To find out the relationship between the time and the
temperature of liquid X.
Increase
If the time taken increase, the temperature of liquid X
increase.
As the time taken increase, the temperature of liquid X
increase.
To find out the relationship between the distance of ball from
light source and the size of the shadow.
Decrease
The longer the distance of ball from light source, the smaller
the size of shadow.
If the distances of ball from the light source increases, the
sizes of shadow decrease.
To study the relationship between the size of moon and the
weight of squid caught.
Increase
The bigger the size of moon, the more weight of squid caught.
If the sizes of moon increase, the weight of squid caught
increase.
To investigate the relationship between the amount of water
sprinkled and the sizes of black patches.
Increase
The more amount of water sprinkle, the bigger the size of
