Year 7 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

In a science notebook task 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	10 cm	24 cm
Plain-water tray	10 cm	16 cm

A The fertiliser tray grew 24 cm more because 24 cm is its final height. B The fertiliser tray grew 8 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

During a fair-test discussion 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 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

At the school science bench using the third trial data 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

For an observe-and-explain check 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	37 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

During a fieldwork check 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	19
3 cm	12
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.
