I. The teacher groups the student
into two, one group to collect living
things and the other group to collect
non-living things for comparison.

OF LIVING
THINGS
I) kingdom Monra:Characteristics & examples
ii) Kingdom protista
Characteristics & example
i) Teacher to grow culture of
bacteria and blue – green algae,
asks student to observe the
cultures, record and make
inferences.

CLASSIFICATION
OF LIVING
THINGS CONT.
i) Kingdom fungi:Characteristics & examples
ii) Kingdom plantae :Characteristics & examples
iii) Kingdom Animalia :Characteristics examples
Note: the kingdoms should be
classified into prokaryotes and
eukaryotes: also in kingdom
plantae the difference between
higher and lower plant should
be emphasized.
i) Teacher guide students to uproot
the farm plant, collect lemon, pistia
(water lettuce), break some
branches of shrubs & bring them
into the laboratory, asks student to
observe all the specimens, record
and make inferences.

and animal cells for student to
observe, draw, label and note their
difference and similarities.

and osmosis using living and nonliving components.
i) The teacher sets up experiment to
show the effects of different
nutrients or spirogyra. Asks students
to observe record and discuss
experiments.
i) Teacher sets experiments to show
respiration in yeast (anaerobic) and
respiration in rat (aerobic)
ii) Teacher draws the krebs cycle on
the chalkboard and asks the
students to draw also.
