Do fruits and vegetables have different densities?
Are there different densities for different fruits and vegetables? If they have the different density, does it affect the fact if it floats in water or not? This is the topic to see if it is or not.
First of all, what is density? It means how much something is stuffed in a particular region. (Diagram 1)For example, there is a simple balloon. We can see that there is air inside the balloon. You can squeeze it so it i less dense. If you put sand inside, it is heard to squeeze it. The balloon has more density. The more solid the object is, the denser it is.

I will measure if the fruits and vegetables densities by using water. By doing this, we can see how the dense of the object is. We will put the water inside and then put the object in. The amount of the water that flowed out is the density of the object. (Diagram 2) For the Diagram 2, the water in the bowl is the density of that object. We put the water in the measuring cup and see how much the density is.
Diagram 2: Pouring water that flowed into the measuring cup
The amount of the water that flowed is the density of the object.
If the flowed water is more than another fruit’s water’s amount that came out, the density is different. If the water that flowed is the same, the density of the fruit and vegetables are the same. Then we can know how the density is the same or not. This will be the result for the topic.
This is how to measure the density for a fruit or vegetable with using water. It will show how much the density is easily. Using this measuring skill, you can measure almost anything that you want to measure.
