what is the first step
State the problem
100
Hypothesis
A possible explanation for a problem
100
If the water is hotter then the ice cube will melt faster
Hypothesis
100
if the water is hotter han the tablet will dissolve quicker

what is the second step
research and gather info
200

What is the third step
Form a hypothesis
300
Variable
a quantity that can have more than a single value
300
My hypothesis was right
conclution
300
The time it took for the tablet to dissolve
the DV
300
Specific heat capacity
J/gc

What is the fourth step
test the hypothesis
400
Dependent variable
the value that changes according to the changes in the other variables
400
Why do some bouncey balls bounce higher then others
State the problem
400
The hotter the water the faster the tablet dissolved. When the water was hotter the tablet fizzed more aggressively and that made it dissolve quicker.
