• 1 sugar cube
• water (500ml)
• granulated sugar in a sealed container
• 2 bottles with caps, labeled A and B
• waste cup
• safety goggles
• teaspoon
• super fine sugar sample
• graduated cylinder

Directions:

1. Put on safety goggles. Do not taste any substance in this activity. Clean up any spills immediately.
   
   
2. Use your hand lens to carefully observe the sugar cube and the super fine sugar. Which form of sugar has the smaller size particles? _______________________
   
   
3. Add 50 ml of water to the two (2) bottles).
   
   
4. Drop one sugar cube into bottle A and close the bottle tightly.
   
   
5. Count how many shakes it takes to totally dissolve the sugar cube.
   
   
6. Record your data in the data table below.
   
   
7. Place one level teaspoon of super fine sugar into Bottle B and repeat steps 5 and 6.
   
   
8. Dump the contents of the two (2) bottles into the waste cup and rinse the bottles. Leave one bottle on the desk and let it stand without movement.

   Number of Shakes

    

9. Draw a line graph showing the number of shakes needed to dissolve the two forms of sugar. Use the grid below. Make sure you include the appropriate range and interval of numbers on the y-axis.

   

10. Use your hand lens to carefully observe the particle size of the granulated table sugar. Use the information from the line graph. Predict the number of shakes it would take to completely dissolve one level teaspoon of the granulated table sugar in the same amount of water.

    ________________________________

11. Write a generalized statement which explains the relationship between the particle size of the sugar and the number of shakes needed to dissolve the sugar.
