Question 34
Figure 1.10 shows the steps that you should follow to plan an investigation. What scientific skills do you need when planning an investigation?
1. Ask a question and make a hypothesis that you will investigate.
2. Identify the variables. Which variables must you keep the same (the control variables)? Which variable will you change (the independent variable)?
3. Decide what you will observe or measure (the dependent variable). How will you collect and record this information?
4. Choose the materials or equipment that you need for the investigation.
5. Decide how you will analyse your data to decide if your hypothesis is correct.
