  1. How to write a lab report Mr. Williams – Grade 7/8 Science

  2. Why Write A Lab Report • Over the course of the year we will be doing a number of different experiments. In order to share your results, there needs to be a way of showing your classmates and teachers in an easy to follow format • The following information will be applied to all lab reports • Some lab reports will be shorter than others, but all will have the same components

  3. Components of a lab report • Title • Problem • Hypothesis • Materials • Procedure • Observations/Results • Conclusion

  4. Problem • This is where you state what it is you are trying to find • Here you are posing your question or your purpose of the experiment that you are conducting. • For example: Is aluminum the best metal to use for container ships?

  5. Hypothesis • This is an educated guess as to the outcome of a particular experiment • Here you state what you think is going to happen in your testing…”I hypothesize that…” • The hypothesis does not have to be right! Your experiment will confirm or deny your original expectations

  6. Materials • This is a list of all the items you will need to conduct your experiment. • All items should have their quantities listed as well • For example: • 1 250mL Beaker • 3 Wooden spoons • 2 Stop watches

  7. Procedure • This is a step-by-step way of stating how the experiment is to be performed in order • Other students should be able to follow your plan • The steps should be clear and concise

  8. Observations/Results • What could we measure or observe about the events happening in the experiment • List what you are seeing (smells, sounds, sight) • Here you would put graphs, data tables…etc. Explaining your information.

  9. Conclusion • List what you have found in your observations. • Here you will summarize the results of the experiment and its meaning • List some things that you would change in future experiments to get better results • Did it confirm your hypothesis?
