1. Do the following experiment. For this experiment on solutions, you will need:

• sugar cubes
• regular granular sugar
• three glasses
• a spoon
• water

You will be dissolving the sugar. Make a chart with three columns with the headings “Water Temperature,” “Sugar Size,” and “Stirred/Not stirred.”

a. Fill one glass with cold water, one with warm water, and one with hot water. Measure one teaspoon of regular granular sugar into each glass. Do not stir the liquid. Using your watch, time how long it takes for the sugar to dissolve in each glass. Record your results on the chart.

b. Try the same thing, but this time place one sugar cube in each glass. Do not stir the liquid. Using your watch, time how long it takes for the sugar cube to dissolve in each glass. Record your results on the chart.

c. Now repeat steps a. (regular sugar) and b. (sugar cube), but this time try stirring the glasses of water each time. Using your watch, time how long it takes for the sugar to dissolve in each glass. Record your results on the chart.

2. Based on the results, what conclusions can you draw. Record your conclusions and any observations in the data table.
