Year 8 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

During a classroom investigation, use the growth data. Which interpretation is best supported?

Seedling growth after 10 days

Tray	Starting height	Final height
Fertiliser tray	9 cm	18 cm
Plain-water tray	9 cm	14 cm

A The fertiliser tray grew 18 cm more because 18 cm is its final height. B Both trays grew the same amount because they started at the same height. C The fertiliser tray grew 4 cm more than the plain-water tray. D The plain-water tray grew more because it used less material.

Question 2 of 5 Investigating

In a science notebook task, use the investigation plan. Which setup is the fairest test?

Fair-test planning

Investigation question	Factor to change
Does light level affect seedling growth?	light level

A Change seed type, water amount and light level B Change the light level and keep the same seed type, water amount and soil. C Keep light level the same and change the amount of water D Use different soil in every pot

Question 3 of 5 Natural and processed materials

For a fair-test discussion, use the observations. Which description best fits glass?

Material test observations

Material	Observation
copper	conducted electricity and heat strongly
plastic	did not conduct electricity and softened near heat
glass	let light pass through but did not conduct electricity
rubber	stretched and did not conduct electricity

A Glass is best described as a liquid sample. B Glass is best described only by its colour. C Glass is best described as a transparent insulator. D Glass cannot be classified from observations.

Question 4 of 5 Predicting and concluding

During an observation check, use the shadow observations. Which conclusion is best supported?

Shadow observations

Time	Shadow length
9 am	71 cm
12 noon	36 cm
3 pm	73 cm

A The Sun appeared lowest at 12 noon because the shadow was shortest then. B The Sun stayed in exactly the same position all day. C The Sun appeared highest at 12 noon because the shadow was shortest then. D The 12 noon shadow proves the object became taller.

Question 5 of 5 Energy and change

In a practical science question, use the magnet data. Which conclusion is best supported?

Paper clips lifted by a magnet

Distance from clips	Clips lifted
1 cm	18
3 cm	11
6 cm	8

A The magnetic effect was weaker when the magnet was farther from the clips. B The magnetic effect was stronger when the magnet was farther from the clips. C Distance had no effect because the same magnet was used. D The magnet stopped being magnetic after the first trial.
