A student believes that the reason an object’s appearance alters when it is submerged in water is because light from the object passes from water to air, and that these substances have different densities. What evidence could be collected that would help to test the validity of this theory?
Add objects of different shapes and sizes to the water.
Replace water with other clear fluids of different densities.
Repeat the procedure with different-shaped containers.
