X : Carbon dioxide

Y : Glucose

Producing food /producing oxygen

To absorb carbon dioxide

Plant B

Plant B can do photosynthesis because carbon dioxide is

present.

The indicator colour droplet moves towards the test tube.Volume of air decreases

.oxygen is used for respiration

Put in bigger container/ Remove the container

Contain more oxygen/ more air .

Global warming / green house effect

Situation K: Potential energy

Situation L: Kinetic Energy

Ball bearing

Use ball bearing/ put grease/put roller/

To reduce friction between box and floorWear spiked shoes/ wear rubber soled shoes/wear wollen

glove/put flour on the palm

To increase frictional force between hand and the wall

Metal / Logam Observation/ Pemerhatian

Zinc Powder Metal burns brightly

Copper Powder Metal glows brightly

Copper , zinc , magnesium

Solid calcium hydroxide / slaked lime

Dissolves it in water

Calcium, carbon / oxygen

Turns lime water cloudy/ milky

43 ml

Container C has highest rate of evaporation because it has

largest surface area.

The larger the surface area, the higher the rate of evaporation/

the smaller the surface area, the lower the rate of evaporation

Water able to

evaporates

Water not able to

evaporates

P , S Q , R

x takes the shorter time to dry compare to W

X takes the shorter time to dry because of factor wind

movement

Condition z has lower rate of evaporation because of factor of

humidity of air.

More than 20 minThe larger the surface area, the higher the rate of evaporation
