Easy Science Fair Projects

This is one of our easy elementary science projects to show the effect of oil pollution on sea life. (On all aquatic life.) It is horrifying to see what oil is capable of doing and this experiment will show the kids that all the worrying about oil spills in the sea is not exaggerated and that it in fact has devastating results. This easy elementary science project is also very suitable for homeschoolers.

What you need for this experiment:

• 4 Hard boiled eggs
• 4 Sealable plastic bags
• Water
• Food coloring
• Motor oil or other wise olive oil as a substitute
• Felt marker
• A watch or a timer
• Some masking tape

What to do:

1. Take your 4 bags and mark them 1, 2, 3 and 4.
2. Now you fill each bag with ½ Cup of water and ½ Cup of your oil.
3. Drop a few drops of food coloring into each bag, mix it well with the oil.
4. Take your hard boiled eggs and place them in the bag.
5. Now you remove the eggs from the bag as follows
#1 after fifteen minutes
#2 after half an hour
#3 after an hour
#4 after two hours
6. Each time you have removed the egg from the bag, carefully peel the shell off the egg.
7. Write Down your observations.
8.  You will notice that the longer the egg stayed in the oil, the more oil got inside the shell of the egg. (The food coloring makes it easy for you to see that.)
9. Remember to make accurate notes of everything you do and it is best if you also take photos of the results for your display.

Doing Elementary science fair projects need not be a problem. There are tremendous e-books available that gives you all the ideas and information you need. I find 24 Hours Science Projects very good as it gives you complete experiments from hypothesis to conclusion that can be done in 24 hours or less. This is important because it prevents your home from being taken over by the project for months on end.

Examples Of Science Projects – Fun Experiments On Liquid Density

We have a number of short Examples Of Science Fair Projects. In this short easy elementary science projects we are going to see some of the interesting things that happen because of the density of liquids. The density of and object has to do with how tightly packed the object is. Two objects can weigh the same but one is smaller than the other, the smaller one is packed more tightly and is therefore denser than the other object. These experiments are meant to make learning fun and are also very suitable for homeschoolers.

The floating egg experiment

What you will need for this easy elementary science project:

• A container
• Water
• An egg
• Salt
• A spoon

This is what you have to do for this easy experiment:

1. Fill the container with enough water to cover the egg completely.
2. Carefully place the egg in the water.
3. What happens to the egg?
4. Make a note of what happens.
5. Start adding salt to the water and stirring it very carefully so as not to break the egg.
6. Keep on adding salt until your egg starts to float.
7. You will need quite a lot of salt, about 4 tablespoons full of salt per 1 ½ cup water to make the egg float.
8. Now you add water to your solution again until the egg start sinking again.
9. Keeping density in mind, try and explain what just happened.

If you worked carefully and did the experiment the right way your egg started rising because it became less dense than the water when you added the salt. When you added extra water, the water once again became less dense than the egg and the egg started sinking again.

This is one example of our easy elementary science projects, one of many examples we have of science fair projects.
