Youve probably heard of a root beer float but an egg float. This also can be accomplished by adding 1 tablespoon of salt to water and not stirring.

### Control group- cups with less salt Experimental group- cups with more salt.

How much salt to make an egg float. Conclusion So our hypothesis was partially correct the egg did float in salt water but with 18 table spoons of salt instead of 2 table spoons. The ability of something like the egg to float in water or. How much salt does it take to float an egg.

Start with 1 tablspoon and stir it until the salt dissolves. Density refers to how much matter is contained within a certain volume. With enough added salt the saltwater solution density is higher than the eggs and the egg will then float as shown in Figure 1.

We learned that the salt affected the water a lot. Fill the two containers with tap water. The reason the egg can float in saltwater is that saltwater has a higher density than freshwater.

Egg Floating Experiment By. Pour water into the glass until it is about half full. Typically fresh eggs sink to the bottom of a glass of tap water.

Place an egg in the glass of water and see if it sinks or floats it should sink. Some substances you would have to boil to make the water more saturated and denser so. The hypothesis of floating egg in salt water is that salt water and fresh water have different densities.

Can you think of a way to make a glass of salt water with the same density as the egg. Place one egg in each of the containers and observe which one of the eggs float in the container and which one sinks. An egg floats in salt water because salt water is more dense than water straight from the tap.

Answer 1 of 8. You dont really change the volume of the water by adding salt. Dependent Variable- How the egg floats.

A good starting point would be 6 tablespoons of salt in 1 glass of water make sure it is fully dissolved by stirring. In a nice clean container filled with 2 cups of water at least 8 teaspoons of salt are needed to make an egg float. When you add salt to the water you are increasing the density of the water by adding more mass or stuff in the given volume.

Carefully pour in plain water until the glass is nearly full be careful to not disturb or mix the salty water with the plain water. The salt water is more dense than ordinary tap waterand the denser the liquid the easier it is for an object to float in it. The density increases with salt concentration so the amount of salt you need might depend slightly on the egg.

Let us see and do this floating egg science experiment Now let us find behind the reason for floating of egg. Find the minimum amount of salt to float an egg. Controlled Variable-The amount of water and the egg brand and same size cups.

Stir ⅓ cup 80 mL salt into 1⅔ cups 400 mL water until it all dissolves. Since an egg will sink within regular water adding salt to the water will increase the density of the water and allow the egg to float. At that point due to the extra salt in the water it is dense enough for the egg to float.

But when same egg is subjected to glass that contains salt water then this egg floats on water. Add about 6 tablespoons of salt in one container and stir it well with a tablespoon until the salt has completely dissolved in the water. I added about 5 tablespoons then tried it again adding more and more until the egg floated.

Because the salt is denser than the water the salt will sink. An egg usually sinks in water because its density is greater than the density of water. Independent Variable- The amount of salt used.

Fill the bowl or glass about 23 full with tap water. Try it for yourself with this fun videoGet additional ideas and info. If you add less than 1 tablespoon of salt to a glass of water it is possible to make the egg float in the middle.

When enough salt is added to the water the saltwater solutions density becomes higher than the eggs so the egg will then float. Gently lower the egg into the water and watch what happens. The eggs density is only slightly higher than water at 103 gmL but that is enough to make the egg sink.

What is density and explanation5th Grade Science Projects Floating Egg is easy science experiment. In order for an egg to float about 4 tablespoons of salt must be dissolved in 12 to 16 ounces of water. The ability of something like the egg to float in water or some other liquid is known as buoyancy.

So when you lower the egg into the liquid it drops through the normal tap water until it reaches the salty water. Drop the egg carefully into the bowl and watch as it sinks to the bottom. Anyuta Chubok After this experiment I concluded that it takes more of some substances than other to make the water denser that the egg so that it could float up.

When salt is added to water the liquid becomes denser which makes it possible to float various kinds of objects such as kiwis eggs and other less dense objects. Stir in lots of salt about 6 tablespoons. Stir in lots of salt.

Remove the egg and add salt to the water.
