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
