Experiment planning 1

  1. 1. Carrying Out an Investigation in Science
  2. 2. Investigation Steps – Asking a Question 1. Gather ideas What could we investigate? What could we measure or observe?
  3. 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. 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. 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. 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. 7. Investigation Steps: Collecting Evidence 6. Carry out the experiment. • Note carefully what happens.
  8. 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. 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.
  10. 10. 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
