how fast a solid dissolves in water.
Plan a fair test to test your hypothesis. To conduct a fair
test, only one variable should be changed at a time.

affects how fast a solid dissolves in water:
Variable to be changed:
Variables to keep constant:
Temperature of the water
The type of solid
The amount of solid
The amount of water
The rate of stirring
The surface area of the solid
Carry out the investigation and make careful observations/
measurements. Record the observations/measurements
