  1. Success Criteria for writing a experiment report!

  2. What should a scientific report include? • Title • Hypothesis • Variables • Equipment • Safety • Method • Results • Conclusion • Extension

  3. Designing a Title • A good title should relate to what your experiment is all about. It must be informative. Here are some examples: • To investigate the conversion of chemical energy into heat energy in food. • To test electrical conduction of a variety of materials • An analysis of the different factors needed for the germination of seeds • Examining the effects of weight of a skateboard on the distance it travels

  4. Writing a Hypothesis • The purpose of the hypothesis is to tell your reader what you predict will be the result of the experiment ( what you think will happen) • Remember to give a reason behind your prediction.

  5. Hypothesis Which one of these could you use to start your hypothesis? I think… We believe…. The hypothesis is… Our researchers believe…

  6. How to write the – Hypothesis The hypothesis is……. Good ‘The hypothesis is that the cotton will keep the water warmer for longer than the other materials.’ Excellent ‘The hypothesis is that the cotton will be the most effective insulator and will therefore be the material that keeps the water warmer for longer than the other materials.’

  7. Variables • A variable is any factor that can be changed measured or controlled in an experiment eg. Measurements, temperature, speed, time etc.

  8. 3 Types of variables • Independent variable: A variable that you change • Dependent variable: is a variable that changes as a result. • Controlled variable: all other variables that are kept the same

  9. How to display your list of equipment • The purpose of writing the ‘list of equipment’ section of a scientific report is to tell the reader exactly what is needed to conduct the experiment. • This section is displayed as a list that shows the quantity of the materials and objects you need and the specific details and measurements of these objects. (the details are put in brackets) Remember to make sure you write the quantity first! For example: 5 x glass beaker (900ml) 5 x Thermometer 2.5l hot water

  10. How to write the – Safety Precaution • This section needs to list all of the things that might cause harm to people during the experiment. Make sure the container holding the boiling water is kept on a flat surface. Keep water away from electric sockets. Don’t place experiment containers in a place where they can be knocked over. Wear eye goggles. Ensure lab coats are worn. * Refer to safety PowerPoint for a list of possible safety concerns in the lab

  11. The Method • The method is a list of step by step instructions to tell your reader exactly what to do / exactly what you did! • Ask yourself if I gave this method to someone else could they follow it exactly without your help or advice? (replicate it)

  12. Success Criteria for a good method

  13. The Results Section • The results are a representation of what data you collected. • Your raw data can be presented in a table…..

  14. The Results Section • Your data must then be represented in a graph. • It’s important that you pick the most suitable graph for your data. • There are many different types of graphs such as line graphs, bar charts and pie charts. *Line graph if numbers on both axes * Bar graph if numbers on one, words on the other

  15. What should a good graph look like?

  16. Success Criteria for graph Drawings Each tick is worth 1 Point: 1-3=Level 1 4-5= Level 2 6-7=Level 3

  17. How to write an Evaluation • Tell the reader a summary of the results • Suggest reasons for the results of the experiment. • Your conclusion should also include if the hypothesis was correct or not. • For Example: • Our results indicate that… • This statement supports/ rejects my original hypothesis

  18. How to write the extensions/Evaluation • What problems did you face? • How could the investigation be improved? • How could you extend this investigation further from what you have learned? • E.g. A problem that I encountered during the experiment was that… • To improve the experiment in the future I would do this differently…… • To extend this experiment I would compare/look at more/……
