Science Fair Project On Oranges.

Have you noticed that a lot of foods that you buy at the supermarket are actually dried (the water is removed from it)?  Drying foods can help keep it from going bad quickly and it can make it easy to store and easier to use.  Fruits and vegetables are less likely to be dried, because they are filled with a lot of water.  In this science fair project, one of our Science Fair Projects Grade 1-3,  you are going to answer the question: how much of an orange is actually water? 

This science fair project is perfect for a grade 1-3 class to do together or for parents to do with their children.  Do you think that an orange is made up of more or less than 50% water?  Before starting your science fair project, you are going to want to make your hypothesis.  Your hypothesis is whether or not you think that an orange is more or less then 50% water. For help on all the scientific "Jargon" I recommend "Super Science Fair Projects."

After you have written down your hypothesis, you're going to need to get all of your materials, that you need for this science fair project, together.  The things that you need for this science fair project are an orange, a knife, a paper plate, aluminum foil, and a scale.  The first thing you're going to do is weigh your orange.  Make sure that you write down your measurements in your notebook.  You are also going to weigh the plate and the aluminum foil separately, and write these weights down as well. 

With the help of your teacher (or your mother or father), you are going to cut the orange into thin slices and spread them out on the aluminum foil.  Now, you are going to want to dry the orange slices out by putting them in a warm area that still gets some airflow to it.  For most oranges, it should take around 8 to 36 hours to dry the whole fruit out.  You will know it is dried out when there is no more juice in it, and the orange slices look shriveled and hard. 

When the orange is finally dry, you are going to weigh the slices and see how much weight they have lost.  Make sure to remember to subtract the weight of the foil and the paper from the total.  To find the weight loss, take the dried weight and subtract it from the original weight.  Take a look back at your hypothesis?  Was it right?  Was over half the weight of the orange water?  If you are doing this project with other students in your class, compare the results with them.  The more experiments you do, the better your results will be. 

When we learn these results it just shows you how much water is actually in an orange.  If you can imagine that a lot of other foods have a lot of water in them, you'll just see how important water is to our bodies and to the food that we eat.

Science projects are fun! I hope you enjoy all the science fair projects we have for you. I hope you do a great Science Fair Project. Do have a look at some of our other Science Fair Projects Grade 1-3!

As Science Fair Projects need to be done correctly using the proper scientific method, I strongly recommend that you get one of the excellent e-books I recommend, and make sure you do the best Science Fair Project possible! Browse them and decide wich one suits your needs the best. Personally I think "101 Easy Science Projects" are great because it has projects suitable for all the grades. On the other hand if your project is due shortly, you may want to consider "24 Hours Science Projects." Then again, "Science Fair Projects Made Easy" and "Super Science Fair Projects" teaches you all the scientific methods and both have lots of help to ensure you do the best project possibe, so, have a look, I know you'll not be dissappointed.
