this is what i have decided to do my experiment on.
I will do this experiment by adding substances (pepper, salt, sugar, sand, nothing added) to ice cubes and determine which one melts the fastest. This experiment will be repeated 3 times for each substance.
independent variables:
the substances i.e. salt, pepper, sugar, sand, compared to when nothing is added
dependent variables:
percentage of the ice cube remaining
percentage of the ice cube that melted
controlled variables:
same size ice cube (volume)
same water, tap
time in which the ice melts (10 minutes)
same place for each experiment
same amount of the substance added (1 teaspoon)
use same scales to measure
