Week beginning 11 May
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…
Syllabus
To prepare for paper 1Complete 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.
BU2.5
Fatigue
CRN sheet
Context – copy on
How athletic training can reduce the likelihood of fatigue.
Q1 A Good Hypothesis
Include a bit of Science
What are your independent and dependent variables?
Q1 Hypothesis - how to get 3 marks (write your own on CRN sheet now)
• Hypothesis:• 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)
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
Q2 Possible research sources
10 minutes to look around lab – Website print http://www.myscience8.com/human_biology/module_3/muscle_fatigue_labs_form.pdf http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/respiration/respirationrev4.shtml
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
Q3 – Method (write on sheet)
Includes:
1. Equipment list2. How equipment is
used3. Measurements
you will make (your variables…)
4. How you will make it a fair test
5. 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?
Q4 is always variable, be prepared
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?1. Correct clear headings headings – independent
then dependent variable2. All units for relevant variables3. 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
Bring a
black pen, pencil,
ruler and calculator
