For this year’s science Fair, introductory Physics college student Shae K. Started by pondering whether it would be possible to identify a an enig sample of various minerals by formulating their density, given the expertise that a certain substance’s thickness will stay unchanged regardless of a adjust in that is mass. Due to the truth that minerals do not frequently come in perfect cubic form, Shae realized the in stimulate to take a an accurate measurement of every minerals volume (needed to calculate density) he would have to utilize the water displacement method. Fascinated by this rather distinctive (and really fun!) form of quantification, Shae traced the beginnings of this method to Archimedes and also his famous bathtub story. Throughout the fair Shae enthusiastically debated the vital tools necessary to carry out the an approach and the procedure involved. Additionally, he presented his visitors v information about minerals, and also discussed the worth of knowing the density of a substance.

You are watching: What is the density of a mineral

### Scientific question

Can a sample of different minerals be established by finding your density?

### Hypothesis

I think that minerals have the right to be figured out by your density.

### Background Information

What is Density?

Density is how much stuff things has in the volume. The object"s density will never change. If you have actually a whole coco cake and cut it in to pieces no issue how plenty of times you cut the cake its thickness will never change.

What is the Water Displacement Method?

The Water displacement technique was uncovered by a man named Archimedes. Archimedes was offered the task to discover out if the gold grown wreath that was given to the king to be made of 100% gold. As soon as Archimedes was acquisition his day-to-day bath, he stepped into a cold bathtub of water to which the water started to spill the end over the sides. Noticing this Archimedes started to watch the water level rise and also over flow, together he submerged into the water. He uncovered the solution to the king problem. The ran the end of the public baths, shouting every the means home, “Eureka!”

He was so excited he forgot that he had no apparel on. “Eureka” in Greek translates into, “I have discovered it.” He found how to uncover the volume of an irregular shaped object.

What is a Mineral?

A mineral is something the is developed by the earth and also not by plants, animals, or people. Coal is no a mineral; it is make from decomposed tree that have actually been fossilized.

How perform you uncover an Object’s Density?

You can discover the density of things by acquisition its mass, i m sorry is how hefty it is, and dividing that by the volume, that is size.

What is Water Displacement?

Let"s say you have actually a cup that water that is filled half way. Climate you drop part ice cubes in the cup. Then the water rises up because the ice cubes displaced water. The amount of water the is displaced is same to the volume that the object. By catching this water and measuring it, using a i graduated cylinder, you have the right to find precise measurement. You can use this number in the thickness formula, i m sorry is mass separated by volume.

Conclusion

My hypothesis was that minerals have the right to be determined by your density’s utilizing the water displacement technique and the is true. If friend look at a mineral graph you will check out the surname of minerals, and their densities. As soon as you put an object in water the water will rise. The reason for this is since the the the objects volume. If you take something that has volume the 10 cubic centimeter the water level will increase by 10 ml. Dropping minerals in one overflow tank fill beneath the spout will certainly make the water rise leading to it to go the end the hole. In conclusion the identification of a mineral and its thickness can be uncovered using the water displacement method.
