Week beginning 11 May

4. Your problem:
Investigate a factor that may affect how quickly muscles become fatigued What factors do you know that affect how fast a muscle becomes fatigued? What theory do you know to support your ideas…

5. Syllabus

6. To prepare for paper 1 Complete candidate research notes
– BUT NOT as a draft!
Bring to next lesson
– write this in your diaries now!
If you have extra time in exams – let us know now.

7. CRN sheet
Fatigue
BU2.5

8. Context – copy on
How athletic training can reduce the likelihood of fatigue.

9. Q1 A Good Hypothesis What are your independent
and dependent variables?
Include a bit of Science

10. Q1 Hypothesis - how to get 3 marks (write your own on CRN sheet now)
I think that if I change the light intensity, the rate of photosynthesis will change (1)
Explanation:
Unclear – I think this is because photosynthesis uses light (1)
Clear – Increasing light intensity increases the amount of energy available for chlorophyll to absorb for photosynthesis (2)

11. Q2 Research Sources (write on)
Name 2 sources (book or internet) – which is more useful and why?
Can I access your sources? Can an examiner access your sources?
e.g. “I used wikipedia” = 0 marks
Internet needs to be typed in to find the webpage
Books need title / author or editor AND PAGE

12. Q2 Possible research sources
10 minutes to look around lab –
Website print
AQA text book
Would these sources get full marks?
You need two sources clearly identified, say which source is most useful for your plan and give reasons why.
DO NOT USE CHEAT WEBSITES AS A REFERENCE

13. Q3 – Method (write on sheet)
Includes:
Equipment list
How equipment is used
Measurements you will make (your variables…)
How you will make it a fair test
Risk assessment (what is the safety??)
3 is it better to have a continuous or categoric independent variable? What is the range of your independent variable? How will you know if this range is suitable at the end of the experiment? What is the interval of the independent variable? How will you measure your dependent variable? 4 What control variables are needed for a fair test?

14. Q4 is always variable, be prepared

15. Q5 Your Blank Table
In the ISA you will get 2 marks for drawing a blank table to record your results in.
What should you ALWAYS ensure you include?
Correct clear headings headings – independent then dependent variable
All units for relevant variables
Repeats and means not needed
I should be able to look only at your table and know exactly what you are investigating without reading anything else at all

16. Bring a black pen, pencil, ruler and calculator
