Transcript

  • 1. Are you a Smartie?
  • 2. Important Definitions:
    Solution: a mixture that appears to be a single substance, but is composed of particles of two or more substances distributed evenly amongst each other
    Examples: Salt water, Gatorade
    Solute: the substance that is dissolved to form a solution
    Examples: Powdered Drink Mixes, Sugar
    Solvent: the substance in which a solute is dissolved.
    Examples: Water, Acetone (Nail Polish remover)
  • 3. 3 Different Tests
    Disciplined Dissolving
    Place a Smartie on your tongue and close your mouth. Start the timer.
    Allow the Smartie to hit the roof of your mouth (also called the hard palette) but do not move it around your mouth.
    Diligent Dissolving
    Place a Smartie on your tongue and close your mouth. Start the timer.
    Swirl the Smartie all around your mouth, but do not use your teeth to chew it.
    Decisive Dissolving
    Place a Smartie on your tongue and close your mouth. Start the timer.
    Chew the Smartie, but do not swallow the pieces. Instead, allow the small pieces to dissolve in your mouth. Your are attempting dissolve the Smartie as fast as possible.
  • 4. Got a Second?
    Converting times to Seconds
    (# Minutes x 60) + Seconds = Total Seconds
    Calculating an Average
    (Your Total seconds + Partners Total Seconds) / 2= Average Seconds
  • 5. Analysis
    When you are allowing the Smartie to dissolve in your mouth you are creating a solution and a solution has 2 parts: solute and solvent. Which of the substances (Smartie or Saliva) was the solute? Solvent?
    Solute: ______________________________
    Solvent: ______________________________
  • 6. Underline the solute(s) and Circle the solvent
    Kool-Aid – Powder, Water, Sugar
    Lemonade – Sugar, Lemon Juice, Water
    Soda – Water, Sugar, CO2 gas, Caffeine
    Air – Nitrogen (78%), Oxygen (21%), Trace Gases (1%)
    Saline Solution for contacts – Salt, Water
    Milk – Lactose (Sugar), Proteins, Fats, Water, Calcium, Vitamin D
  • 7. Based on your answers to #2 of the Analysis what substance do you think we call the “universal solvent” because it dissolves so many things? _______________________________________
  • 8. What effects how quickly something dissolves?
    You should notice differences in the “Average Time to Dissolve” between each Test. What caused the Smartie to dissolve faster in the late tests?
