Year 4 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

During a hands-on science session using the first result from the results record, use the growth data. Which interpretation is best supported?

Seedling growth after 10 days

Tray	Starting height	Final height
Fertiliser tray	7 cm	19 cm
Plain-water tray	7 cm	11 cm

A The fertiliser tray grew 19 cm more because 19 cm is its final height. B Both trays grew the same amount because they started at the same height. C The fertiliser tray grew 8 cm more than the plain-water tray. D The plain-water tray grew more because it used less material.

Question 2 of 5 Investigating

During a practical science lesson using the second result from the results record, use the investigation plan. Which setup is the fairest test?

Fair-test planning

Investigation question	Factor to change
Does wing length affect how long a paper helicopter falls?	wing length

A Change the wing length and keep the same paper type and same drop height. B Change the wing length, paper type and drop height C Keep the wing length the same and change the drop height D Drop each helicopter from a different window

Question 3 of 5 Natural and processed materials

During a fieldwork check using the third result from the results record, 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 transparent insulator. B Glass is best described as a liquid sample. C Glass is best described only by its colour. D Glass cannot be classified from observations.

Question 4 of 5 Predicting and concluding

In a data-recording task using the control result from the results record, use the shadow observations. Which conclusion is best supported?

Shadow observations

Time	Shadow length
9 am	79 cm
12 noon	60 cm
3 pm	40 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 Sun appeared highest at 3 pm because the shadow was shortest then. D The 3 pm shadow proves the object became taller.

Question 5 of 5 Energy and change

For a predict-and-check question using the comparison result from the results record, use the magnet data. Which conclusion is best supported?

Paper clips lifted by a magnet

Distance from clips	Clips lifted
1 cm	22
3 cm	15
6 cm	8

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