Results conducted from my second experiment !


These are the results that I gathered from my second experiment :

Normal Water : It took 1 minute and 42 seconds for the tablet to dissolve

Cold Water : It took 2 minutes and 6 seconds for the tablet to dissolve

Hot Water : It took 40 seconds for the tablet to dissolve

So after completing my second experiment to test if the temperature of the water affects the rate that the Panadol tablet dissolves , i was convinced that the Panadol tablet would always dissolve the fastest in hot water. Although i am very sure that my hypothesis is correct i still would like to conduct a third experiment in order to support my entire experiment  and also to ensure reliability & validity. These two factors are extremely important hence that is why i  make sure all my measurements add up !
Keep a look out for my the results of my third experiment , it should be posted up very soon ! :D

Table of my results :


 Condition of Water
Reaction time (S) 
Trial 3
Normal Water ( Room temperature water )
102 seconds to dissolve
Cold Water ( Iced Water )
126 seconds to dissolve
Hot Water ( Boiling Water )
40 seconds to dissolve

Results conducted from my first experiment !

The results collected from this experiment were as follows :

Normal Water : It took 1 minute and 40 seconds for the tablet to dissolve

Cold Water : It took 2 minutes for the tablet to dissolve

Hot/Boiling Water : It took 42 seconds for the tablet to dissolve


From this experiment it was clearly evident that the Panadol tablet dissolved the fastest in the hot water.
After viewing my results i came to accept my hypothesis as i predicted that the Panadol tablet would dissolve the fastest in the hot water , and so it did. However , i cannot base my whole experiment on these results therefore i must repeat this experiment two more times in order to ensure my results are reliable. I kind of had an assumption as to what the results of the next repeated experiment would be , i was sure that the hot water would still be the fastest in dissolving the water , followed by cold water and finally normal water would be the slowest to dissolve the Panadol tablet.
I guess i'll just have to wait and see until i complete my next experiment!
stay tuned  :)


Table of my results :




 Condition of Water
Reaction time (S) 
Trial 1
Normal Water ( Room temperature water )
100 seconds to dissolve
Cold Water ( Iced Water )
120 seconds to dissolve
Hot Water ( Boiling Water )
42 seconds to dissolve
 

Although i have previously stated that i would be using a line graph , i have changed my mind as i find that a column graph would be easier for this section.

Week 4 : Conducting my experiment

I have successfully been able to complete my experiment method and i am now able to get the show on the road ! :D

i have recorded myself conducting Trial 1   of my experiment enjoy !

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

Mind Map of my experiment

After much thought and consideration i finally decided to do a mindmap of my experiment 
which outlines exactly what i am going to be doing over the next few days or so ! :D



Technique for collecting data

Since my experiment will be involving many different numbers i will need to put my results into a table and graph so that i can clearly analyse my results without being confused.
By placing my results into a table and a graph it will be easier for me to identify the factors that need to be taken into consideration , such as the rate it takes the tablet to dissolve in hotter water rather than cooler water. This is very important for me to visualise as i will need to discuss and conclude my results.

I have designed my table where i will later on place my results into to :




Condition
Reaction TIme 
-------------------------------------
Trial 1 | Trial 2 | Trial 3
Average Reaction Time ( s)
Normal Water ( Room Temperature water )


Cold water ( iced water )


Hot Water ( Boiled water )




My next step was to set out my graph , now this was tricky. I had to decide on whether i was going to do a column graph , bar graph or a line graph.
I came to the conclusion to do a line graph as i knew my data could be easily read on this graph .
