Year 4 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

During a hands-on science session using the first trial data from the lab notebook, use the growth data. Which interpretation is best supported?

Seedling growth after 10 days

Tray	Starting height	Final height
Fertiliser tray	7 cm	16 cm
Plain-water tray	7 cm	15 cm

A The fertiliser tray grew 16 cm more because 16 cm is its final height. B The fertiliser tray grew 1 cm more than the plain-water tray. C Both trays grew the same amount because they started at the same height. D The plain-water tray grew more because it used less material.

Question 2 of 5 Investigating

For an observe-and-explain check using the second trial data from the lab notebook, use the investigation plan. Which setup is the fairest test?

Fair-test planning

Investigation question	Factor to change
Does ramp height affect the distance a trolley rolls?	ramp height

A Change the trolley, ramp height and floor surface B Keep the ramp height the same and change only the trolley C Change the floor surface and keep every ramp height the same D Change the ramp height and keep the same trolley and same floor surface.

Question 3 of 5 Natural and processed materials

During a class experiment review using the third trial data from the lab notebook, use the observations. Which description best fits copper?

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 Copper is best described as a liquid sample. B Copper is best described only by its colour. C Copper is best described as a metal conductor. D Copper cannot be classified from observations.

Question 4 of 5 Predicting and concluding

During a fair-test discussion using the control trial data from the lab notebook, use the shadow observations. Which conclusion is best supported?

Shadow observations

Time	Shadow length
9 am	78 cm
12 noon	79 cm
3 pm	34 cm

A The Sun appeared lowest at 3 pm because the shadow was shortest then. B The Sun stayed in exactly the same position all day. C The 3 pm shadow proves the object became taller. D The Sun appeared highest at 3 pm because the shadow was shortest then.

Question 5 of 5 Energy and change

In a science skills warm-up using the comparison trial data from the lab notebook, use the magnet data. Which conclusion is best supported?

Paper clips lifted by a magnet

Distance from clips	Clips lifted
1 cm	21
3 cm	14
6 cm	6

A The magnetic effect was stronger when the magnet was farther from the clips. B The magnetic effect was weaker 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.
