  1. How to Write a Lab Report

  2. Average Grades 2009 Average: 57 Highest: 73 Lowest: 43

  3. Common Errors • Do not use 1st person (I, we, you, your, etc) • Use “the scientist”, “the group”, “the students”, etc • Do not use contractions (I’m, We’re, etc) • Do not end a sentence with “etc.” • If you did not know something, do not write “I do not know”. Either get the results, or come and talk to the teacher to figure it out!

  4. Title Page • Every lab should have this! • It should have the title in the middle. • The title should be relevant to what was happening in the lab. • It should not just say “Enzyme Lab” • Be more specific

  5. Abstract • This should come after the title page! • It needs to include: • What the overall purpose of the lab is • What was being tested in the lab • What the results showed • Do not include the procedure, step by step, here

  6. Introduction • Include the following: • What is the lab about? • What are the functions of enzymes? • How to enzymes react to different things? • What enzyme is this lab talking about? • Your Hypothesis!

  7. Hypothesis • This should include: • What you think is going to happen in EACH part of the lab. • You need an overall hypothesis or educated guess of how an enzyme is going to react!!! • Do not write “I think….”

  8. Materials • List these out! It’s okay to make them bulleted! • Include approximately how much or how many you used of each material • If you have a recipe with out the exact measurements of each substance, your food is not going to turn out right!!!

  9. Methods • This should read like a recipe that a 6 year old can follow. • Pretend that your teacher has never done or read this lab when you write these up. • If you write the procedure from the lab, make sure to take out the questions in the paragraphs! • Do NOT write your results in this section!

  10. Results • You must have FIGURES and WRITING!!! • Figures can be charts or graphs. • Observations – what you see. Do not just write a reaction rate. You teacher does not know what this means! • Explain exactly what you are seeing! • Writing – You must write your results in a paragraph! write exactly what is in your charts. • Do not explain it or give reasons why you think something happened! • Ex. The catalase enzyme in the HCl solution had a very low reaction rate. It did not bubble as much as the catalase enzyme in the water and hydrogen peroxide.

  11. Discussion • Include all of the following: • Did you accept or reject your hypothesis – re-state your hypothesis. • Why did you get the results you got • Ex. Why do you think the catalase enzyme reacted the way it did with the HCl solution? • What follow-up experiments could you do? Form a questions to ask and to follow up with. • What went wrong – what could you have done wrong? Ex. Measurements, length of time potatoes were in each solution, different people doing different things…etc
