Carrying Out an Investigation in Science
2
Investigation Steps Asking a Question

• Gather ideas
• What could we investigate?
• What could we measure or observe?

3
Investigation Steps Asking a Question

• 2.Ask yourself what are you trying to find out
• You need a question to investigate....
• How? What? When?

4
Investigation Steps Choosing what to change
(making a fair test)

• 3. Plan what you will change
• What will you change? (only
• ONE thing)
• what will you measure?
• what will you keep the same?
• (The things which could change are called
  variables)

5
Investigation Steps Making a Prediction

• 4. Make a prediction
• (A Prediction is often known as a Hypothesis)
• What do you think will happen to the variable you
  are measuring or observing........ when you
  change the variable you are interested in.

6
Investigation Steps Planning the Enquiry

• 5. Plan the practical work
• How will you carry out the experiment? What will
  you do?
• Design the experiment.
• List what you need.
• Describe how you will use the equipment. Make a
  diagram if you want.

7
Investigation Steps Collecting Evidence

• 6. Carry out the experiment.
• Note carefully what happens.

8
Investigation Steps Recording and Presenting

• 7. Record the results
• Produce a table of results.
• The table includes the independent variable (what
  you were changing) and the dependent variable
  (what you were measuring).
• Use the results table to help
• you construct a bar chart or
• graph of your results.

9
Investigation Steps Recording and Presenting

• 8. Explain the results
• Explain what your results show.
• Decide whether your prediction was correct.
• Make a conclusion about what you have found out
  and explain it clearly.
• Make a note of things you might change if you
  were to do the enquiry again.
• Report back to the rest of the class.
