ISA research sheets

For the ISA next year, you will be given a sheet and a hypothesis to investigate. The hypothesis for this investigation is

'How much vitamin C is in food depends upon the time the food is cooked for.'

You should write this word for word into the box on your sheet.  Once you have done this, there are a few other sections.
Research sources:
Give the name of two books or websites you have used to do some background research for the practical, so that people could find them with the details you give. It would also be sensible to write a note reminding yourself what you get from each website. You can try this one, this one or find other information on your own.
Method:
This is where you need to write the steps that you will take in your practical to get your results. make sure you include as much detail as you can and don't miss any steps!
Equipment:
You need to produce a list of all the equipment you will need. Include amounts and numbers of things.
Risk assessment:
For the risk assessment, you need to think of things that could go wrong and what problems they would cause. If you can also think of ways to stop these things happening, put them in too.
Context:
For this section, you need to think of people or groups who would be interested in your experiment. list them and explain why they would want to know the results from your experiment.

Remember, you can take the sheet into the exam with you so including things like the independent and dependent variables, blank tables to record your results (with units in titles) and any other information that might help you is a good idea. Section 1 is basically re-writing this paper for marks so you're helping yourself do better later on!

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.
