The experiments that have more than one day to complete are not suitable to expose in science fairs that are organized for a single day. The experiments that can be completed in a day are always better options for students participating in international exhibitions. Unlike experiments with three or four days to the end, science projects fair a day are short and easy to perform. You may end up in a day with accurate results and a conclusion. Even if you are required to submit the full report, you will have enough time in hand to achieve a concise thesis.
A Day of Science Fair Project Ideas
Determining the boiling point of water under different conditions is a wonderful idea for a Science Day fair project. We all know that pure water boils at 100 ° C. But have you ever tried to notice the difference in the boiling water when solutes are added to it? Why not experience this on their science fair project? Take three cups and fill with water. The first glass contains clean water while in the second beaker, add a pinch of salt to the water. The water in the third container is mixed with a teaspoon of sugar. Label each bottle to avoid confusion. You can insert a thermometer in each container separately for measuring temperature. Now record the temperature and note that its registration practices. You will notice that the temperature of boiling water containing dissolved salts and sugar is higher than that of pure water. Explain the experiment and logical reasons and to create an excellent working project.
Dry Ice Experiments
Students find dry ice experiments very nice because they are easy to perform and can be finished in one day. So what is dry ice? Carbon dioxide in the frozen state with a temperature of -109.3 degrees F is the dry ice. Common experiments carried out with dry ice are the inflation of a balloon, so that sources of smoke and pop cans. Creating a source of smoke or cloud drops is an excellent work project that could be done easily. You need a hot tub. Make sure you are wearing gloves when handling ice cubes and then dip into the water. You will notice that the ice sublimes gradually issuing large amount of heavy vapors. These vapors are suspended in the air and they look exactly like white clouds. A balloon may also be inflated with dry ice. How? Stretch the mouth of a limp balloon and insert some small cubes of dry ice in it. You can suspend the balloon in a container of warm water or rub with the palm. The heat generated will cause the pellet to give off vapors that inflates the balloon. You can write your project work with an appropriate explanation and observation.
The identification of microorganisms
Project work related to the identification of microorganisms can be performed in a single day that are supplied with samples of bacteria that have been grown. You must have studied the properties of the different species of bacteria that are easy to detect under the microscope. To conduct this experiment, you will require glass slides to see the bacteria under a microscope. Clean the slide with ethanol and air dry. Make sure that no fingerprints on it. Now scrape a small amount of bacteria in the samples provided with the help of a wire loop. Spread the sample on the slide and then stained with patches supplied. The spots that are commonly used for identification of gram-negative and gram-positive are safranin and iodine. Then set the fire bacterial smears. The experiment should be carried out in accordance with the measures foreseen in the protocol. View the slide under a microscope and identify bacteria according to their staining properties. Then show the observation with appropriate schemes and logically explain the observations.
Vitamin C in fruits
We all know the importance of vitamin C in our body. Citrus fruits are rich in vitamin C and can use this concept for the comparison of the amounts in different types of citrus fruit. Juice of an orange, lemon and grapes and berries. The steps to perform this experiment will be provided in the protocol. However, you can follow these steps. Make a paste with a tablespoon of cornstarch in water. Dilute solution by adding 250 ml of water and bring to the boil for 3-5 minutes. Pipette 75 ml of solution in a beaker and add 10 drops of starch solution to it. The indicator used is 2% iodine that is added to this solution to obtain a rich purple. Now transfer the starch-iodine solution in 4 test tubes, each with 15 ml. Pour 10 drops of fruit juice in each test tube and observe the color change. The fruit contains the highest percentage of vitamin C will fade the color of the indicator solution harder. The same concept can be used to find out the nutritional content of different types of food.
You can use the concepts explained in this article for their projects in a science fair day. Since time is less, must find the topics that can be completed quickly and that do not require much labor. Organize everything in order with an appropriate explanation and give a presentation that will be applauded by all.
