Practicals type questions.
2017 BECE Past Examination Practicals l
1a. The diagram below is an illustration of a longitudinal section of a canine tooth in humans.
Study the diagram carefully and answer the questions that follow
I) Name each of the parts labeled I, II, III, IV and V.
II) What is the function of each of the parts labeled I and III?
III) Which of the labeled parts could be affected by tooth decay?
IV) State three ways by which tooth decay maybe prevented
Solution to question 1a.
I) Names of the parts
I- enamel
II- dentine
III- cement
IV- root.
V- pulp cavity
II) functions of the parts
I- tearing flesh
– protecting the dentine Against harm.
III- protects the pulp cavity.
III) part affected by tooth decay.
Pulp cavity
IV) prevention of tooth decay
– avoid eating too much sugary foods.
– avoid eating too cold food.
Avoid eating too hot food
– avoid smoking
– visit the dentist occasionally
Question 1b)
Study the diagram below carefully and answer the questions that follow
I) What phenomenon does the diagram illustrate?
II). Identify each of the parts labeled I, II, III, IV and V.
III). Explain why an object at the bottom of a pond appears closer to the surface than it actually is.
Solution to question 1b.
I) . Identification of phenomenon
Refraction of light
II). Identification of parts.
I- normal
II- incident ray.
III- angle of incidence
IV- angle of refraction
V- refracted ray
III). Explanation to why object in a pond appears closer than normal
Light rays from the object in the pond bend away from the normal as they fall on retina of the observer. Similarly, light rays from air (land) falling on the object in the pond bend towards the normal. This is so because, when light ray moves from a denser medium (water) to a less dense medium ( air), it bends away from the normal and when light ray moves from a less dense medium to a denser medium, it bends towards the normal.

Questions 1c.
In an experiment to separate the components of muddy water, the below setup was used.
Study the diagram carefully and answer the questions that follow.
I). Name each of the parts labeled I, II and III.
II). State the function of the part labeled II.
III). Name the substance obtained asn the filtrate
IV). State three physical properties of the filtrate.
V). Name two other materials that could be used to replace the part labeled II.
Solution to question 1c.
I) Names of parts
I- retort stand and clamp.
II- filter paper
III- funnel
II). Function of the filter paper
– to prevent the residue from entering the beaker with the filtrate.
III). Name of filtrate
– water
IV) physical properties of the filtrate
– it boils at 100°C
– it freezes at 0°C
– it is a universal solvent
-it has no fixed shape, it takes the shape of its container.
Students and teachers should note this carefully;
Points like;
Odourless, colourless and tasteless as stated in most text books are considered as wrong in the marking scheme. This is so because, muddy water can not be odourless, colourless and tasteless just through filtration. Only pure water that is odourless, colourless and tasteless. Muddy water that has been filtered is not a pure water.
V) materials in place of filter paper
– cloth.
– cotton wool
– foam
– gauze

III). Mention four farming practices that could be used to control the process mentioned in (I) above.
IV) . Mention Three soil resources that would be depleted from the farmland when it rains heavily
Solution to question 1d
I). Process likely to occur
– soil erosion (sheet erosion)
II). Farming practices that could cause the process
– bush burning
– continuous cropping
– excessive use of inorganic fertilizer
– overgrazing sand winning
III). Farm practices that could halt the process
– crop rotation
– organic farming
– contour ploughing
– cover cropping
