Transcript of Copy of The Scientific Method
2: State the problem as a question:
4:Test the hypothesis with an experiment:
5: Record and organize the data:
3:Form a hypothesis:
6: Analyze the data:
7: Draw conclusions:
Ex: Use all five senses to gather data
Ex: Sight, smell, taste, hearing, and touch
Two types of questions:
- describes characteristics like color, shape, size,.....
- tells how many, how much, or how often. Is described with a number and a unit.
- a possible prediction to the solution for the question or problem.
Ex: A controlled experiment has 3 types of variables and 2 types of groups.
- the variable the experimentor changes on purpose.
Is plotted on the x-axis of a graph.
The variable that responds to the variable that was changed.
- variables kept the same between the 2 groups in a controlled experiment.
- group where one thing is changed.
- group where nothing is changed.
Is used to compare to the experimental group to see if there was a difference between the 2 groups.
Ex: First record data into a data table and then into a graph: a pictorial representation of the data.
- uses columns to compare descriptive data.
Circle graph (pie chart)
- uses percentages to show how a part relates to the whole.
- uses a series of dots connected by a line to show change over time or temperature.
Ex: Check the data to determine trends, patterns or whether or not the data supports the hypothesis.
The conclusions should include:
Ex: Factual results:
summarizes the data and makes comparisons between the experimental group and the control group.
Ex: Support of hypothesis:
State whether or not the data supports the hypothesis and use examples of the data to support the hypothesis.
explains why you think the data turned out the way it did.
record all mistakes so others that repeat your experiment do not make the same mistakes.
tell how to fix any mistakes or tell how to do the experiment better.
Ex: Two new questions:
the questions should lead to a slightly different experiment.
