The steps to the Scientific Method are:

A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment.

For a typical experiment, you should plan to repeat it at least three times (more is better). If you are doing something like growing plants, then you should do the experiment on at least three plants in separate pots (that’s the same as doing the experiment three times).

• 1) Pose a Testable Question.
• 2) Conduct Background Research.
• 3) State your Hypothesis.
• 4) Design Experiment.
• 5) Perform your Experiment.
• 6) Collect Data.
• 7) Draw Conclusions.
• 8) Publish Findings (optional).

The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.

Data Analysis & Graphs

1. Review your data. Try to look at the results of your experiment with a critical eye.
2. Calculate an average for the different trials of your experiment, if appropriate.
3. Make sure to clearly label all tables and graphs.
4. Place your independent variable on the x-axis of your graph and the dependent variable on the y-axis.

Why is the ability to repeat experiments important? Replication lets you see patterns and trends in your results. This is affirmative for your work, making it stronger and better able to support your claims. This helps maintain integrity of data.

Experimental design means creating a set of procedures to test a hypothesis….

1. Step 1: Define your research question and variables. You should begin with a specific research question in mind.
2. Step 2: Write your hypothesis.
3. Step 3: Design your experimental treatments.
4. Step 4: Assign your subjects to treatment groups.

Introduction: How to Conduct Experiments Using the Scientific Method

1. 1) Pose a Testable Question.
2. 2) Conduct Background Research.
3. 3) State your Hypothesis.
4. 4) Design Experiment.
5. 5) Perform your Experiment.
6. 6) Collect Data.
7. 7) Draw Conclusions.
8. 8) Publish Findings (optional).

In a science experiment, only one variable is changed at a time (the independent variable) to test how this changes the dependent variable. The researcher may measure other factors that either remain constant or change during the course of the experiment but are not believed to affect its outcome.
