animals; higher; asopthon and
transportation of waters and
mineral salts
i) Types of respiratory system;
body surface respiration, Gill
system; trached system; lungs
ACTIVITIES
(d)
i) Use the specimens and charts
of the digestive system of
housefly, butterfly, cockroach,
tapeworm sheep or dog to
illustrate different types of
feeding mechanism
ii) students should observe
provided specimens noting the
various modification found in the
animals
i)set up an experiment on rate of
diffusion of a colored liquid.
ii)students to observe and
record the time
taken by
the colored
i)instruct students to detach, the
leaves of pawpaw, cassava,
allemande or robber ii)observe
and make inference on the
materials the plants detached
above
i)explain the structure of artery
vein using well drawn diagrams
i) Display the Gills remove from
a dead tilapia for students to
observe the various structures.
ii)students to observe the gill
flakes, gill arch and gill filaments

CYCLING IN
NATURE
9.
i). Definition of nutrient cycling e.g.
carbon cycle, oxygen and water
cycle
ii). Representation and processes
of each of the nutrient cycle listed
above
iii). Importance of nutrient cycle to
plants, animals and man
iv). Carbon-oxygen balance
DECOMPOSITION i). Micro and macro decomposers
IN NATURE
ii). Importance and roles of
decomposers to man
ECOLOGICAL
iii). Concept of minimum and
MANAGEMENT:
maximum of tolerance.
TOLERANCE
iv). Geographic range-graph
illustrating maximum and minimum
range tolerance.
(d)
i). Mouth prepared slides
showing respiratory organs of
the earthworm, tilapia, toad,
grasshopper and rats.
ii). Observe that respiratory
organs of various animals
i). ask students to observe
malpighian tubules in a
dissected cockroach and rat
ii). Students to observe and saw
malpighian tubule and the
excretory system in rat and
record their observations.
Lead students to perform
experiment to show absorption
of carbon dioxide and release of
oxygen during photosynthesis ii)
draw the carbon cycle and water
cycle
i). The teacher shall mount
experiment to show that carbon
dioxide, ammonia are released
during decomposition
ii). Show through experiment
that heat is released during
decomposition
iii). The students should identify
the gases released during
decomposition
iv). To guide the student to
perform experiment showing
limit to tolerance v). The
students shall subject the tilapia
fish to different level of salt
concentration and record the
observation on the opercula
movements
