Year 5 ICAS Science 5-Question Sample

Question 1 of 5 Observing and measuring

During a class experiment review using the comparison observation 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	18 cm
Plain-water tray	6 cm	14 cm

A The fertiliser tray grew 4 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

In a group investigation task using the morning observation from the results record, use the investigation plan. Which setup is the fairest test?

Fair-test planning

Investigation question	Factor to change
Does fertiliser amount affect tomato plant height?	amount of fertiliser

A Change the fertiliser, soil and watering schedule B Keep the fertiliser the same and change the pot size C Change the amount of fertiliser and keep the same soil, pot size, water and sunlight. D Grow each plant in a different part of the garden

Question 3 of 5 Natural and processed materials

In a science discussion task using the afternoon observation from the results record, use the observations. Which description best fits rubber?

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

Question 4 of 5 Predicting and concluding

In a lab notebook entry using the checked observation from the results record, use the shadow observations. Which conclusion is best supported?

Shadow observations

Time	Shadow length
9 am	72 cm
12 noon	39 cm
3 pm	74 cm

A The Sun appeared highest at 12 noon because the shadow was shortest then. B The Sun appeared lowest at 12 noon because the shadow was shortest then. C The Sun stayed in exactly the same position all day. D The 12 noon shadow proves the object became taller.

Question 5 of 5 Energy and change

During a measure-and-record activity using the updated observation 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	21
3 cm	14
6 cm	7

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.
