Regular Ice Cubes

Some of the first things that come to mind when people think of energy are high level experiments that are conducted in labs. However, energy is just what is transferred from one object to the next when a reaction takes place. Energy is constantly being used in everybody’s daily life. Whether they know or not, everyone is constantly using some form of energy. Everything from walking, eating, and sleeping are all utilizing energy in different ways. Even applying ice to keep a glass of water cold is exerting a form of energy (“Heat Transfer”). Just like everything else, even ice releases a form of energy when put in water. This type of energy is a mix of convection and conduction. Convection is when thermal energy is transferred from one hot …show more content…
An experiment of testing whether regular ice cubes or plastic ice cubes keep a glass of water cooler for longer will prove how energy works in daily life. For the investigation, two glasses of water will each have a different type of ice placed in them. One will have regular ice cubes while the other has plastic ice cubes. Both will use convention and conduction energy, but it won’t know until after the experiment which form of ice keep the water cooler longer. The independent variable in this experiment would be the type of ice cube being used. In this case, the type of ice cubes being used are regular and plastic ones. The dependent variable will be the temperature of the ice cubes. Finally, the controlled variable will be the amount for water poured in the glass and the amounts of ice cubes used for each glass. The expected outcome of the experiment is that the regular ice cubes will keep the water cooler longer. This is because due to convection and conduction energy the ice will melt and mix with the water. On the other hand, the plastic ice cubes will also melt, but since the previously frozen water is contained inside the plastic it will not mix with the original water inside the glass. Therefore, causing the water to be kept cool for a shorter period of time. Lastly, it is time to test the …show more content…
Both glasses of water were 50 °F. Next, I gathered eight regular ice cubes that were 25 °F and eight plastic ice cubes that were 25 °F. Both glasses of water ice were left in a room that was 68 °F. For the next hour I used a thermometer to check the temperature of both glasses every two minutes. After the ten minute mark, I waited and only checked the temperature of the glasses every fifteen minutes. I continued to do this for four hours and thirty minutes and then concluded the experiment even though not all of the ice had completely melt. As shown on my data table (located on page four) both types of ice cubes kept the water a steady and cool temperature for a long time. They also both were extremely similar in temperature for most of the experiment. However, it did show that the regular ice kept the water slightly cooler than the plastic ice did. As mentioned before, the reason behind the ice melting and keeping the water at a low temperature was caused by convection and conduction energy. The whole investigation showed how these two forms of energy are used in everyday life like putting ice in a drink to keep it
