Since the 2025 BECE question formats will change, let’s take a careful look at these Integrated Science Critical Thinking and Application – Revision Questions for 2025 BECE Candidates.
2025 BECE Integrated Science Critical Thinking and Application Questions
Instructions: Answer all the questions. Show all the workings for calculations where necessary.
You are helping your mother in the kitchen. She needs to pour honey into a jar, but it is flowing very slowly. You remember learning about a property of liquids that affects how easily they flow.
Question:
a) i. Explain the key term related to the above in science to your mother. (b) Based on your explanation, why is the honey flowing slowly compared to water? 4( marks)
Kwame, a young farmer, has noticed a decline in the productivity of his land over the past few years. He is concerned about the health of his soil and wants to take steps to improve it.
Question a. (Distinguish): Kwame has heard the terms “soil depletion” and “soil erosion” being used, but he is unsure of the difference. Explain the difference between soil depletion and soil erosion in the context of Kwame’s farm. (2 marks)
Question b (Apply): Based on your understanding of soil depletion, identify three factors that might be contributing to the decline in productivity of Kwame’s farm. Explain how each factor can lead to soil depletion which is currently affecting his crop yield. (4 marks)
During a science fair, Kwame is demonstrating the fascinating phenomenon of light refraction. He sets up an experiment with a rectangular glass block and a laser pointer. When the laser beam strikes the glass block at an angle, it bends as it passes through the glass and exits on the other side.
Questions: (a) Law of Refraction: Kwame wants to explain the scientific principle behind this observation. State the law of refraction of light. (1 mark)
(b) Applications of Refraction: The law of refraction has various practical applications. Explain two ways in which the phenomenon of refraction is used in our daily lives. (2 marks)
- A student used a thermometer to measure the temperature of a beaker of water. The thermometer reading was 25°C. Explain, using the kinetic theory of matter, why the water feels warm to the touch. (2 marks)
- A metal spoon feels colder than a wooden spoon at the same temperature. Explain this observation using the concept of thermal conductivity. (2 marks)
- You are provided with a mixture of sand and salt. Describe, in detail, how you would separate the mixture into its components using physical separation techniques. (4 marks)
- Explain the difference between a conductor, an insulator, and a semiconductor. Give one example of each. (4 marks)
- A basic 2 learner wants to know how a simple electric circuit looks because he heard the basic 5 teacher mention it to his learners during the launch break. Draw a labeled diagram to show the parts of a simple electric circuit. (2 marks)
- Explain why a fuse blows in an electrical circuit when there is an overload of current. (2 marks)
- Describe the process of photosynthesis, including the role of sunlight, water, and carbon dioxide. (3 marks)
- Describe three practical ways you can help reduce your negative impact on the environment. (3 marks)
- Describe the process of refraction, and explain how it is responsible for the bending of light rays when they pass from one medium to another. (3 marks)
- Explain how the human eye focuses light on the retina. (3 marks)
- Describe the function of the following parts of the digestive system: stomach, small intestine, and large intestine. (3 marks)
- Explain the importance of maintaining a balanced diet for good health. (2 marks)
- A student investigates the rate of evaporation of different liquids. Describe two factors that could affect the rate of evaporation in this investigation. (2 marks)
- Explain the importance of sustainable practices in managing natural resources. Give two examples of sustainable practices you will recommend to the Famiye village. (3 marks)
These questions will test your understanding of the science topics using the 2025 BECE Integrated Science Critical Thinking and Application Questions expected format for questions.
