ISA - maggots

Today we're going to thinking about ISA topics to do with the practical we just didusing maggots and choice chambers. Answer the following in your books:

1. What else could choice chambers be used for?
2. Why are control variables very important when using choice chambers?
3. Think of another hypothesis you could test using maggots and choice chambers (we already tests whether maggots are affected by light intensity) :
4. Why might it be hard to conclude which conditions insects prefer from this experiment?
5. What is causality? Why is this important in experiments?
6. What is anomalous data? What should you do in a practical if you have an anomaly?
7. We looked at Doctor Wakefield's incorrect claims about autism and the MMR vaccine earlier this year. What has happened recently with measles? Why is interpreting your results correctly important?
8. What did you do with your results to make them more reliable? Why is this a good thing to do?
9. Outline the hazards that are associated with the prac we have done, the risks they create and how you can minimise that risk. You will need to complete a risk assessment in the ISA, so use this table to practice now:

   hazard	risk	safety measures

10. Read these short scetions about scientists getting things wrong, and summarise one. How did they get it wrong in the first place? How was it put right?
11. Extension - Think of a question you would like to answer - it could be anything that relates to your life now or something fairly abstract. How would you go about answering this question? use the steps in the scientific method to write up a plan for this experiment. if anyone comes up with a suitable one for the class we might try it later on.
12. HOMEWORK - Watch this video with the cookie monster (I dont think youtube works at school anymore) and state the pattern they used in the experiment. This is what the girl explains after they have dropped the object in the water.
