People like to compare the humain brain to a PC. This is not accurate because the brain is much more complex then people realize.

Brain

Some view the brain as an organ. It is Woody Allen’s second favorite organ. I see the brain as many organs.

The brain contains cerebrospinal fluid which is housed in ventricles.

In diseases these ventricles expand. In schizophrenia and in Alzheimer’s disease, this swelling is due to tissue loss.

The brain is extremely complex

The Brain in Diseases

Pathology has been seen in the brain in many diseases including Parkinson’s disease, Huntington’s chorea, Alzheimer’s disease, schizophrenia, mental retardation, etc. In multiple sclerosis demylination is seen. Amyotrophic lateral sclerosis is also called Lou Gherig’s disease.

Conclusions

Although the brain has been studied at a cellular level, much more research needs to be done.

The brain is a neuron jungle, but glia are also very important.

This is very controversial, but mental diseases are brain diseases. The brain is made from, repaired by, and fueled by the food that we eat. To ignore this is a mistake.

Every year your science class teacher would probably ask you to build something out of the principles being imparted in class. So your school comes up with an annual science project. The objective of science projects is to be able to clearly display the principles of a particular branch in this course. So you came up with an idea to build hovercraft models using the applications of physics.

Physics is a major branch of science with many interesting principles which students can apply for their science project. From engineering to simple daily occurrences, this is one of the favorite discussions in a science class. The hovercraft, although not commonly used in urban transportation means, is a perfect example. And so you’re off to a good start.

Identify the materials that you can use. Understanding how to build hovercraft vehicles is the same with any vessel of this type. To come up with one for your project is simply improvising the materials and bringing the applied science to its miniature version. As mentioned, the objective is to show the principles.

The basic things you will need are:

1. Platform - You can use a wooden disk about the size of a manhole cover. You want a science project that is portable and easy to carry. So keep the size handy. This is probably the biggest in your hovercraft project.

2. Any vacuum cleaner or leaf blower - You can use the vacuum cleaner to provide air flow into your platform. You may use any other gadget as long as you can put the air flow in reverse but this is the easiest to find. Your build hovercraft model must follow the air cushion system of the actual hovercraft.

3. A plastic sheet that is flexible - This will serve as your improvised skirt. The skirt is supposed to trap air below your platform. When doing so, it builds pressure and thus creates a cushion of air. Because of the plastic sheet’s elastic properties, it will only allow limited air to disperse out of its contained space.

4. Fasteners - Now you have almost everything you need to make your science project. What you need to do next is to have some fasteners such bolts and nuts to fasten them together.

5. A sketch or design of your science project hovercraft - To do this, you need to check on other hovercraft kits. Learn the principles. The components should be similar to the materials you have. For example, the fanning system in actual hovercrafts is represented by your leaf blower. The hovercraft hull is you platform disk and so on.

All these things above you will need for the project. Your hovercraft project should be able to carry a real person. Of course you can’t guarantee it could carry anyone who is heavier than you. Use your weight as a basis. That is why the platform is suggested to be the size of a manhole cover for this purpose. Last but not least, remember to always pay attention to you science teacher in class.
