Year 9 ICAS Science 5-Question Sample

Question 1 of 5 Predicting and concluding

During a fair-test discussion using the first result from the results record, use the table. Which conclusion is best supported?

Toy car distance

Surface	Distance
Rough mat	20 cm
Smooth board	31 cm

A The rough mat made the toy car travel farther. B The smooth board slowed the toy car less than the rough mat. C The two surfaces had exactly the same effect. D The toy car did not move on either surface.

Question 2 of 5 Reasoning and problem solving

In a seed-tray observation using the second result from the results record, a lamp circuit has two batteries, wires and a bulb, but the bulb is not touching both metal contacts. What will happen?

A The bulb will not light because the path through the bulb is incomplete. B The bulb will light because there are two batteries. C The bulb will glow dimly because one metal contact is touching. D The bulb will flash only when the batteries are new.

Question 3 of 5 Investigating

In a water-temperature log using the third result from the results record, students compare how far toy cars roll on two surfaces. What should they keep the same?

A the same surface and different release points B a different car for each surface C the same finish line but different cars D the same car and the same release point

Question 4 of 5 Interpreting

In a rock-sorting activity using the control result from the results record, a desert animal has large ears with many blood vessels. How could this help it survive?

A The ears mainly store water for later. B The ears trap heat so the animal stays warmer. C The ears can help release heat. D The ears only help the animal hear distant sounds.

Question 5 of 5 Observing and measuring

For a sound-vibration test using the comparison result from the results record, use the table. What happened to the water temperature?

Water temperature

Time	Temperature
Start	102 degrees C
After 10 minutes	96 degrees C

A It increased by 6 degrees C. B It decreased by 6 degrees C. C It stayed exactly the same. D It decreased by 198 degrees C.
