  2. How does temperature affect the germination of seeds? GROUP ACTIVITY: Write a hypothesis for this experiment Method: • Place a piece of filter paper at the bottom of each petri dish (prepare 5 dishes) • Place 10 seeds on each filter paper • Soak each filter paper with distilled water • Leave in a dark cupboard for 24 hours at different temperatures • Count the number of seeds that have germinated • Work out the percentage germination of seeds • Repeat the experiment • Calculate the mean

  3. 1) Write down how well you think the experiment went and why…. “The experiment was easy to set up but the results obtained did not fit in with the original hypothesis….

  4. 2) State whether what you found out agrees with your hypothesis or not. "The results that were obtained for 0°C, 15°C and 30°C, support the hypothesis. The hypothesis stated that …"

  5. 3) Point out any odd results that you had. "Looking at the graph /standard deviations anomalous results can be identified. These are….”

  6. 4) Explain why IN DETAIL, you may have some odd results / what problems you had with the experiment. Include a MINIMUM of THREE errors and they MUST refer back to the method "One of the reasons that these large standard deviations/anomalous results were obtained could be due to not using the same type of seed consistently. The effect of this could have been……"

  7. 5) Explain how you could improve the experiment if you had to do it again IN DETAIL. Suggest AT LEAST THREE things. Include a diagram and explain why. "The experiment could be repeated using just cress seeds as these have a germination time of just 24 hours which allows results to collected quickly and the experiment to repeated easily".

  8. 6) Explain what further experiments you could do in the future, if you had the time. "If this investigation could be extended, the effect of volume of water on the percentage germination would compliment the data obtained in this experiment. It would allow optimum temperatures and water volume to be determined for seed germination. This could be done by…"

  9. 6 STEPS TO EVALUATION SUCCESS! • Write down how well you think the experiment went and why…. 2) State whether what you found out agrees with your prediction or not. 3) Point out any odd results that you had. 4) Explain why IN DETAIL, you may have some odd results / what problems you had with the experiment. Include MINIMUM THREE and it MUST refer back to the method 5) Explain how you could improve the experiment if you had to do it again IN DETAIL. Suggest AT LEAST THREE things. Include a diagram and explain why. 6) Explain what further experiments you could do in the future, if you had the time.

  10. Group task • Write an evaluation as a group for this experiment • Swap your evaluation with another group • Using the IA checklist, mark off ALL points in the evaluation that cover Aspect 2 of Conclusion And Evaluation 4. Write in any corrections/missing statements
