Elementary School Science Fair Projects

Taking part in science fairs is definitely appreciated. But when you hold up a science project that is accurate, thought provoking and logically correct, is much more commendable. Get some ideas from this article...At elementary level, you are not expected to work out on a project that will require in depth knowledge in every disciplines of science. Students are usually explained the basic elements of science dealing with physical, chemical and biological changes taking place around us everyday. Understanding the scientific experiments with logic and intellect is important for creating self designed project works. If you are assigned with the task of setting up an experiment or a project then the following list of science experiments will help you out.

Science Fair Projects for Elementary School

Chose a subject that interests you the most for your science fair project. This would simplify your task and capture your interest as well. Whether it's a biology, physics or chemistry project, you have to make sure that your work is understood by everyone. Explain the aim and procedure of the experiment in detail and then draw a logical inference based on your observations. Other than the basic disciplines of science you can also implement earth science and environmental science topics for your project work.

Crystallization Process
Learning how crystal formation takes place in nature is one of the most interesting subjects of chemistry. In this technique, you should first know the chemistry behind formation of crystals and then work on your project with the help of an example. To perform this experiment, you need to prepare a saturated solution, where solute particles are present in more amount than the solvent. You can add sugar or salt for the solute. In order to set up a crystal garden, you have to spread the saturated solution over a substrate. This is required to accentuate the nucleation process. You can use a sponge, rock or brick as a substrate. The other technique is to spread the solution on a plate. Allow the solution to evaporate slowly by exposing to bright sunlight or by placing a heat source beneath it. Once the solution has evaporated you will find that crystals have formed on the bottom of the container.

Transpiration Current
I'm sure you must have thoroughly read the transpiration process in your theory classes. You can demonstrate the same process in your elementary science fair project. You will require a potometer (instrument that measures transpiration current), a beaker, water, a plant having roots and a tracker dye (preferably eosin) for this purpose. The apparatus has two openings. The lower end of the tube is dipped inside the beaker, filled with colored water (due to the presence of eosin dye). The frontal end is fitted with a cork into which the plant is attached along with the root. Make sure the frontal wide end is air tight. You will gradually notice that the colored water travels through the tube. On observing this, remove the tube from the beaker and allow air to pass through it. Insert the tube once again in the water. On doing this, you will observe an air bubble passing through the tube. Transpiration creates a suction pressure due to which air bubble formation has taken place. You can calculate the current by the given formula as you already know the volume of the potometer.

Boiling Point of Water
This experiment is quite interesting for elementary students. To determine the boiling point of water you need to set up the experiment with a Bunsen burner and a round bottom flask. The temperature could be measured easily by a thermometer. Fill half of the round bottom flask with water and place it over the Bunsen burner. Light up the burner at moderate flame. Keep an eye on the water and dip the thermometer inside it. Take the reading when water starts boiling. At least five readings should be taken at an interval of 5 minutes to find out the average boiling point of water. You can compare the difference and change in boiling point of water by adding impurities to it. Add sugar and salt and follow the rest of the process in similar way to take the readings. You will observe that the solution (after adding salt or sugar) will boil at a temperature higher than that of pure water. Citing logical reason, you can infer than the boiling point of water is raised on addition of impurities.
