NITROGEN NEEDS LAB REPORT Lab Report Format Title:(the name of the lab or experiment) I. Purpose/Problem/Question: The purpose or problem states the reason(s) why you are doing the experiment. Write down exactly the problem that will be investigated or experimented. Sometimes it is the question you are asking or investigating. II. Introduction/Research/Background Knowledge: In a few words tell what you already know or have found about the problem that will let you make an educated guess. This is your background information from the text, teacher, or other sources. It gives the reader an understanding of what you know about the experiment or subject. III. Hypothesis: What do you expect to find? The hypothesis can be stated as “I think …..”. This is an educatedguess on the outcome of the experiment based on your previous experiences and observations and your background knowledge. The hypothesis does not have to guess the correct outcome, but the experiment must be set up to test the hypothesis.
IV. Materials/Supplies: This is a list of all equipment and chemicals used to do the experiment. Please include quantities (amounts). V. Procedure: The procedure tells exactly what you did. Make statements in the past tense. Be specific. The procedure you use affects the results. So, it is important to be accurate in explaining what you did. Using clear paragraphs or numbers or bullets explain all steps in order they actually happened. If you have done this section correctly, another researcher should be able to duplicate your experiment.
VI. Data and Analysis (Observations) · Data: The observations tell exactly what happened when you did the lab. An observation is measurable information that comes to you through your senses. Results include data in the form of well-labeled tables, graphs, drawings and other observations. Place your observations and data in this section without discussion or comment. This is where you include any calculations made during the experiment · Analysis: Discuss what the data shows. You should not try to explain the results or data just state what they show. VII. Conclusion/Summary: Conclusions explain your observations and describe how your data relates to the problem. 1. Restate the purpose/problem: Tell why you did this experiment and what you hope to find out. 2. Restate your procedures and analysis: Explain in your own words what you did and found out or discovered. Include things that happened that differed from the procedure section. 3. Restate your hypothesis: state whether or not the data supports your hypothesis. Use the analysis. 4. Errors: Talk about the errors that might have affected the results. What might have affected the results? 5. New experiment: How would you improve the experiment or correct the errors next time. Make it better? How can you improve the experiment? 6. Real World Connection: What does this have to do with the real world? Connect the small experiment with larger ideas. Why did we do this experiment? What does it tell us about the world around us?
