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

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

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
