B Add water to the sand until it will form a ball. C Use a 3 oz. D Then use a squeeze bottle to slowly add water to the center of the tower. E Continue adding water and observe changes. Write your observations and summarize the results.
Water is held between sand particles and holds the particles together.
Wet sand will hold shape in a right angle. But as more water is added, there is eventually enough water in the sand that the water layers will be too thick to hold the sand particles together and the tower will slump. So a little water holds it together, but a lot of water will make it fall apart. Write your observations and summarize the results. III A Weigh 10 g of dry sand into a small beaker.
