Investigation Steps – Asking a Question
1. Gather ideas
What could we investigate?
What could we measure or observe?
![Page 3: Experiment planning 1](https://reader035.vdocument.in/reader035/viewer/2022081907/544f2762af79593b028b4cd0/html5/thumbnails/3.jpg)
Investigation Steps : Asking a Question
2.Ask yourself what are you trying to find out
You need a question to investigate....
How? What? When?
![Page 4: Experiment planning 1](https://reader035.vdocument.in/reader035/viewer/2022081907/544f2762af79593b028b4cd0/html5/thumbnails/4.jpg)
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)

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.

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.

Investigation Steps: Collecting Evidence
6. Carry out the experiment.
• Note carefully what happens.

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.

Investigation Steps: Recording and Presenting
8. Explain the resultsExplain 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.

SO......How do I carry out an Investigation in Science?
1. Gather ideas
2. Ask yourself what are you trying to find out .
3. Plan what you will change
4. Make a prediction
5. Plan the practical work (Diagram)
6. Carry out the experiment.
6. Record the results
7. Explain the results
