Steps of the Scientific Method

This Prezi activity will teach students how to properly use the Scientific Method when conducting science experiments. By learning the different steps of the Scientific Method, students will be able to perform experiments just like scientists. (Grade:4)

Transcript of Steps of the Scientific Method

The Scientific Method
Step 1: State the Problem
Step 2:
Gather Information
Step 3:
Form a Hypothesis

Step 5:
Perform Your Experiment
Step 6:
Collect and Analyze Data
Step 7: Draw Conclusions
A hypothesis is a proposition (possible answer) to the question or problem you are investigating. Remember, you must be able to test your hypothesis.
After the experiment is completed explain your results.
Did you answer your question?
Was your hypothesis correct?
Did anything go wrong?
What could you have done to
make your experiment better?
Did you learn anything?
It is important to learn as much as possible about your topic so that you know the best way to conduct the experiment. Collaborate with others and look at the research and data already completed.
Write down the problem you want to solve. Sometimes this is the hardest part!
After you gather data from the experiment,
analyze and interpret the data carefully.
Always think
about how to improve
your experiment.

Step 4:
Design the Procedure for Your Experiment

Think about your procedure carefully. What things could effect your results?
Establish a control group and an experimental group.
Manipulate (change) only one variable when establishing your experimental group.
Try to use quantitative instead of qualitative data.
Present your data in a table and on a graph (if possible).
If you make a graph:
Label the axes
Write a descriptive
title above
the graph
Identify the units used on your graph.
Independent variable (
manipulated variable
The variable that changes between the control group and the experimental group.

Dependent variable (
responding variable
The result that changes in response to the manipulated variable. You usually measure the dependent variable.
Independent variable = x-axis
Dependent variable = y-axis
In "real life" you would now:
Revise your hypothesis and experiment, then try again; or
Have a colleague perform your experiment; or
Publish or present your experiment and data so it can be reviewed by the scientific community.

It doesn't matter
if your hypothesis was wrong. You still learned something.
