- Slide 2
- The research question is the most important part of scientific
inquiry. Your experiment is done to answer this question. Make sure
you question can be measured quantitatively, rather than
qualitatively.
- Slide 3
- Use a variety of resources to research your topic. Research
will help you learn about techniques and equipment that can help
you carry out your experiment.
- Slide 4
- A hypothesis is an educated guess about the outcome of your
experiment. Your hypothesis will be based on your previous
knowledge and the information you obtained during your research.
Your hypothesis should be stated clearly so it can be easily test
and answer.
- Slide 5
- Design an experiment to test your hypothesis. It must be
designed so that you can collect the best data possible to prove or
disprove your hypothesis. Remember to be carefully of all the
different variables involved in the experiment you must only change
one thing at a time an keep other things constant. It is best to
perform the experiment more than once.
- Slide 6
- Collect data. Make notes of your observations (examples include
tables, measurements, graphs etc...). Analyze your data and make
conclusions to answer your initial question. The conclusion is a
summary of your research and the results of the experiment.
- Slide 7
- Write a report to communicate your results from your experiment
to others. You will be completing lab reports.
- Slide 8
- Suppose you notice that Mr. Kennedys tomoatoes are much larger
than Mrs. Spicers. You wonder why?.
- Slide 9
- Is there something in a tomatoe plants environment that makes
it grown bigger tomatoes?
- Slide 10
- Visit your local library, check out the internet etc... You may
discover that tomato plans have certain requirement, such as water,
sun, fertilizer etc... that will impact the plants ability to grow
large tomatoes.
- Slide 11
- Mr. Kennedys tomatoes grew larger because he used a
fertilizer.
- Slide 12
- You decide to conduct an experiment in which you change only
one variable the use of fertilizer (this is the independent
variable). Your dependent variable will be the size of your
tomatoes. You will control the amount of sunlight, and the amount
of water.
- Slide 13
- For a month, you take daily measurements of the size of the
tomatoes, and also record the number of colour of the tomatoes.
After a month, you conclude that the tomatoes grown in the
fertilizer were significantally larger.
