Whether you would like to carry out a science project on your leisure time, or there is an important science fair that you are preparing for, many enjoy conducting science projects. Carrying out these science projects is a way in which one may discover new things, while having a fun time in its execution. One of the science projects that can be used to accomplish either one of those goals is a science project that is conducted in order to study the effect that temperature has on a chemical reaction. There are three materials that you are going to need in order to carry out this science project. To most accurately carry out this science project, you are going to need a glass, water, a thermometer, and three Alka-Selter® tablets. The science project begins with filling a glass with cold water. From there, you are going to measure the temperature of the water that you have placed in the glass. This temperature is to be recorded on a piece of paper or a chart, whichever you choose. The next step is to drop an Alka-Selter® tablet into the water. Observe what rate the chemical reaction occurs at this temperature, as the tablet dissolves in the water. Then you are going to take note on your paper or chart of how fast or slow the chemical reaction occurred. From there, you are going to repeat this process for the remainder of the science project for a warm temperature, and a hot temperature. At the end of the science project, your observations recorded on the chart will allow you to conclude when it is that a carbon dioxide chemical reaction occurs faster, whether it is with a colder or a hotter temperature liquid.
The next of the science projects is one of the signature science fair projects. This is because it is yet another one of the science projects that has to deal with ice. Nevertheless, this is not necessarily the same as any of the other ice science projects because it is a different conclusion for which is attempted to be reach. That is, this is a science project that is conducted in order to determine what material that is added to ice will allow it to melt the fastest. Although this is one of those science projects that requires several materials in order to reach a conclusion, this is also one of those science projects to which you are able to find most of the materials that you need in your home. In order to begin this science project, you are going to need a bowl, four cubes of ice, salt, sugar, sand, pepper, and a timer. The only material that you may not have in your home in order to begin this science project is sand. However, if you do not have sand, you are still able to carry out this science project. The first thing that you are going to want to do is to put a cub of ice into a bowl. The next step is to sprinkle a tablespoon of salt over the cube of ice. From there, you are going to observe how fast the ice melts. From there, you are going to start your timer. Once the ice fully dissolves, you are going to stop the timer and record how long it takes for the ice to dissolve using salt. You are going to repeat this process for the pepper, sugar, and sand. This is one of the science projects that has a clear conclusion. By the end, you are going to be able to conclude what substance melts the ice fastest.
