Year 9 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

In a lab notebook entry 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	6 cm	19 cm
Plain-water tray	6 cm	10 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 9 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 skills warm-up 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 salt amount affect the boiling time of water?	amount of salt

A Change the salt amount, water volume and heat setting B Keep the salt amount the same and change the pot size C Use a different stove for every trial D Change the amount of salt and keep the same water volume and same heat setting.

Question 3 of 5 Natural and processed materials

During a science revision round using the third result from the results record, use the observations. Which description best fits plastic?

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

Question 4 of 5 Predicting and concluding

In a science inquiry 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	37 cm
3 pm	61 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 12 noon shadow proves the object became taller. D The Sun appeared highest at 12 noon because the shadow was shortest then.

Question 5 of 5 Energy and change

For an observe-and-explain check 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	5

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.
