Are You A Smartie

  1. 1. Are you a Smartie?<br />
  2. 2. Important Definitions: <br />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<br />Examples: Salt water, Gatorade<br />Solute: the substance that is dissolved to form a solution<br />Examples: Powdered Drink Mixes, Sugar<br />Solvent: the substance in which a solute is dissolved. <br />Examples: Water, Acetone (Nail Polish remover)<br />
  3. 3. 3 Different Tests<br />Disciplined Dissolving<br />Place a Smartie on your tongue and close your mouth. Start the timer.<br />Allow the Smartie to hit the roof of your mouth (also called the hard palette) but do not move it around your mouth. <br />Diligent Dissolving<br />Place a Smartie on your tongue and close your mouth. Start the timer.<br />Swirl the Smartie all around your mouth, but do not use your teeth to chew it.<br />Decisive Dissolving<br />Place a Smartie on your tongue and close your mouth. Start the timer.<br />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.<br />
  4. 4. Got a Second?<br />Converting times to Seconds<br />(# Minutes x 60) + Seconds = Total Seconds<br />Calculating an Average<br />(Your Total seconds + Partners Total Seconds) / 2= Average Seconds<br />
  5. 5. Analysis<br />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?<br />Solute: ______________________________<br />Solvent: ______________________________<br />
  6. 6. Underline the solute(s) and Circle the solvent <br />Kool-Aid – Powder, Water, Sugar<br />Lemonade – Sugar, Lemon Juice, Water<br />Soda – Water, Sugar, CO2 gas, Caffeine<br />Air – Nitrogen (78%), Oxygen (21%), Trace Gases (1%)<br />Saline Solution for contacts – Salt, Water<br />Milk – Lactose (Sugar), Proteins, Fats, Water, Calcium, Vitamin D<br />
  7. 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? _______________________________________<br />
  8. 8. What effects how quickly something dissolves?<br />You should notice differences in the “Average Time to Dissolve” between each Test. What caused the Smartie to dissolve faster in the late tests? <br />
