Science Project for Kids To Show Egg Strength

This science project is going to measure the strength of eggs. Eggs are known to be resilient because of their exact shape. The weight is distributed very well around the shell. I will give you several things to test the weight and pressure that an egg shell can absorb.

First get a good dozen eggs. They are only about $1.00 at the store for a dozen. This all depends where you live it could cost more. Test on the egg strength is to see if you can break an egg shell with your hand. Most men will have no doubt they can do this. Make sure the person doing this does not have any jewelry on their hand which includes rings, bracelets and watches.

Place an egg in the middle of the palm of the hand and have the volunteer wrap their fingers around the egg evenly. Do not place this on your hand heel. It goes in the middle or cup of the palm. Now allow them to squeeze the egg. Did it break? If you did this correctly the egg did not break. Why? Due to the shape of the egg and the strength of the shell weight is distributed evenly around the egg and you are squeezing around the full base of the egg.

To test this even further take the egg carton and cut it into 4 sections. Place one egg into each section of the carton holder cardboard and put them in a square about the size of a piece of paper. Take a large book and place it on top of the eggs so that they support the book corners and raises it off the counter or table. You will see the eggs do not break and support the weight of the book. Now add another one on top of the last book. Each time you add a book record if anything is happening with the eggs. Gently keep adding books to determine how much weight the eggs can support. When you find the breaking point remove the books that were support and weigh them to determine how much weight the eggs could handle. This is really incredible.

Be ready with paper towels as this science project will require cleaning up from broken eggs. You may want to do the project next to a sink in the kitchen or an area that does not have carpet so clean up is easy.

Physical Science Fair Projects Made Fun and Easy

Physical science fair projects are for those who are interested in learning about electricity, energy, gravity, machines, magnets and how materials change and combine. There are many sub-categories that go along with physical science, so you should have no trouble finding a topic that interests you.

One interesting project is to build your own electroscope, which is really quite simple. The experiment involves taking a glass jar and covering it with a piece of cardboard that is a little bigger than the jar’s opening, sticking a nail into the middle of the cardboard, and then attaching two thin pieces of foil to the end of the nail. Another fun project is to create sparks with static electricity and experiment to find out what sort of materials work best for creating sparks by walking around on carpet and dragging your feet. This will work up some static electricity, which will allow you to create sparks when touching various materials. You can also further the experiment by seeing which type of shoes work best for creating static electricity.

Remember, when you are experimenting with sparks to use extra caution as sparks CAN result in fire, and make sure you don’t touch your computer when you are charged with static electricity, as you can damage the sensitive components inside. Also be careful not to touch any electrical appliances, although most are safely grounded. You could also experiment with static cling. See when static cling occurs, which types of materials are more prone to static cling and how you can stop it.
