Year 9 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

During a science-lab rotation using the updated evidence note 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	8 cm	18 cm
Plain-water tray	8 cm	13 cm

A The fertiliser tray grew 5 cm more than the plain-water tray. B The fertiliser tray grew 18 cm more because 18 cm is its final height. 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

At the school science bench using the initial evidence note from the lab notebook, use the investigation plan. Which setup is the fairest test?

Fair-test planning

Investigation question	Factor to change
Does water temperature affect how quickly sugar dissolves?	water temperature

A Change the water amount, sugar mass and temperature B Keep the water temperature the same and change the sugar mass C Change the water temperature and keep the same water amount and same sugar mass. D Use different cups and different stirring times

Question 3 of 5 Natural and processed materials

During a science revision round using the final evidence note from the lab notebook, 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

During a class experiment review using the follow-up evidence note from the lab notebook, use the shadow observations. Which conclusion is best supported?

Shadow observations

Time	Shadow length
9 am	41 cm
12 noon	66 cm
3 pm	67 cm

A The Sun appeared lowest at 9 am because the shadow was shortest then. B The Sun stayed in exactly the same position all day. C The 9 am shadow proves the object became taller. D The Sun appeared highest at 9 am because the shadow was shortest then.

Question 5 of 5 Energy and change

During a practical science lesson using the first fair-test variable 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	18
3 cm	11
6 cm	5

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.
