The purpose of experimenting with ice and whether salt causes it to melt faster is to see if ocean salinity levels are a factor in the melting of ice caps. I hope to gain a greater amount of knowledge about ice caps and their importance, as well as what humans can do to possibly preserve them. This project can be valuable to society because it will show what kind of impact we may have on Earth and what we can do to maintain the ice caps in our world. It can also demonstrate the long term effects of high water salinity in Earth's oceans. My procedures were to compare the melting times of ice in cups of water, each with different amounts of salinity. I measured how long it took for ice to melt in each cup for a total of five times, and then found
For our lab, we have six beakers of water. Three of the beakers contain high temperature water that range from 46 ℃ to 55 ℃, while the other three beakers contain room temperature water that range from 22 ℃ to 23 ℃. Then, we take six different colored Alka Seltzer tablets, and place them into the beakers one at a time. We record the length of time it takes for each Alka Seltzer to dissolve
Taking ice cream outside on a warm day and then on a cold to see if warm weather affects the melting of ice cream would be the experimental approach.
I started with controlling my experiment environment. It was in a still kitchen, with no appliances running to minimize humidity and control the room temperature. I then broke my ice cube tray and finding cubes that weight .10grams. I set up my timer for each station. I put three-.10gram ice cubes in a identical contained on top of the pre measured ½ teaspoon of sugar, salt and baking soda, then I hit start on the timer. When the timer hit 15 minutes I picked up each ice cube and put it on another dry identical dish. I then measured the melted liquid, followed by measuring the melted ice cube alone. I repeated this three times to get an average.
The experiment will start with two ice cubes. One will have nothing added to it, the other will have ½ tsp of salt sprinkled over it. Each will be separate on two different plates/containers. Time will be kept with a stopwatch, and notes will be taken throughout the experiment on the percentage of ice that has melted at certain points in time.
World War Two resulted in a chaotic destruction that overwhelmed Europe. These feelings of dismay are concisely summarized in Ruta Sepetys’ Salt of the Sea.. An impactful quote states, “war had bled color from everything, leaving nothing but a storm of gray.” The war in 1945 had drained any and all feelings of hope and spirit out of European people. In it’s wake, the war left a cloud of devastation and despair. Florian and Joana have to overcome this war, their fate, and guilt in order to return to their past selves and survive their journey in a German and Russian warzone.
In other words, it takes less energy to raise the temperature of the salt water 1°C than pure water. And in the winter time, adding salt to the ice lowers its freezing point, so even more energy has to be absorbed from the environment in order for it to melt.
Explanation (20 min): The teacher and students will discuss the results of the ice cube experiment. Lecture about the salinity and subsurface topography. Discuss a misconception about the relationship between salinity and temperature of the oceans.
Ocean water desalination is the process of making ocean water drinkable. Seventy-one percent of the world is covered in ocean water, and a significant number of people in the world live within thirty miles of an ocean. Despite the abundance of resources, a large portion of the energy and materials found in the ocean remains largely untouched. Desalination of ocean water is the only solution for countries with a limited availability of existing sources of drinking. Areas such as parts of the Middle East and Africa, where water is scarce, may use outside shipments of fresh water and techniques to purify the abundant ocean water in order to survive. Some areas in South America where water may be abundant, could be unsafe to drink due to the biological
The ice cube in the fresh water melted in 6 minutes and 7 seconds while the ice cube in saline water melted in 17 minutes and 14 minutes. There was more than a 10 minute difference in times between the solutions. Additionally, with the help of the food coloring, we observed that in the beaker containing saline water, there was a clear difference between the food coloring layer of fresh water and the clear water layer of saline water. However in the fresh water, the food coloring spread throughout the entire solution with it mixing
The result of the experiments were credible because it shows the rate ice can meet in the first thousands years and this rate has occurred in the past. I agree with the author’s point of view because as shown in their experiment the dependence of fossil fuels can be hazardous to the ice sheets that will affect our environment. The question this article answered was what will happen to future generations if the ice caps melt. Some additional questions would be how will the rate of melting change if fossil fuels were used less and is there another way to preserve the ice caps. I learned about the importance of keeping balance of our environment and not using fossil fuels to our
Sea ice is important for global climate. It separates the ocean from the atmosphere which is cold. Sea ice influence sunlight’s amount. It is essential for the human activity. In 2015, sea ice distance decreased to 4.41 million square kilometers. In addition it reached the minimum distance on September 11. The extent of sea ice increased through two seasons which was
obal Warming is caused by the built up of carbon dioxide and other air pollutions. These absorb sunlight and solar radiation, trapping the heat which causes global temperatures to rise. Ocean Acidification is caused when the ocean absorbs carbon dioxide from the air causing it to be acidic. Scientist believe that the ocean has absorbed about half of the excess carbon dioxide in the past 200 years. This has caused a drop of 0.1 in ph. Since the pH scale is logarithmic, this change represents a thirty percent increase in acidity.
The hypothesis was that ice will melt faster on metal materials, and slower on other surfaces like wood cutting boards or plastic. My group’s data supported this hypothesis, because the ice cubes put on the metal surface melted much faster than on wood or plastic. The only variable that changed during the experiment was the material on which the ice melted. Other potential variables that my group attempted to avoid changing were the size of the ice cube, keeping the ice cubes identical, how the ice cube is stationed on the material, keeping it flat on the material, and how long the ice cube was in my hand before touching the material. Potential causes of error include holding the ice cube in my hand for too long, not starting the timer at the
The Arctic and Antarctic sea ice is a necessity to the animals currently residing on the ice. It provides necessary nutrients for them to thrive off of, acts as a home for various amounts of species that are suitable to live there, and help keep the water’s heat from adding to the cause of global warming. In conclusion, sea ice is vital to keep the environment
Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives.
