Experiment "Floating Egg"

The experiment "Floating Egg" involves observing the behavior of an egg in different solutions. The materials required for this experiment are three transparent containers, a raw egg, a spoon, and salt.

1. Step 1: - Place a raw egg in one of the containers and fill it with water from the tap. - Observe what happens to the egg. Take note of your observations in a notebook.

When the egg is placed in water, it sinks to the bottom. This is because the density of the egg is greater than that of water. The egg sinks due to gravity [[1]].

2. Step 2: - Pour a saturated salt solution into the second container. - Place the raw egg into the salt solution. - Observe what happens to the egg. Record your observations in the notebook.

When the egg is placed in the salt solution, it floats to the surface. This happens because the saltwater solution is denser than the egg. The increased density of the saltwater creates buoyant force that is greater than the weight of the egg, causing it to float [[2]].

3. Step 3: - Submerge the egg in the third container. - Pour water alternately from one container to another. - Observe what happens to the egg. Record your observations in the notebook.

When the egg is submerged in the third container and water is poured alternately from one container to another, the egg remains suspended in the middle. This is due to the balance of forces acting on the egg. The forces of gravity and buoyancy are equal, resulting in the egg staying in the middle of the container [[3]].

In this experiment, the object of investigation is the raw egg, while the subject of investigation is the behavior of the egg in different solutions. The experiment aims to understand the effects of density and buoyancy on the egg's behavior in water and saltwater solutions [[1]] [[2]] [[3]].
