The Nature Of Science
What is the definition of science?
The study of the natural world based on facts learned through experiments and observations.
What is the definition of an observation?
To view or notice something in order to gather information.
What is the definition of a hypothesis?
What kind of information goes into your results? How do you present it?
Data you collected in your experiment. It goes in tables/charts and graphs.
What is a cause and effect relationship?
A relationship where one thing happens (the cause) that makes something else happen (the effect).
No!
What is the definition of a scientific question? or How would you describe a scientific question?
A question that can be tested to find an answer that explains your observations.
What is the definition of an experiment?
A scientific procedure to make a discovery, test a hypothesis, or demonstrate a known fact.
What kind of data is quantitative data? What kind of data is qualitative data?
Qualitative – data that is a descriptive group or a category
Quantitative – data that is numbers
In a scientific question, which part is the cause, and which part is the effect?
Part 1 = Cause
Part 2 = Effect
What type of experiment is typically done in nature?
Observational
Does ______part 1______ have an effect on ___part 2________?
What is the definition of a procedure?
A step by step process used to accomplish a specific task or reach a goal
What kind of graph do you make when your dependent variable is percentages or fractions/parts of a whole?
A Pie Graph
What variable is part 2 of a scientific question?
The dependent variable, the effect.
What type of experiment is typically done in a lab setting?
Manipulated
What shouldn't you include in your observations?
Predictions or conclusions!
You don't know the why yet!
What goes into each blank of a hypothesis?
1. Restate/Paraphrase the Scientific Question
2. The independent variable (from the scientific question)
3. The dependent variable (From the scientific question)
What kind of graph do you make when both your independent and dependent variable are quantitative data? What is different about this graph when you compare it to a line graph?
Scatter plot.
You don't connect the dots with a line!
The x axis is a number line, too!
What is the definition of a control variable?
Something that could affect or change the results of your experiment that you don't want to. It is NOT the independent variable - we WANT the independent variable to affect our results - that is what we are testing!
What are the 6 steps of the scientific method in order?
1. Observe
2. Question
3. Hypothesis
4. Experiment
5. Results
6. Conclusions
What three things need to be included in observations?
1. Descriptions using your 5 senses.
2. Questions/Answers that make connections with your mind.
3. A scientific diagram
A part of your experiment used to compare your results to, to make sure there is definitely a relationship between your variables
What do you do in the conclusion section?
Talk about your experiment!
In a scientific experiment, what are we testing?
The relationship between an independent and dependent variable. Does the independent variable actually have an effect on the dependent variable?
