TRANSPORT SYSTEM
Discuss the need for transport systems within
living organisms.
Explain how Transport in plants (transpiration
and root pressure) takes place. Include
necessity, surface area/volume ratio; transport
in plants, transpiration, and movement of
nutrients.
Define transpiration in plants.
Define translocation.
Relate the structures of the xylem and phloem
vessels to their structures.
CIRCULATORY SYSTEM
Discuss the composition of blood and types of
blood cells and their functions. Structures of
the heart; heart beat; names of major blood
vessels and organs associated with the
circulatory system.
Relate the structure of the circulatory system
in human beings to their functions.
Explain the importance of a double circulatory
system in mammals.
Identify the blood groups; A, B, AB and O:
antigen and antibody for each group,
precaution in transfusion and handling; Rh
factor- risk in pregnancy and precautions.

TEXT(S):
TERM: First Term
Weeks 5-8
SENSE ORGANS AND COORDINATION
Describe the structure and function of the
nervous system. (How stimulus is associated
with sense organs).
Discuss the functions of the Brain, sensory and
motor neurons (receptors, control and
effectors). Voluntary and involuntary actions
(students must understand that nerves carry
messages using chemical and electrical
energy).
Describe the function of the endocrine system.
Include
the hormones produced: thyroid,
pancreas, sex organism, adrenal glands and
pituitary glands.
Explain how feedback control and how life
processes are regulated by such. Feedback
control: detection of deviation, set range of
values.
Discuss how Endothermic and ectothermic
animals (advantage of being endothermic).
MAMMALIAN EYE
1. Relate the structures of the mammalian eye to
their functions.
2. Discuss accommodation and the control of the
amount of light entering the eye.
Weeks 9-15
TEMPERATURE CONTROL AND
VENTILATION
1. Describe the methods of heat transfer and their
applications.
2. Define the terms Conduction, convection,
radiation and give examples of each.
3. Distinguish the difference between (land and
sea breezes) and how they are beneficial.
4. Define the term temperature and its units of
measurement.
5. Describe the types of thermometers in relation
to the principles by which they work.
6. Explain the principle by which
thermostatically controlled household
appliances operate. (Electrical and gas ovens,
electrical irons).
7. Discuss the importance of a bimetallic strip
and the different metals used in making them.
8. Define the term evaporation and describe the
cooling effects of evaporation.
9. Discuss the importance of Sweating and
metabolic rate.
10. Define the term ventilation.
11. Discuss the need for proper ventilation and the
effects of poor ventilation on the body.
5. Explain possible causes of cardiovascular
diseases; (a) Hypertension; (b) Heart attack;
(c) Stroke.
6. Explain how the principles of immunization
are used in the control of communicable
diseases
3. Distinguish between natural and artificial
12. Distinguish the difference between natural and
lighting;
artificial ventilation. State examples of each.
4. Distinguish among transparent, translucent and
(features of buildings (raised roofs))
opaque materials;
5. Describe how to separate white light into its
component colors; (Glass or water prisms can
be used.)
6. Explain sight defects and their corrections;
including long and short-sightedness; effects
of bright light and physical injury;
7. Function of convex and concave lenses.
8. Effects of bright light.
9. Correction using convex and concave lenses.
THE MAMMALIAN EAR
1. Relate the structures of the mammalian ear to
their functions.
2. Discuss the approximate audio frequency
spectrum of the human ear; and the effects of
loudness and pitch on human beings.
3. Distinguish the difference between loudness
and pitch and its effects on human beings.
