Aims/Objectives

Candidates were expected to:

1. Set up simple experiments correctly.

2. Follow a sequence of instructions accurately.

3. Collect and analyze experimental data precisely.

4. Make deductions from results.

5. Plot and interpret graphs correctly.

6. Demonstrate understanding of underlying theories.

Performance was consistent with previous years, with a mean score of 26 and standard deviation of 9.00, compared to 25 and 10.25 in earlier exams.

Common Weaknesses

Some areas candidates struggled with include:

• Recording measurements to correct decimal places and significant figures.

• Plotting points accurately on graphs.

• Choosing appropriate scales and axes labeling.

• Making deductions from graph analysis.

• Stating precautions clearly in scientific language.

• Managing time efficiently.

• Recording observations in the prescribed format (aim, apparatus, method not written).

• Expressing ideas clearly in English.

Suggested Remedies

1. Employ qualified physics teachers to train candidates.

2. Conduct workshops on laboratory activities.

3. Provide sufficient practical equipment in schools.

4. Train and retrain physics teachers.

5. Expose candidates early to practical physics exercises.

6. Organize practice exercises for data collection and graph plotting.

7. Collaborate with Mathematics teachers for mastering graphs and slopes.

Candidate Strengths

• Proper presentation of tables with correct units.

• Accurate graph plotting and slope evaluation.

• Correctly answering structured response questions linked to practical experiments.

Sample WAEC GCE Physics Questions and Answers 2025

Question 1: Apparatus Identification

Q: Identify the apparatus used for the following tasks:

• Holding hot test tubes, beakers, or crucibles – Tongs.

• Supporting glassware over a flame – Wire gauze.

• Supporting a gas jar during gas collection – Beehive shelf.

• Transferring small amounts of solid chemicals – Spatula.

A:

• Tongs: Hold hot containers, pick small items, remove hot lids, place objects in flames.

• Wire Gauze: Distribute heat evenly, support beakers, prevent glass breakage.

• Beehive Shelf: Stabilize gas jars and direct gas from delivery tubes.

• Spatula: Transfer, mix, scoop, or scrape solid chemicals.

Question 2: Separation Techniques

Q: Name the methods used to separate liquids with different boiling points.

A:

• Distillation: Separate liquids with widely different boiling points.

• Fractional Distillation: Separate miscible liquids with closer boiling points.

Question 3: Gas, Solid, and Liquid Reactions

Q: Complete the reactions:

• Hydrogen (H₂) reacts with magnesium (Mg) and dilute HCl.

• Carbon dioxide (CO₂) reacts with calcium carbonate (CaCO₃) and dilute HCl.

• Acetylene (C₂H₂) reacts with calcium carbide (CaC₃) and cold water.

Question 4: Reaction with Dilute Hydrochloric Acid

Q: Predict outcomes when HCl is added to sodium hydroxide and sodium carbonate.

A:

• NaOH(aq): No visible reaction; forms water and salt.

• Na₂CO₃(aq): Effervescence occurs due to CO₂ gas. Bubble through limewater to confirm milkiness.

Question 5: Graph Plotting

Q: What precautions should candidates observe while plotting graphs?

A:

• Correctly label X and Y axes.

• Choose suitable scales.

• Plot points accurately.

• Deduce trends and slopes correctly.

• Present graphs neatly with units included.

Question 6: Practical Tips

1. Practice practical experiments regularly.

2. Record observations in the correct format.

3. Work under guidance of qualified physics teachers.

4. Master graph plotting and slope evaluation.

5. Manage time efficiently during exams.

Conclusion

The 2025 WAEC GCE Physics Practical for Nov/Dec Private Candidates highlights areas where candidates excelled and areas needing improvement. With proper practice, guidance, and exposure to practical exercises, candidates can improve significantly in future GCE Physics practical exams.
