Question 1 · 1 mark · Difficulty 2/3

A student investigating the effect of temperature on the rate of fermentation in cane juice planned to use five different temperatures. Which of the following is the MOST suitable range of temperatures to use in this investigation?

  1. 10°C, 20°C, 30°C, 40°C, 50°C
  2. 15°C, 16°C, 17°C, 18°C, 19°C
  3. 0°C, 25°C, 50°C, 75°C, 100°C
  4. 30°C, 35°C, 70°C, 75°C, 80°C
Show answer & explanation
✓ Answer: A — 10°C, 20°C, 30°C, 40°C, 50°C
Award 1 mark for selecting 10°C, 20°C, 30°C, 40°C, 50°C. This range provides regular 10°C intervals covering the typical range for enzyme activity and fermentation. B is incorrect because the temperature range is too narrow (only 4°C difference) to show significant changes in fermentation rate. C is incorrect because 0°C and 100°C are extreme temperatures that would stop fermentation entirely, providing no useful comparative data. D is incorrect because the intervals are irregular and the range focuses only on high temperatures where enzymes would denature.
Question 2 · 1 mark · Difficulty 2/3

Students in Barbados investigated the effect of different concentrations of fertilizer on the growth of okra plants. They measured plant height after 4 weeks. Which of the following would be the BEST way to present their results?

  1. A pie chart showing the proportion of each fertilizer concentration used
  2. A bar chart with fertilizer concentration on the x-axis and mean plant height on the y-axis
  3. A line graph with time on the x-axis and plant height on the y-axis
  4. A table only, with no graphical representation
Show answer & explanation
✓ Answer: B — A bar chart with fertilizer concentration on the x-axis and mean plant height on the y-axis
Award 1 mark for selecting a bar chart with fertilizer concentration on the x-axis and mean plant height on the y-axis. Bar charts are appropriate when the independent variable (fertilizer concentration) is categoric or discrete. A is incorrect because pie charts show proportions of a whole, not the relationship between two variables. C is incorrect because line graphs are used when both variables are continuous and typically when showing change over time throughout the investigation. D is incorrect because graphical representation makes patterns and trends easier to identify and is expected in good experimental reporting.

CXC CSEC Chemistry: Planning and Evaluating Experiments FAQ

How many CXC CSEC Chemistry questions on Planning and Evaluating Experiments are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Planning and Evaluating Experiments for CXC CSEC Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Planning and Evaluating Experiments practice with other Chemistry topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Planning and Evaluating Experiments questions aligned to the official CXC CSEC Chemistry syllabus?
Every question is written against the published CXC CSEC Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Planning and Evaluating Experiments typically tested on CXC CSEC Chemistry papers?
Planning and Evaluating Experiments appears across multiple question types on real CXC CSEC Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
