UNIT 8 PUSH AND PULL
(1) We push and pull to do many things. Example, play basketball, weeding, push trolley, play kites, sawing, scrubbing floor.
(2) Pushing and pulling can
(a) change the shape of objects.
(b) make things speed up.
(c) make things slow down.
(d) make things change direction.
(3) How things move depends on their sizes and how hard we push or pull them.
(a) The harder we push and pull, the further the things moves.
(b) If we push or pull equally hard, the smaller thing will move further.
(c) We should do the tests fairly.

UNIT 7 MIXING THINGS
(1) Some materials can dissolve in water. They will disappear in water. Example: sugar, salt, instant coffee powder and milk.
(2) When a material dissolves in water, we get a solution.
(3) Some materilas cannot dissolve in water. These materials do not dissapear in water. Example: sand, coin, key and leaf.
(4) You can check whether something dissolves in water by
(a) tasting the mixture
(b) filtering the mixture
