  1. Chemistry Lab Data

    This is a series of lab data of Hess's Law Lab
  2. Practice Chemistry IA (analysis and eval only) - Order Determination

    "What is the order of reaction of hydrochloric acid (HCl) in the reaction between marble chips and HCl?" was my research question. this was a really straightforward practical because it was just for practice, and our teacher only got us to do the analysis and evaluation section, marking the whole thing out of 12 (this scored a 10/12)
  3. Chemistry IA

    Chemistry internal assessment. Received level 7
  4. Chem IA

    This is a Chemistry IA
  5. Enthalpy change for khco3 decomposition

    this is a sample IA including the conclusion and evaluation
  6. IA Topic 5- Enthalpy change of KHCO3 Decomposition

    In this file it includes a pracitice IA for the conclusion and analysis of the Enthalpy Change of KHCO3 Decomposition.
  7. Conservation of Mass in Copper Reactions

    This lab investigates the strengths and weaknesses of experimental procedure. By holding the law of conservation of mass to be true, the experimental results show exactly how much error the procedure caused. In the IA rubric of analysis and evaluation, the report scored 5 and 6 respectively, for a total of 11/12.
  8. 22/24 Marks Practice Chemistry IA on Ethanoic acid in vinegar

    This is an IA I did for HL Chem in DP1, we were pretty much given the topic and I don't think it would be enough for a final IA, but my teacher said it was probably the best she read. I can't remember where I lost the two marks but the main issue with the assignment was that I didn't really have a literature value to compare to, or a scatter graph (which my school requires).

  10. Chemistry HL IA Level 7 (23/24) – 2017 Syllabi

    My Chemistry HL IA focusing on mathematical kinetics with an unexpected twist. Score breakdown are as follows:
    Personal Engagement: 2/2
    Exploration: 6/6
    Analysis: 6/6
    Evaluation: 6/6
    Communication: 3/4
    Total: 23/24 (7)
    Personal proudest written work from high school. 
  11. Chemistry IA 22/24

    Testing the concentration of ethanoic acid in vinegar comparing colored and colorless vinegar. 
  12. IA (DCP+CE) Determining Molar Volume of Hydrogen gas

    This is my DCP+CE Practical Design determining the volume of Molar Volume of hydrogen gas.
    This has not been graded by the IBO. However, my teacher has given me good remarks about it.
    The document is in a pdf form to discourage plagiarism.
    Feel free to leave any comments or advice. I am constantly trying to improve my IA writing skills

  13. DCP and CE Gas Laws Lab

    5 and 6. Pretty good lab.
  14. Aspirin LAB

    Aspirin LAB, done in chemistry HL as part of option meds and drugs. Enjoyed a good grade.
  15. Factors affecting the rate of reaction

    Received 18/18 for this IA and a chemistry internal assessment score of 48/48 as moderated by the IB.
  16. A factor influencing the solubility of a salt

    Received 18/18 for this IA and a moderated mark of 48/48 by the IB.
  17. Hess' Law Practical

    A practise IA that I did for chemistry
    my teacher gave it full marks for CE and DCP
  18. Sample IA lab

    Sample IA lab - received a 6
  19. Chemistry design lab - IBO Sample

    Factors affecting light absorbed by transition metal. Sample produced by the IBO as chemistry teacher support material.
  20. BMI vs. Fitness Graph

    BMI vs. Fitness Graph
  21. Fluctuations in Deer Populations Numbers

    Fluctuations in Deer Populations Numbers
  22. Design Lab - Kinetics (DCP, CE sections)

    I'm not sure the exact score I received on this, but I scored a 6 overall on HL Chem. My unmoderated IA scores were projected 5-6s from what I remember.This has only the DCP and CE sections, as we submitted the Design part separately and I have no idea where it is.
  23. chem lab copper and silver HL

    To determine the equilibrium constant and free energy for the redox reaction between iron and copper at different temperatures.
