Have you ever noticed that salt is sold in the store when we have snow and ice on the roads? If you have ever wondered about salt and what effect it has on water. If you put salt on the frozen ice in the road it seems to melt so does it keep water from freezing? You have just discovered a science project for the school fair.
Science projects are right under our noses and can be as simple to find as looking at what we do every day in our lives.
This experiment will not cost you anything except a little bit of ordinary table salt.
Get together 3 containers that you can put water into and freeze. They should be plastic that will freeze well. Also you do not want them to be too large. If you can use a sour cream container or a few small plastic cereal bowls that works well.
Fill each container half full with water from the faucet.
In the first bowl put in 2 teaspoons of salt and stir well to dissolve most of the salt In the second container put in 1 teaspoon of salt and stir to dissolve In the last cup only have water and no salt.
Make sure the water is room temperature.
Now place them all on a baking sheet and place in the freezer in a stable place that will not tip over.
Leave these there all day or over night. In the morning remove the containers and make a visual observation.
Were all the containers frozen solid? If not were they somewhat frozen? Did any not freeze at all?
Did the amount of salt in the water effect how much the water froze?
Make sure to document your information and take photos. This project is not a demonstration that you can do immediately at a fair but you can show what happened to the salt and water combination in the science project.

Kids Science Project for 7th Grade
April 30th, 2010Quick Science Fair Projects For All Ages
April 27th, 2010
A quick science fair project can be less time consuming and it will not be too taxing for an eager student to wait for the results or target of the experiment to emerge. Also, a science fair project should be interesting and inspiring to a student. If the project is due and if time is running out, a quick science fair project can be done. Step-by-step instructions with tips prove to be of great help. The ideas for a quick project can be had from books, internet, TV programs and newspapers; or it can be one’s original idea. Either way, a quick science fair project is just as valid and has just as many reasons it can succeed as a long, in depth study, though you do need to follow the basic guidelines.
To give a jumpstart to your project, you must first get all the materials needed ready before starting. The materials needed for a quick science fair project must be easily accessible from home, naturally (in your backyard, for instance) or a local shop. Always keep in mind that your experiment should be based on scientific principles. Instead of just displaying a project that someone else has already done, consider adding personal input to make yours stand out and be much more meaningful. Have a clear idea about what the judges will be looking for. This will help you to refine the experiment to score good grades.
The student’s experiments are demonstrated for the audience who are usually from other local schools and parents of students. Projects should benefit them and also be of interest to them. The judges will also be looking at the utility value of the conclusion or the results of your study. These are the people who are doing the voting on the projects, and they are the ones you must impress if you have any plans of winning the science fair. If you do it right, there may be scholarship opportunities or other prizes available to make it worth your while. Even without a prize as a motivator, you still need to earn a passing grade, and you can’t do that without interesting the person to whom you are presenting.
The science fair encourages the students to demonstrate the scientific methods with the help of experiments. They encourage originality and creativity. The project can be chosen from any area of science; like biology, physics, chemistry, etc. Some have to be repeatedly experimented to check for consistency before displaying it in the fair, though in a crunch, this does not need to happen for a quick science fair project. Avoid selecting such projects that will be time consuming which may not be in a position to sustain the interest. Anything involving plants or animals should not be considered if a project needs to be done quickly.
Before starting the project, make a timetable and stick to it, as time is of essence for a fast experiment. For electrical experiments and chemistry projects, seek safety advice first. Plant growth experiments need growing conditions and can take a considerable amount of time. Unfortunately, these will not be suitable for last minute projects. Regardless, there are still many options to consider and plenty of information available in books or on the internet if you know where to look.
Quick science fair projects must have a solid abstract. It includes the title and purpose of the project, hypothesis, procedure, result and conclusion. Ideas for quick science fair projects can be searched on the web, and there are many paid guides available for download that will lay out, step by step, a quick science fair project that can be completed and written up in an afternoon. A hypothesis can be proved right or wrong by scientific methods. Importantly the student should be able to understand this and explain their project in his or her own words.

Science Fair Project Topics For Winning Science Projects
April 8th, 2010
There are countless science fair project topics. To figure out a topic, you must first decide on a category of interest; Astronomy, Biology, Zoology, Chemistry, Earth Science, Engineering, Environmental, Microbiology, Physical Science or Mathematics. Once you have found a category that you like, you can then decide on a topic. It may not be an easy task, since there are countless topics on each category, but it will not take you long before you choose something that really interests you. Just remember that any project has the potential to be a winning science project, and keep in mind that the judges are looking mainly at presentation and whether or not you learned something from the project.
You don’t want to pick a topic that is too easy, nor do you want to choose one that is beyond your level. The judges want to see that you are knowledgeable about your project and that you have documented your findings. Obviously, the first thing they will notice is your presentation, so you want to make sure it’s eye catching and well organized. If you use graphs in your project, make sure to double check your figures and ensure you understand the graphs you are presenting. If you can’t explain your work, you are definitely going to lose points. Basically, if you chose a topic that interests you, is on your skill level, that you genuinely learn something from your project, are able to show and explain your work, and present the project in an organized and eye catching manner, you are likely to score great points with the judges.
