Floating egg eggs sinkMaterials and equipment1. salt.2 fresh eggs.3. size 500 cm3 beaker4. water supply5. spoon, scoop the substance.6. glass rods people substances.Experimental methods.1. pour tap water put into the beaker beaker about half. Bring the fresh egg put into water (gently). And observe the results, and then bring the eggs out.2. put salt into original beaker using glass rods, spoon about 5 people until the salt melted. Bring the egg leaves the original notice and enter the result.The trial results.When the eggs will find that fresh tap water put into plain. The weight of the eggs will sink down into the egg, pull the butt beaker because the density of eggs is greater than the density of water. Water buoyancy and therefore cannot give rise to eggs, but when put into the salt water of fresh egg spoon original leaves are floating from the butt beaker approximately 8 cm high 10 cm from the water level because the brine concentration rather than, or in other words, there is more than plain tap water density. Egg has a density less than salt water, so it can float.If the trial results and knowledge from this trial used in everyday life. We could say that measles, swimming in the sea is likely to be severely malnourished than swimming in the River, because sea water has a density greater than water in the river.
