Its purpose is to gain marks in the subject APL. Objective: To measure the buoyant force of different objects using Archimedes’ principle. Hypothesis: When the object was immersed in the water its weight should decrease due to the force exerted by the solution on the object. The weight of displaced solution will be equal to the weight of the immersed object. …show more content…
The principle states that upward buoyant force, which is exerted on a body immersed in a liquid will be equal to the weight of the liquid that the body will displace. (Density of object)/(Density of fluid)=(Weight of fluid)/(Weight of displaced
In conclusion, the dime was able to pull it off and hold more drops than the penny. My hypothesis was incorrect because, I thought the penny would hold more drops than the dime because the penny was bigger and I thought it would absorb more. But the dime held more. Preston and I even ran the tests or investigation three times for each coin. The one question I had was ,what if the penny was stacked 1 time and the dime was stacked one time,would it make a difference ?
Density is the calculation or equation of mass divided by volume and it can be used to identify different substances. Density is always the same in one object or substance because density is a constant ratio. Objects have “lighter” densities will float while objects that are “denser” will
Next, I removed the water and the quarter from the graduated cylinder and poured 50 mL of water again. I repeated this until I got results for all three coins. To find the volume of each coin, the formula I used was volume of water and coin - initial volume of water ( 50 mL ). To find the density, I divided the mass and the volume of each
The final article of the three that uses the technique of

Starch solution is then placed into the test tube at a quantity of 5 mL. 5 drops of Lugol’s Iodine solution is added to the test tube. If the color changes, then it is known that starches are present in the solution. Proteins are next tested. In order to do this, 5 mL of gelatin solution is added to the test tube. 10 drops of Biuret’s reagent are added to test for protein.

On our paper we predicted the amount of pennies that could fit in the boat before it sank. We tested the boat in the water and added pennies one by one. We then calculated the mass of pennies that fit in the boat and the density of it. The purpose of this Lab was to make a boat that holds as many pennies as possible and understand how to calculate
When this is completed the hypothetical hydrostatic pressure and expanse to the middle of pressure can be deliberate. From this one might associate the theoretic standards to the real standards restrained. The percentage alteration is then dogged. The percentage alteration amongst the restrained and theoretic forces was nearly almost zero for all increases. We did have some inconsistency amongst the dignified and hypothetical complexities to the middle of pressure.
Uncontrolled Environmental conditions Atmospheric conditions The controlled variable Concentration of amylase was kept under control by measuring the amount of amylase used and also it was made sure the percentage of amylase used was 1%. The Amount of amylase/starch used were kept to 5cm3 at all times. Materials needed Beakers Bunsen burner Test tube Thermometer Stopwatch Test plate Glass rod Starch Amylase solution Water bath Iodine solution. Test tube holder Labels Marker Procedure First 5 test tubes were taken and labeled with numbers from 1 to
The text is divided into four sections, each with a distinct focus related to the cyclical nature of the process of data collection, analysis, and evaluation.
