How do you do the science project about salt water making an object float?

In short.
Select an object that would just sink in water. Then using identical sized containers pour an equal amount of water into each, say 3/4 full.
Then in each dissolve an increasing amount of salt, from no salt in the first, to large amounts of salt in the last.
Then place the same object into each container, starting with the "no added salt" water to demonstrate it would sink in this. Then into the increasing concentrations of salt. If it is suspended in the salt solution and not the first "no added salt" water, you're proven salt water helps objects float

How much water should you use to make an object float?
That depends what object you want to float.
Why does a dense object float in the Dead Sea?
An object float in a liquid only when the density of the solid is lower than the density of the liquid.
How is specific gravity defined in physical science?
It is the laboratory, or service station, measurement of an object's (including Fluids) Density based upon it's ability to float a test material.
An object that does not sink in water?
The ability to float in liquids is called buoancy. It is regularly demonstrated by wood, which is less-dense than water, and will float (in most cases). If an object is too dense, or its weight is not distributed over a large area, then it will sink.
Would a substance float if its density is 1 gram per ml?
Less than that of the substance it is floating on.
Where do you find the science fair project called egg flotation?
Science Buddies has a project called: How Salty Does the Sea Have to Be for an Egg to Float?
What is a good a object that will float holding marbles?
A good object that will float is a plastic container. It worked for me. Yes a plastic container will work well it worked in my science class.
What are some good titles for a science project on how much salt does it take for an egg to float?
The Buoyancy of an Egg
How many salt concentration is needed to float an egg this is 4 a project in science buddies. httpsciencebuddies.comscience-fair-projectsproject ideasOceanSci p003.shtmlfromHome?
If it's for a science project, then discovering the answer is the fun part!
Why does salt makes an object float?
it increases the density of the water, making objects float easier. ex. the dead sea.
When an object float what does the object have?
when a object float it has density
What happens to an object when it is placed in a less dense liquid or gas?
The density of the object goes through the less denser liquids until it gets to a liquid that is more dense than it. The first liquid that is denser than the object, the object will float on the liquid. My class did this in Science Class.
How do you make an egg float in the air?
The higher the salt content in water the more an object will float. Check the related links for a science experiment that will also help you to experience how this works.
If the density of an object is 1 then will that object sink or float?
The object would float in the middle if it was in water.
What does results mean in a science fair project?
it means like what happened when you were testing your science fair project so for an example if you did how salty does the sea have to be for an egg to float on water you have to say what egg floated and how much it weighed
What factors determine how heavy an object can be and still float?
An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.
Can a potato float on salt water?
Yes it can, if you put a lot of salt in the water. You'll see that it works it works for a great science project!
