Fun Science Experiments
Fun science experiments can capture the attention of your children and help get them excited about learning. There are many fun science projects that you can do easily at home with your kids. This is one of the many fun science experiments that has been done in schools for years that can easily be done at home. Kids love this experiment because it is captivating and it yields an unexpected result. I recommend these fun science project kits as a fast, simple way to get started on your science experiment.
Under Pressure Egg Category: Physics To begin this experiment have your children peel the eggs and make sure they are completely clean of shells. Take one of the peeled eggs and place it on top of the opening of the jar. Make sure your children observe the fact that the egg sits atop the jar and does not move. Before proceeding with this experiment explain why the egg stays atop the jar. Tell your children that the balance between the air pushing up from inside the jar and the balance from the air pushing down on the egg is what keeps it in place. Gravity would have the egg push down, but the force from the air in the bottle pushes it up. Once you have explained why the egg stays in place remove the egg from atop the jar. Drop two lit matches into the jar and put the egg back on top of the jar. Have the children carefully observe all of this. The egg will eventually be “sucked” inside the jar. After the egg is “sucked” into the jar talk about what happened to the egg with the children. Explain that the egg was not actually sucked into the jar it was pushed. Explain that the matches in the jar changed the balance of pressure between the air in the jar and the air in the room. The air in the room actually pushed the egg into the jar. That is because the matches removed some of the air in the jar, so it was unable to push up with equal force to the air in the room.
