards
Observation
Using your five senses to gather information about something.
Quantitative Observation
Using numbers or measurements to describe something.
Examples:
- 10 meters
- 450 milliliters
- 176 grams
Hypothesis
A prediction based on prior knowledge. Always written in an if then statement.
Example: IF I put the ice cube in the sun, THEN the ice cube will melt.
Variable
Any factor that can be manipulated, controlled for, or measured in an experiment.
Inference
An explanation to an observation based on prior knowledge.
Control Variable
What must stay the same in the experiment.
Manipulated/ Independent Variable
The thing that you are testing or changing in an experiment and it is graphed on the X-axis.
Dependent/ Responding Variable
What you are measuring or observing in an experiment and it is graphed on the Y-axis.
Claim
Is the answer to the question you are trying to answer.
Evidence
Scientific data that supports your claim.
Reasoning
The how or why the evidence supports our claim; scientific rule.
Conclusion
A written summary of an experiment that uses evidence to prove what you learned.
Qualitative Observation
Using your senses to describe the characteristics of an object-color, texture, taste. Examples: - Smooth texture -Brightly colored -Smells bad
