The document outlines the steps for carrying out a scientific investigation: 1) Gather ideas and questions, 2) Form a question to investigate, 3) Plan what variable will be changed and what will be measured, 4) Make a prediction about what will happen when the variable is changed, 5) Plan the experiment including materials needed and procedures, 6) Conduct the experiment and record observations, 7) Record results in a table and graph the data, 8) Analyze the results and draw a conclusion.

1. Carrying Out an Investigation
in Science

2. Investigation Steps – Asking a
Question
1. 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.
