Sugar Investigation \Input Variable Outcome Variable Temperature Time taken for the sugar to dissolve Volume of Water Number of Stirs Amount of Sugar Type of Sugar The input variable we are testing is the temperature to see if the time taken for the sugar to dissolve differs. Prediction I predict that when the temperature of the water increases, the time taken for the sugar to dissolve in the water will be quicker than dissolving at a low temperature. This is because, the particles in a solid are very close together and are in a fixed position. The particles in a liquid are very close but are not in a fixed position causing them to flow over each other. So when a solid is put into a liquid, the liquid particles collide with the solid , causing the solid to get smaller and eventually dissolve. As heating the water, the particles will move more and collide more often with the sugar. This will cause the sugar to dissolve quicker.The particles never disappear they just become so broken down that they cannot be seen by the naked eye. So I think , the sugar will dissolve faster , as the temperature of the water increases. Aim My aim is to prove my prediction above.

(Why Does Alka-Seltzer Fizz in Water?) The fizzing that occurs is basically the same as baking powder and vinegar. (Why Does Alka-Seltzer Dissolve in Water?) The chemical reaction happens when molecules collide into sufficient energy to break old bonds and form new ones. (Walker and Wood)Some of these may take a while and others may take almost no time at all. (Walker and Wood) Alka-Seltzer contains citric acid and sodium bicarbonate which is basically baking powder. (Walker and Wood) I believe that the tablets will dissolve faster in warmer water, because increasing temperature also increases kinetic energy of the reactant molecules. When the rate of the reactant molecules increases the tablets will dissolve quicker. (Walker and Wood) When Alka-Seltzer dissolves it is caused by acid coming in contact with baking soda. (Why does Alka-Seltzer
The Unnatural Causes: Bad Sugar video, discusses the diabetes problem among the Tohono O’odham and Pima Native American tribes. The video also shares information on the destruction of the Native American communities that contributed to the demise of the good health that Native American’s once had. Additionally, the video shares how Native Americans’ food diets were affected by the loss of water. Lastly, there are key members of the Native American communities featured in this video, sharing about their efforts to re-build the Native American communities.
The Effect of Solute Concentration on the Rate of Osmosis Aim: To test and observe how the concentration gradient between a potato and water & sugar solution will affect the rate of osmosis. Introduction: Osmosis is defined as, diffusion, or net movement, of free water molecules from high to low concentration through a semi-permeable membrane. When a substance, such as sugar (which we will be using in the experiment we are about to analyse), dissolves in water, it attracts free water molecules to itself, and in doing so, stops them from moving freely. The effect of this, is that the concentration of (free) water molecules in that environment goes down. There are less free water molecules, and therefore less water molecules to pass across a semi-permeable membrane, through which sugar molecules and other molecules attached to them are too big to diffuse across with ease.
From 1773 to 1775 the Americans felt the weight put to them by the supreme approaches. The mix of the brutal duties and the absence of an American voice in Parliament offered ascend to types of protection which drove thirteen settlements in North America to consolidated to break free from the English Domain, joining to wind up noticeably the Assembled Conditions of America. Before the finish of the Seven Years War there was nearly nothing, assuming any, motivation to trust that one day the American settlements would embrace an unrest with an end goal to make a free country state. As a piece of the realm the provinces were shielded from outside intrusion by the English military. Consequently, the pilgrims paid moderately few assessments and
One of the leading factors in the growth of the sugar trade was the ideal land in the Caribbean for the growth of cane sugar. After the discovery of the Caribbean in 1492 by the Portuguese, colonies began to pop up in every island. Countries such as France, Spain, and Britain controlled major islands such as Jamaica, Cuba, Saint-Domingue, and Puerto Rico in 1750 (Doc. 1). These countries also colonized surrounding islands. The more intriguing fact is the climate data in Document 2. The ideal latitude range for cane sugar production is between 37˚ N to 30˚ S. Looking on the map on Document 1 and on the second chart in Document 2 confirms that the islands in the Caribbean are in this range. Other factors such as rainfall, soil type, and temperature
We are all aware of sugar, the sweet delicious substance commonly used in food and beverages, but table sugar is not the only sugar there is. There are many artificial sugars that many people now-a-days aren’t aware of. In this research paper I will be identifying four different types of synthetic sugars which are: Saccharin, Aspartame, Sucralose, and Sodium cyclamate. Synthetic sugars, or artificial sweeteners, have both positive and negative effects that can either make a big impact in our body or a small impact. Synthetic sugars can be used in many ways but are most commonly used in regular everyday foods and beverages or they can be mixed with other artificial sweeteners. Synthetic sugars tend to look very similar to real sugar so sometimes it may be hard to distinguish them with the naked eye.
Overall numerous individuals think about Ernie Barnes due to his acclaimed painting entitled "Sugar Shack". This sketch was shown on the famous sitcom "Great Times" and was additionally used as a collection cover for the late however extraordinary Marvin Gaye's collection "I Want You". This depiction, be that as it may, was made in the mid 1970's yet never gotten any national or universal introduction until the "Great Times" TV arrangement began exhibiting it toward the finish of every scene and Marvin Gaye collection uncovered this exceptional bit of craftsmanship to a standard crowd. "Sugar Shack" is known for having a noteworthy impact in the formation of the "Dark Romantic" kind of craftsmanship. This class is frequently viewed as the "visual craftsmanship likeness the Chittlin' Circuit". Ernie Barnes even expressed in an uncommon meeting from 2008 that "The artistic creation transmits mood so the experience is re-made in the individual survey it. It demonstrates that African-Americans use musicality as a method for settling physical pressure."
The increase in temperature will therefore increase the rate of reaction. As this is the variable I am measuring I will not keep the temperature constant and therefore I will be varying it. Volume of water- if the volume of the water is increased there is more likelihood that there will be more collisions.
5.) One at a time, place your test tubes in the water bath and heat the first test tube to 25 , the second to 50 , the third to 75, and the last to 100 degrees c. Remeber to stir with your stirring rod every so often.
In a 250ml beaker place 100mls of water, measure the temperature of the water and record this initial temperature onto a table. Set the timer and add one teaspoon of Ammonium Nitrate to the water, stir this continuously until the Ammonium Nitrate has dissolved. After 1 minute measure the temperature and record it, do this for a further 2 minutes (3 minutes in total). Repeat this process for a total of 10 teaspoons.
Probably some of the most pleasurable and enjoyable memories of a person has to do with sweets. When thinking back to birthdays, there is always the memory of the wonderful cake that mother beautifully made and decorated with frosting and glazes. A typical night out with dad can be transformed into a magical evening with a trip to the ice cream parlor. The end of a fantastic Thanksgiving dinner turns heavenly when a hot apple pie is brought to the table and topped with delicious, melting vanilla ice cream. A good wedding is never complete without the cutting of the splendid multi-level wedding cake, when the happy new couple gets to playfully shove and smear cake and white frosting into each other’s smiling faces. Everyone knows that as a child, the only good part about going to the dentist is getting the candy bar at the end of the visit. Why do some people get sick after eating too much suger? Some people do not even know that the abuse of sugar can lead to negative effects on your body. There is something strangely enjoyable and resplendent about the consumption of sugar. Why is it that sugar is so deliciously enjoyable and at the same time a food product that has many negative affects on people’s health?
When asked the question, “What was the most significant revolution in history?” to an English speaker, most people would respond with a political revolution such as the French Revolution, American Revolution, or the Russian Revolution. A few people would respond with other revolutions such as the Industrial Revolution, the Renaissance, or the Reformation. The commonality between all of the revolutions listed above is that all revolutions have resulted in direct changes in the Western World. This is a result of ethnocentrism, considering one’s culture to be superior to others. However, there are many revolutions that have occurred mostly outside of Europe. An example would be the Sugar Revolution, “a series of interrelated changes that altered
For my preliminary work, I used a 50 mm piece of potato. It was easy
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
...r 15minutes. I would keep the method the same as I did doing this investigation but try a salt solution instead of sucrose as it would be easier to make different concentrations by having a certain amount of salt per 100cm³ of distilled water.
