STEPS TO EXPERIMENTS
 

1. Chemists design experiments to test their hypotheses.
    

2. It is important to have a clear hypothesis before designing an experiment.
    

3. The hypothesis should be specific and testable.
    

4. Identify the important variables and control all the variables except for one.
    

5. Use standard procedures and repeat the experiment multiple times to ensure reproducibility.
    

6. Analyze the data carefully and draw conclusions that are supported by the data.
