possible topics to research
Possible topics to research
  • Write down a few things that interest you.
  • Make a list of ideas you have for your research topic. You can use ideas from previous slides, from brainstorming or try going to http://www.csiro.au/resources/ps1z1.html

For a video clip and more ideas to get you started.

decide on your problem to solve
Decide on your problem to solve!
  • What are you actually going to do?
  • What are you going to find out?
  • What measurements and observations will you need to take?
  • What results do you expect to obtain?
  • Which factors will affect the results?
your experiment
Your Experiment
  • The hypothesis is an educated guess about what you think will happen in a certain set of circumstances or conditions.
  • You will need to decide on what the conditions are.
  • Keep as many factors the same as possible, so that the results can be clearly interpreted.
equipment
Equipment
  • Decide on the equipment that you are going to use and the method you that you will use.
  • You may need to borrow or build equipment ( or use equipment in another facility).
the variables factors that could change during the experiment
The Variables- factors that could change during the experiment.
  • For your experiment to be a fair test, as many variables as possible are kept the same, while you change only one particular variable.
  • In this way you can sort out which change lead to the results that you obtained.
slide11

The independent variable is what you deliberately change. It is what you are testing.

  • The dependent variable is what changes as a result. This must be measurable.
accuracy
Accuracy
  • When making measurements, you need to be careful to ensure that they are as accurate as possible.
  • Measuring carefully, reduces errors.
slide13

Repeating an experiment more than once, will give you confidence in your results.

  • You need to repeat the experiment until you get consistent results.
  • Scientists then average these to get an answer to their question.
slide14
All measuring instruments have their limits. A wooden ruler has an accuracy of 1mm, so the most accurate a reading could be, would be to the nearest 0.5mm. You cannot use 3.42685cm !
keeping a log
Keeping a log.
  • Record your hypothesis, aim, equipment list, method, diagrams of equipment, results, research and all other work and problems in a book, NOT on scraps of paper. Photographs are easy.
slide16

We have emailed a sample book to you at your DET address.

  • Print it out and put it into a folder.
  • This needs to be handed in to your teacher for checking.
  • Also include the date and time spent on each activity. Depending on your project, you might also include weather conditions, time etc.
remember
Remember
  • Experiments usually don’t work the first time.
  • Modify.
  • Alter equipment, solutions etc.
  • Record alterations, problems, how they were overcome.
  • Repeat your experiment.
  • Do the work yourself. Please discuss your research freely, ask advice, find answers BUT do the work yourself.
recording results
Recording Results.
  • Photographs?
  • Can you tabulate, graph, diagram, spreadsheet?
  • Get creative!
  • Look at the results: what do they mean? Do you need to modify? Are the results unexpected? Have you repeated your experiment enough times?
reflection
Reflection
  • Work through your results to see if they support your hypothesis or not. Do you need to do more experimenting?
  • The final part of the project involves a discussion of results. Describe difficulties you encountered and how they were overcome. Include suggestions for further improvement.
  • Write a conclusion, based on the results you got and your hypothesis.
acknowledgments
Acknowledgments
  • It is important to acknowledge any help you had from friends, teachers, parents, mentors etc.
  • Include a bibliography, include websites, books, experts in the field, anything or one that gave you ideas or help.
