5. Clay

2. Gravel or perhaps pebbles

* 3 20 mL coloured liquid

* timer


Time interest: 40 a few minutes

1 . Label the cylinders as A, N and C.

Put fine sand in cyndrical tube A, gravel/ pebbles in cylinder N, and clay in canister C. 4. When the termes conseilles is prepared, pour the first glass of shaded liquid in to cylinder A. Start timing as soon as the water is put into the canister. 5. Observe how the the liquid flows throughout the sand.

6. End timing as soon as the liquid extends to the bottom from the cylinder. The liquid will not be equally allocated in the fine sand. As soon as one part of the bottom level gets damp, stop the timer. six. If the liquid has not come to the bottom in 15 minutes, prevent timing.
