Scientific MethodQuestion you should ask yourself
Discussion and conclusionWhat really did happen?
Why did this happen?
Did I find out what I wanted to know?
(What change did you notice in the appearance of the sugar cubes? Were these changes due to chemical or physical weathering? What reason(s) did you give for these changes? What is the evidence? How did the continued shaking change the cubes appearance? Describe where this occurs in nature.______

Part B: The effect of surface area and temperature on Weathering
Procedure B-1
1. Place two sugar cubes on a paper towel.
2. Carefully crush one, try not to lose any of the mass.
3. Place one sugar cube in one beaker of water and the crushed sugar cube in the second beaker of
water.
Full Sugar Cube
Crushed Cube
4. Observe the rate of time it takes for each mass of sugar to dissolve and record as either fast or slow.
Procedure B-2
- Fill one beaker up with cold water and one with hot water.
- Place a sugar cube in each of the beakers
- Observe the rate of time it takes for each mass of sugar to dissolve and record as either fast or slow.
Form / Time to Dissolve
Cube in Cold Water
Cube in Hot water
Questions
1. For Procedure B-1, which form of sugar dissolved more quickly? Why?
2. For Procedure B-2, which sugar cube dissolved more quickly, the one in the cold water or the one in
the hot water? Why?
3. For the hot vs. cold sugar cubes, were these changes due to chemical or physical weathering?
Conclusion
What is the difference between physical and chemical weathering?
What factors affect the rates of physical and chemical weathering? (Use your notes)
Where do you see physical and chemical weathering on a daily basis?
