Final answer:
Aiden can conclude that the sand settled at the bottom, the clay formed a layer above the sand, and the water remained on top.
Step-by-step explanation:
Aiden can conclude that the sand settled at the bottom, the clay formed a layer above the sand, and the water remained on top. This is because sand and clay do not dissolve in water, so when the bottle was shaken and left undisturbed, gravity caused the sand to settle at the bottom and the clay to form a layer above it. The water, being the least dense, remained on top.
