WebThis is a great warm up to initiate conversation about the density of freshwater and salt water. I put 1 fresh egg in 2 beakers. I then add freshwater to one and salt water to another. I have the students observe and infer about why one egg floats and the other sinks. This can lead to the density of freshwater vs. salt water.

WebJun 4, 2024 · Density is the key reason and is a simple, scientific explanation for why eggs sink in fresh water but float in salted water. Eggs in Water Have Density and Buoyancy An object will sink if it is denser than a buoyant force — in this case the water — and an object will float if its weight is less than the buoyant force. WebDensity is defined as the mass of a particular substance per unit volume. The relative lightness, or ability of a substance to float or rise on a liquid, is called buoyancy. Buoyancy is also the upward pressure or force exerted by a fluid, which causes an object immersed in the liquid to rise or move upwards. megaworld reit price
