LS 1.1.5 Predict by making reasonable assumptions about an event or phenomenon based on observations, prior experiences or data.
LS 1.1.9 Define operationally by describing an interpretation of a task carried out and observed in a situation according to determined aspects.
LS 1.1.10 Control variables by determining the responding and constant variables after the manipulated variable in the investigation have been determined.
LS 1.1.11 Make a hypothesis by making a general statement that can be tested based on the relationship between the variables in the investigation.

4. A group of Year 4 students conducted an investigation to test the strength of magnets.
The paper clips of same size were used.

Magnet Size Number of paper clips attracted to the magnet
P Small 6
Q Medium 12
R Large 18
