Why is it important to control the variable in an experiment?

Biology
1 answer:
goblinko [34]3 years ago
8 0
If you do not control the variable in an experiment, you cannot have a reliable result. For instance if you are performing an experiment on how a certain plant grows with soda vs water, you cant put one plant in the fridge and one outside in the sun, as you do not know whether or not the different temperatures are affected your results. The variables are not controlled so you cannot know if the results are accurate.

What are the keys to a strong lab procedure?​
Natali5045456 [20]

Answer:

Purpose: A brief description of why the experiment is being performed. Include details about the experiment, such as the methods used, a specific chemical reaction(s), and/or anticipated product.

Hypothesis: Provide a statement or two about the anticipated outcome of the experiment.

Experimental Procedure: A step-by-step description of the experiment including the chemicals, equipment, and/or methods used. Complete sentences must be used for the description. DO NOT simply copy the procedure from a lab manual or a handout. Condense the given procedure into steps so that you can understand and follow them.

Laboratory Safety: Give a complete, descriptive listing of the safety precautions, hazards, or other safety procedures that are needed for this experiment.

Experimental Data: Record all data resulting from the experiment in your laboratory notebook. The experimental data should be recorded in tabular form. Do not record your experimental data in your laboratory manual.

Observations: This section is used to record any qualitative observations and notes on the changes to the experimental procedure. Sudden bursts of scientific insight or other information during the experiment that may aid in the interpretation of the data generated are to be entered in this section. No points will be awarded when the observations are recorded outside of the laboratory. It is also important that you record your unknown number in this section of your notebook.

Calculations: Present outcome/summary of data analysis using tables, Excel graphs, and/or figures. List separately all pertinent mathematical equations followed by a sample calculation for each. Use the recorded data from the experiment when performing the calculations.

Results/Discussion: Questions that should be addressed in this section may include: Did the experiment work, and if not, why not? Were the results obtained in the experiment those expected based on the laboratory procedure? If the experiment was to be repeated, what improvements would be made? What types of errors occurred and how could they be corrected? How did the observations play a role in the outcome of the experiment? When applicable, you should compare your experimental value(s) to that of a published, literature value(s), commenting on the accuracy of your technique.

Conclusion: Summarize the findings of the experiment, which must include the final results of the experiment, e.g., the percent yield of a reaction, the identity of an unknown, etc. Look back at the purpose and hypothesis of your experiment and assess whether or not you met your goal in performing the experiment.

References: Include all pertinent information such as, your laboratory manual, textbooks, web sites, and any other library resources used in the preparation of your laboratory report.
