DATE

WATER

7 UP

APPLE JUICE

Feb. 4, 2006

• crystals started to grow on the bamboo skewer

• sugar has settled to the bottom of the jar

• liquid is clear

 

• crystals started to grow on the bamboo skewer

• sugar has settled to the bottom of the jar

• liquid is clear

• more crystals were observed on bamboo skewer in the apple juice

• sugar has settled to the bottom of the jar

• liquid is clear

Feb. 5, 2006

• crystals growing

• the water level was lower than the apple juice and 7-Up jar (water might have evaporated in the water jar)

• thick in places and thin layers of sugar forming at the top of this liquid

 

 

• really thin layer of sugar forming on top of this liquid

• thin sugar forming on the top of this liquid

Feb. 10, 2006

• really thick sugar forming on top of the liquid

 

 

• thin sugar forming on top of the liquid

• thick sugar forming on top of the liquid

Feb. 14, 2006

• thick layers of sugar forming on top of the liquid

• crystals getting bigger on the bamboo skewer

 

 

• thin layers of sugar forming on top of the liquid

• crystals getting bigger on the bamboo skewer

• thick layer of sugar forming on top

• crystals are getting bigger on the bamboo skewer

Feb. 16, 2006

• thick layer of sugar forming on top

• crystals are growing bigger on the bamboo skewer

 

 

• thick layer of sugar forming on top

• crystals are growing bigger on the bamboo skewer

• thick layer of sugar forming on top

• crystals are growing bigger on the bamboo skewer

• mass of sugar crystals and bamboo skewer 4.425 g

• 4.425 -1.334 = 3.091 g

 

• mass of sugar crystals and bamboo skewer 4.655 g

• 4.655 - 1.334 = 3.321 g

• mass of sugar crystals and bamboo skewer 4.970 g

• 4.970 - 1.334 = 3.636 g

February 17, 2006
  • to find the average mass of a bamboo skewer, mass 5 bamboo skewers on an electronic balance.
  • take the total number 6.670 g ÷ 5 = 1.334 g
  • massed the individual sugar crystals and bamboo skewers
  • the saran wrap stuck to the sugar crystals, so it was trimmed to be minimal. It should not have an effect on the mass of the sugar crystals.
  • did this aspect under the supervision of Jill Howarth, science teacher at Collingwood Collegiate Institute. Discussed project with her. J. Howarth (personal communication. February 17, 2006)
