The Strongest Man in the World Can’t Break this Egg!

Do you think that you are pretty strong? Is your father or mother strong? When you think of eggs, you probably don’t think that they are really strong, do you? In fact, you probably think that they are pretty weak, because if you drop them, they always break and make a big mess.

This science fair project is easy for students in kindergarten and first grade to do. Usually, science fair projects want to prove that a hypothesis is right (or wrong). For younger students, this can be too difficult to do. Here is the question that you are going to answer in this project: can you break an egg by squeezing? Can your mother or father break an egg by squeezing it?

The process of this science fair project is pretty easy. The equipment is something that you have in every kitchen: eggs and a bowl. The first step is to inspect the eggs to check and see if there are any cracks in them. Eggs that are cracked should not be used. To see if you can squeeze an egg, place it in the palm of your hand and close your fingers around it. Then squeeze it as hard as you can (over the bowl, of course, so you don’t make a mess all over the kitchen). What happened? Were you able to squeeze the egg and break it?

Repeat the experiment asking people who are stronger than you (and who have bigger hands) to give it a try. Could they squeeze the egg and break it?

If you are doing the experiment right, you shouldn’t be able to squeeze the egg and have it break. The reason why is that unlike what we believe, eggs are really quite strong. When thinking about how a chicken lays an egg, you can see that they are squeezed a lot, but don’t break.

Taking the same eggs that you tried to squeeze, break it (over the bowl). How did you do it? You probably tapped it against something, making a crack in the egg, and then were able to break the egg.

The structure of the egg makes it very strong, and unless you break the structure, even the strongest man in the world (or the person with the biggest hands) can’t squeeze an egg enough to make it break.

So was your answer to the question on whether or not you would be able to squeeze an egg right? Since you have been playing with eggs, you should make sure to wash your hands with soap and water to prevent some of the bacteria and viruses that can be found in uncooked eggs. After that, you may want to ask your mother or father to cook omelets for dinner.

A Fun Science Experiment - Layers Of Liquid

Apart from doing science fair projects, simply doing science experiments for the fun is a good idea as well. There are so many elementary science fair projects to do, kids can have lots of fun without ever getting bored, especially homeschoolers must make an effort to do as many fun and easy science experiments to instill a love of science in the kids.

Our fun experiment today will show how different layers of liquid can be formed in a jar because of the difference in density of the liquids.

If your water is too dark you cannot see the layers properly. Make the water light.


What you will need for your science experiment:

• A glass half filled with water
• 4 tablespoons of vegetable oil
• 4tablespoon of golden syrup
• Food coloring
• A clean glass jar
  

How to do your science experiment:

1. Color the water in the glass with a little food coloring. Do not make it too dark or you will not be able to distinguish the layers very well. Your layers will also not stay very long as the water with the food coloring will start coloring the syrup as it dissolves in the water. (It practically “soaks up” the colored water, do you know why?)
2. In a clean glass your spoon four tablespoons of vegetable oil
3. Slowly add four tablespoons of the colored water to the jar.
4. What happens?
5. Now you add the four tablespoons of golden syrup to the jar very carefully and watch what happens.
6. What do you think will happen if you add the liquids in a different order?
7. Why do you see three layers?
8. Why is the syrup at the bottom and the oil on the top?

Wind Erosion Science Fair Project

Wind erosion is another major problem in many parts of the world and it is good to see how bad it is in your vicinity.
For a good science fair project you have to make sure you use the correct scientific method. In a good ebook such as 24 Hour Science Projects you will be able to read all about it.

So, on to our little science e project:

This is what you will need:

• A few stirring paddles that you will get from a paint store
• Some broad double sided tape
• A felt marker
• A camera for your photos
• A note book and a pencil for your notes
  

This is what you have to do:

1. Stick the double sided tape onto the paddles (as many as you wish to use)
2. Now you stick the paddles into the ground in various places close to your home, ask an adult to go with you for safety’s sake, mark each one clearly and write it down in your note book.
3. Make sure the paddles face in different directions such as north, south, east, west, northwest and so on.
4. Now check on these paddles at regular intervals, say about twice a week.
5. Record what you see on the paddles and take photos.
6. Make sure you make a not of the location of each paddle
   

This project will show you how much wind erosion is in your vicinity by the amount of dust and dirt that are collected on the puddles. Write down exactly what happens and why you think there is a difference in the different paddles. What lies in the vicinity from where the wind came? Did that have any influence on the amount of dirt on the paddles? Does the wind blow mainly from one direction where you stay? Do you think that can have an influence on your project?

Science Project – More About Pollution – Polluting A Pond Or Lake

Image: FreeDigitalPhotos.net

When you go camping you may think it is fine to wash your clothes and dishes in a pond or lake, but is it the case? Are you polluting it or not? Detergent is supposed to clean, so what does it do to a pond or a lake? For all the info on how to do a good science project as well as examples of projects you can do in 24 hours or less go to: 24 Hour Science projects.

So, to start this science project, formulate your hypothesis. Is the detergent in the lake or pond polluting the water in the pond? Will it have any negative effect on the life on and inside the pond?

What you need for this Science Project:

• A plastic bag
• A large bowl of water
• Liquid detergent
• Wax paper
• Fastener or staples
• A camera for your photos
  

How to do this Science Project:

1. Stuff the plastic bag with the wax paper.
2. Close the bag with the fastener or the staples
3. For fun draw a duck on it to represent one of the species on the lake or pond
4. Let your “duck” float on the water in the bowl
5. Now you add a little detergent to the bowl of water
6. What happens?
7. Do you know why it happens?
8. What is the reason a duck stays afloat and dry in the water?
9. What changed when you added the detergent to the water?
10. So, do you think it is a good idea to wash dishes and clothes in a pond or lake?
    

Explanation:

Just as the oil on a ducks feathers the plastic and wax paper is water repellent, which means the water does not stick to it.
The detergent though, enables the water to stick to greasy materials. This then allows the water to cling to your plastic “duck” and a real ducks feathers making it impossible for the duck to stay dry and afloat.
