Science Fair Project Ideas If you’re looking for science fair project ideas you came to the right place! On this page you will find several ideas for cool science fair projects‚ for kids of all ages. These projects are particularly interesting because they have practical relevance in real life‚ and you can use common everyday materials to create them. These project ideas are mostly physics based. For the most part I have worked on these projects myself‚ and have included pictures for your benefit

Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab‚ the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum‚ which one can use to identify them. For example‚ NaCl was highlighter yellow‚ Sr(NO3)2 was sun orange‚ CuCl2 was turquoise‚ LiCl was neon red‚ KCl was solar flare yellow‚ and BaCl2 was Voldemort green. Introduction- In Bohr’s

for some chloride salts‚ including sodium chloride (NaCl)‚ which are used as de-icing agents on roads. The application of these de-icers on roads and other impervious surfaces in North America during winter months was in practice since the 1960s. The amount of snow fall is so high in these areas that snow and ice management becomes very essential to prevent road accidents‚ to maintain a continuous flow of traffic and to ensure safe pedestrian travel during winter months. Sodium chloride is the most

Guide Questions Experiment 1 Calibration of the calorimeter: 1. Give the net ionic thermochemical equation of the reaction used to calibrate the calorimeter. a. Is the reaction endothermic or exothermic? b. Which is the limiting reactant? c. How much (in moles) limiting reactant was used? d. How much heat was generated (or absorbed) by the reaction? 2. Relate the sign of the ΔT to the ΔH of the reaction used for calibration. 3. What is the heat capacity of the calorimeter? Relate

Part Ca)Up until the 1940’s rubber had only been obtained from the latex of rubber trees(Hevea brasiliensis) in plantations situated in tropical areas such as Malaya and Burma. The demand for rubber increased significantly during world war 2 as rubber was needed for tyres of military vehicles and the supply was interrupted by the conflict between the countries. Scientists in Germany and the US developed synthetic polymers that could replace rubber. Even after the war ended the traditional sources

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

Since sodium chloride and water have both been lost due to sweating‚ substitution of both is key to restore the blood volume back to normal. In people who become unconscious during heat shock‚ intravenous infusions of 0.9% sodium chloride are

and put in a data table. The crucible content was then added into a 400 mL beaker and 200 mL of deionized water was also added in to the same beaker. The contents were mixed together until the unknown carbonate was fully dissolved. 125 mL of calcium chloride was then put into a 250 mL beaker and then was added into the 400 mL beaker with the unknown carbonate and water. The precipitate was settled for five minutes. Next the mass of a dry filter paper was recorded and put in a data table. To set
