Why we chose this for our experiment ?

• Probably everyone wondered at least once, why do
  halls dissolve in our mouths. Here we will show
  our step by step process of our experiment and
  show why some things dissolve faster than others?
  
• We will use halls for our experiment.

What is Solubility ?
Solubility - In general, solubility is a
substance that dissolve. In the process of
dissolving, the substance which is being
dissolved is called a solute and the substance in
which the solute is dissolved is called a
solvent. A mixture of solute and solvent is
called a solution. .

Materials

• Water (hot and cold)
• 5 cups of the same size
• a marker to label
• 5 cough drops (halls mentho-lyptus)
• A thermometer to take the waters temperature
• A balance to weight the halls after being in the
  water

Methodology

• First we bought 5 of the same cups and for each
  cup we added hot and cold water and mixed them up
  so that each cup had a different temperature of
  water.
• After that we labeled each cup from 1 to 5 with a
  marker.
• Next we took each cup of water its temperature
  (each cup of water needed to have a different
  temperature so our experiment would collect data)
  
• We next dropped a halls in each cup at the same
  time and left it there for 20 minutes to see how
  much mass would have been lost.
• Now that the 20 minutes are up we take out each
  halls out of their cups and put them to dry so
  the water doesnt make it really sticky.
• Next we weight each of them on a balance and see
  how much mass each of the halls lost.
• And now we collect all our information and we
  graph.

Data Table
Original Temperature (F) Original Mass of the Halls (g) Mass Remaining (g)
92 3.7 0.7
98 3.7 0.2
66 3.8 1.3
100 3.8 0.2
80 3.7 0.8

What couldve been different?

• We couldve tested it a few more times since it
  was a short experiment.
• Be able to use more cups so that there wouldve
  been more data.

Conclusion

• In conclusion the highest temperature was the one
  that made the halls dissolve faster then the one
  that was at room temperature.
• Overall it was an exciting experiment and we
  learn many things.
