My Experiment ( typed up )

Aim : To determine whether the temperature of the water affects the solubility of the Panadol tablet.

Hypothesis : If the temperature of the water increases , then the Panadol tablet will dissolve faster.

Dependent Variable : The time it takes for the Panadol tablet to dissolve ( i will measure the time by using stopwatches ) 
Independent Variable : Temperature of the water 
Controlled Variable : Same Panadol tablet , Same amount of water , Same plastic cup

Equipment :Stopwatch , 3 types of water ; normal ( room temperature water ) , Cold ( iced water ) , Hot ( Boiling water ) ,9 Panadol  Rapid Soluble tablets 
( soluble) , 3 clear plastic cups, Measuring cup ( optional ), marker ( to write on the plastic cups )
Sheet of paper ( optional )
Method : 
1. Gather all your equipment 
2. Label your cups ( Normal , Cold and Boiling )
3. Fill the cup labelled 'normal' to half way or label the sheet of paper ' normal '
4. Place one Panadol Rapid Soluble tablet into the cup 
5. Measure the time it takes for the Panadol tablet to dissolve using the stopwatch
6. Record your results
7. Repeat steps 3-6 , this time using the 'Cold' and 'Boiling' cups.
8. Repeat this experiment two more times to ensure reliability & validity
9. Find the averages of the different time it takes for the Panadol tablet to dissolve
10. Compare results
