- sugar cubes
- dropper
- beaker of colored water
- waterproof tray
Procedure:
1. Stack the sugar cubes on the tray as shown in the diagram.
2. Put a few drops of colored water on top of one of the cubes.
3. Observe where the water moves through the cubes and how the cubes change.
4. Add water at a crack between two cubes a drop at a time.
5. Observe where the water moves through the cube and how the shapes of the cubes change.
6. Repeat steps 2-5 until you make a hole clear through or the sugar cubes collapse.
During science class, Jose and Richie set up the experiment you see above. Sugar cubes were used for rocks. Colored water in a dropper was used to model rain water. As the boys dropped water on the sugar cubes, they dissolved. What were the boys trying to model?
