Please take note of the following:

Pg 2 For Observations question 1 answer, the diagrams for A and B should be

further slied into half !showing onl" half of the #$sha%ed eler" stalk&'

Pg ( For )*tension question 2, the %u%ils are not e*%eted to ut along the dotted

line on the %age'

Concepts

Plants have a trans%ort s"stem'

Plants have a set of tubes that arr" water from the roots to other %arts of the %lants,

also known as the *"lem'

Specific o!ectivesPu%ils should be able to:

state that %lants have water$arr"ing tubes

state that the water$arr"ing tubes in %lants trans%ort water from the roots to other

%arts of the %lants

Observing +o use the senses andor instruments

to notie the surroundings, in order tolearn or understand the harateristis,%ro%erties, similarities, differenes andhanges of ob-ets or events

B" observing the %arts of the

eler" stalk that are stained withfood olouring

.om%aring +o identif" the similarities ordifferenes between ob-ets, ideas,%rini%les or series of ations

B" om%aring the movement ofwater in different %arts of theeler" stalk

.ommuniating +o understand and be able to informothers of information that is %resentedin different forms words, diagrams,

%itures, tables, gra%hs et'

B" drawing the stained ross$setion of the eler" stalk
