How Much Salt To Make An Egg Float Science Fair Project

Consider what the results tell you about pollution in the ocean for example. A serial dilution is a method for accurately diluting a solution in regular steps.

Density is a measure of the mass per unit volume of a substance.

How much salt to make an egg float science fair project. How does the floating egg science experiment work. You could narrow down the range further by testing additional saltwater solutions. In this science fair project you will figure that out by using the technique of making serial dilutions.

Our science fair project is on whether an egg can float in salt water or not. Step 5 place the egg into the glass and watch it float. Salt water is denser than ordinary tap water the denser the liquid the easier it is for an object to float in it.

So it turns out an egg can float in salt water but you need a certain amount salt for a egg to float in salt water. Can an egg float on salt water physics projects model experiments for cbse icse isc stream students and for kids in middle school elementary school for class 5th grade 6th 7th 8th 9th 10th 11th 12th grade and high school msc and college students. The answer lies in the density of water.

The buoyant force the force making the egg float is equal to the weight of the fluid the object displaces. Simply said how much stuff in a given volume. But just how much salt is needed to make an egg float.

To make the egg float you simply make the water heavier by increasing its density using a soluble substance such as salt. So our hypothesis was that we can make an egg float in 3 liters of water with 2 table spoons of salt. Why does the egg sink in regular tap water but float in saltwater.

You add a known amount of your starting or stock solution to a known amount of water and mix them. Floating an egg in a beaker of water is a classic science project that illustrates archimedes principle. Using the results of your experiments draw conclusions about the density required to make an egg float the density of seawater and the interaction of other materials with salt and the egg.

When you lower the egg into the liquid it drops through the normal tap water until it reaches the salty water at this point the water is dense enough for the egg to float. In this science activity you figured out within a factor of two how much salt it takes to float an egg.
