Quick science projects are great when you have a limited time frame to complete them or are just looking for a fun way to pass some time on a boring afternoon. There are many options when you’re looking for quick science fair projects, such as how much salt does it take to sink an egg?
All you need for this project is a glass, an egg, water and salt, and you just put the egg in the glass, fill it three-quarters full of water and add the salt, one teaspoon at a time. Another quick science project would to do a food comparison on an animal such as a rodent or a bug, or you could even do it on your own pet. You simply want to find out if they prefer one food over the other. This may not work well for pet dogs though, as most dogs seem to want to eat anything!
You could also do a fairly quick test on depth-perception in humans. All you need is a few cylindrical rods on a table next to each other but at a varying distance from one another, and have a friend cover one eye and try to grab the rod that you specify out of the bunch on the first try. You can then re-arrange the rods and have the friend try to do it with both eyes open. Ask him if he felt he could do it easier with one eye covered or with both eyes open.

Quick Science Projects Made Fun & Easy
April 27th, 20103rd Grade Science Fair Projects and Ideas
April 27th, 2010
3rd grade science fair projects are a lot of fun because at this age children are eager to explore the world around them and find out how things work. They are constantly wanting to know the answer to the question “What happens if I do this…” and therefore they will likely come up with many different experiments they’d like to try. It may be difficult to decide on just one!
At this age they have a short attention span though, so the projects must be simple, fun and fairly short. There are many, many different project ideas for this age group such as; do all the children in their class have the same size hands and the same size feet as each other? They can research this by tracing the other children’s hands and feet on a piece of paper and comparing them to each other.
They could do a test to see if waterproof mascara is really waterproof. To do this you would need a couple brands of waterproof mascara, a piece of paper and some water. Simply put the mascara onto a sheet of paper and rinse it under some water to see what happens.
Another fun 3rd grade science project would be to see if raw eggs and hard boiled eggs spin the same number of times. Obviously they would need an adult’s help with this one in order to cook the eggs, and then they simply need to spin each egg and record the results. There are lots of great 3rd grade science projects out there; it’s just a matter of finding one that interests them.

Kids Science Project Idea – Green Eggs
April 25th, 2010
This science project is unique as you will turn an egg green but how it happens is very interesting and a great demonstration experiment.
Things you will need for the science project.
An egg Red cabbage A pan A pot A bowl Oil A parent to help
You are going to make a green egg and cook it, but you will not be using any food coloring or anything green. Let us get to the experiment and we can discuss the results and hypothesis later.
Take the red cabbage and cut into slices as if you were making cole slaw. You will not need a great deal of cabbage. A cup or two should do the trick. Place the cabbage shreds into the pot and pour in a cup of water. If you are using more cabbage you may want a little more water. You do not need a lot. Turn on your stove top and leave on high or a fairly high heat. Let the cabbage cook for a bit. This could take ten to fifteen minutes. You want to get the water to turn a nice purple red color from the cooked cabbage. We will then use the water from the cabbage. Once the cabbage has cooked and the water is a very dark purple color you are ready.
Take your fresh egg and crack it. Separate the yolk into a small bowl and the white into a little larger bowl. Now take a spoonful of the red water from the cabbage and put into the bowl with your egg white and use the spoon or a fork to stir it up.
Heat up your skillet or pan and place a small amount of oil in the pan as you will be cooking the egg and need to keep it from sticking. When the pan is heated pour the colored egg white into the pan. You will notice the egg white is green. You can also put the yolk on top of the egg white now to cook both together.
This will be cooked sunny side up because you do not want to flip it over as you want everyone to see the green coloring. When done you can obviously eat the egg. There is nothing wrong with it because the coloring was added by the cabbage.
Why did this happen? You took the purple coloring from the cabbage and put it in the egg white and it turned green. You did not have the yolk involved in this. You only added the yolk after the white was cooked to finish the complete egg.
Why did this green coloring happen? What chemical process occurred? Was there any change in the egg shite itself?
This is a great science project for chemistry class in high school.
