  1. Biology IA

    Bio IA about how cooking affects vit c concentration in brocoli
  2. Practice Bio IA - Effect of icnreasing conc. of H2O2 on the activity of catalase

    practice bio IA done in my first year of IB. this was kind of lacking in detail but I think (if I remember correctly) this was at least 17/24 marks. the experimentation wasn't that vigorous as it was just a practice! 
  3. Checklist for Biology IA-HL

    This is a handy checklist to use while writing your Bio HL IA. It has all those small detail that you may easily gain marks from putting in your IA. 
  4. a2 biology coursework

    i did this for the a2 biology coursework, thought it might help students doing ias on ecology 
  5. 1. El crecimiento de la célula y sus factores determinantes .pdf

    In spanish a lab that explains why the size of the cells
    Mod note to viewers: Please remember NOT to "borrow" anything from this file. IB is very strict about plagiarism.
  6. Effect of Temperature on Enzyme Activity of Catalase

    A design lab that I did towards the end of last year for biology; our objective was to investigate a factor that affected the enzyme activity of catalase. I chose temperature as my factor of study, and I used two sources of catalase: beef liver and potato catalase. My design lab was given an IB 6 by my biology teacher, so it was only marked internally.
  7. Photosynthesis Lab Report

    The following is a draft/idea for a Biology IA. It has been created along with an IB examiner and focusses on the investigation if Carbon Dioxide is necessary for Photosynthesis.
  8. Factors affecting enzyme activity - Biology HL IA

    Received a 7 for this IA.
  9. Homeostasis - Biology HL IA

    Received 17/18 I believe.
  10. 3 labs - level 6

    My friend's biology labs, I have permission to upload them here. She recieved 36/48, giving her level 6.
  11. Leaf size investigation

    Leaf size investigation practical done during a biology field trip. Grade: D pcc 5, DCP pcp 4, CE cpp 4... (ps my bio group got downgraded 5 points), so dont trust the grading..
  12. Rate of Photosynthesis IA

    Experiment measuring rate of photosynthesis
  13. IB Biology Sample IA Marked By IB

    Design 5
    Data Collection And Processing 6
    Conclusion and Evaluation 5
  14. Transpiration Design Lab

    Transpiration Design Lab for Biology

    Lab: Investigating the effect of SA:V on rate of diffusion in agar cubes.
    There are somethings I didn't do, which are included here:
    Writing a good lab report
  24. [Full]Plant transpiration

    Lab: Transpiration lab, by the use of Vaseline on either sides of a leaf.
    There are somethings I didn't do, which are included here:
    Writing a good lab report
  25. [Design]Effect of pH on amylase activity

    Design of a lab investigating the effect of pH on activity of amylase.
    There are somethings I didn't do, which are included here:
    Writing a good lab report
