Density was dated as far back as the first century BC. The Greek philosopher Archimedes had to find out if King Hiero’s goldsmith was stealing gold and replacing it with a cheaper metal in a valuable object. When Archimedes was taking a bath he realized, that he could determine the volume of the suspected object by the amount of water it displaced.Then, by dividing the weight
(mass) by the volume, then comparing the resulting density with that of gold, he could determine if the object was gold or a cheaper substitute. According to legend, the thought so thrilled
Archimedes that he ran through town shouting “Eureka!,” a Greek word meaning “I have found it.” Density has its own formula known as mass/volume . Every substance has its own density. The density of a substance never changes, unless there is a change in the pressure or temperature. If the object is solid its volume is cm and if its liquid its volume is mL.If the object is irregular then they would have to use something called the water displacement method to find the density.Submerge the object, then measure the volume of the water displaced and then find the mass and finally using the the density formula. Density is a really useful source to everyday use. For example, building a ship; you would not want to use materials that would sink in water.
Some fun facts about density: Earth scientists use density measurements to identify minerals and other solids. Chemists measure the density of a solution to determine the concentration of a substance in that solution. A can of diet coke would float in water unlike a can of regular coke. If saturn was to be put in water it would float, the density of saturn is 0.687 g/cm
The Earth has the density of 5.513 g/cm . Mars has the

Science Report On Rate Of AC

Science Report Production of AC AC is short for alternating current. This means that the direction of current flowing in a circuit is constantly being reversed back and forth. We aim to produce AC by, connecting the copper coil by a clamp onto the retort stand, having a magnet attached to the end of the spring hanging off another retort stand, enabling the magnet to move in and out of the coil, thus producing an AC. Hypothesis We predict that the data received and transmitted to the computer…

Science Report Abrasion Essay

Ava Altmann 1/6/13 Magalloway Rock Abrasion Science Report Purpose: What effect does the length of time of abrasion have on the way rock particles weather? Rocks are constantly changing their size because of the weathering process. Weathering is when rocks are broken down by physical or chemical means. An example of physical weathering is abrasion. Wind, water, and gravity can cause abrasion to happen. For example, in a stream, the current pushes rocks forward, causing them to hit and rub against…

Kai-Nt1310 Unit 1 Assignment

Kai-Jun has shown a strong understanding of the content and knowledge related to our science topics. He was very successful on our first exam about scientific discovery and scientific process. In other areas of the course he is less successful because he does not always follow directions on assignment rubrics or complete all required areas of lab reports or projects. He can improve in this area by using his class time more effectively and checking his assignments against all areas of the rubric…
