Investigation Steps : Asking a Question 2. Ask yourself what are you trying to find out You need a question to investigate. . How? What? When?

Investigation Steps: Choosing what to change (making a fair test) 3. Plan what you

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

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

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

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 results Explain what your results show.

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.
