referred to in the last twenty years, because of my work, I often make presentations on bicycle safety for all audiences bulls children. When I give talks to children, usually in a school assembly, I usually break into three parts. This first part is the introduction where I quiz the audience to see what they know and to correct misunderstandings. I must explain that the helmet and gloves will last line of defense against accidents.Knowledge and skills are the main lines of defense. When I grow up I mean to recommend a course of study available on DVD as "Bicycling Over Balance" If the truck does not want, but the children, I recommend you still find a course, give them the information, an idea which skills are necessary and how to teach those skills. The second part is a presentation on helmets and the third part is a video age appropriate. These three parts are usually about forty45 minutes. The focus of this article is the demonstration of the helmet.
Lead to demonstration
When in front of an audience for my presentation to make bicycle helmets, is the first thing I ask the public for a show of hands from people who think you need a helmet for bicycling. My hand up. You do not need a helmet for bicycling, should be avoided. The first line of defense in injury preventionexperts in safe driving techniques and the ability to implement them.
Explain how a brain is injured
Without groped to explain what I mean to frighten the public brain injury. I declare that there is no need to open the head and brain injuries which often leads to cerebral contusion small crack in the brain. A "simple" You can prevent them from being damaged by tasting your favorite food or reunification. The fact that most adults surprisesSever bump on the head today can cause epilepsy later in life. I would also tell the story of my wife's hairdresser. He borrowed a bicycle from a friend and was on the sidewalk, and for some reason he fell and hit his head ride. A blood clot in his head the size of a grapefruit removed and had to relearn how things that we all take for granted such as speaking and cutlery will. to the point of this story is not to scare people into the helmet to show the usual excuseI do not go on the road or I do not go near the car. You can drop a bike at any time and do not need to be in collision with a car a necessity. At this point I want to see what happens to the head in the fall and impact.
After a brief statement that the brain is supported by the spine and which is surrounded by cerebrospinal fluid, I ask the audience to imagine that the helmet I think it's a skull, my clenched fist of the brain and my arm spineColumn. I declare my heart in the helmet and that if a person is moving the skull and brain as one and if the head to strike anywhere matches or a little more protected the brain from some of the liquid and all should be good. When I explain this center, I prefer a helmet with a fist down. I then explained that if the head of the platform there is a sudden stop, but the brain is floating in fluid motion, until he meets the interior of the resultsSkull, and if you can blow your mind, the brain inside the skull more than once taken. I should note that, like ripples in a pond to beat the cerebrospinal fluid in the skull in order to produce the brain and can cause more damage in the brain.
Egg Drop Demonstration
Now you have passed some of the details of brain damage and the public to understand how brain injury occurs, and I know how easily the brain caninjured. I wear a helmet demonstration. I used to use a helmet and a melon, melon like about the same size and weight as the plane I thought this would be a realistic demonstration, but between the cost of melon and replace helmets, cracked, it had expensive. Now I use the eggs.
There are two parts to the demonstration. Part one issued to a head and secured the second part of the head unprotected prove. You will need theSupplies listed below.
Medical Supplies
1. Three of them (not boiled)
2. 1 box of styrofoam packing peanuts or sand (clean and free of stones or sticks)
3. Newspapers
4. Sharpie marker (optional)
5. A table with a hard surface (optional)
Part One: The protection circuit
The physical setup is easy. Put newspaper on the floor and the fieldpeanut or packing sand paper. Make sure the paper extends below the field enough to keep the floor clean egg case lose if you drop the field.
This part requires a little audience participation. They show the public the egg to ensure there are no cracks. Centrifuge to show the egg, not hard-boiled, if she falters with gloves. You can look in the box to show them that you are not trying to deceive them by hiding the egg of a secondin the field. If you ask the audience is children, with the egg. To draw a face as he shouts the egg. With the drawn face and your egg called, keep the egg on his chest and asking the audience if you break the fall of the eggs in the carton that is. You then lay the eggs higher and higher until you can not go higher before dropping the egg in the sand. I usually try one or two feet above the audience thinks that breaks increase. Iare standing on a chair at the edge of the stage and let the egg feet ten or eleven feet high. From experience I can tell you that this will drastically increase your chances of missing the box or hit the board and gives you great opportunity for some theatrics on the field is the lack of an egg and injected.
Once you drop the egg, the members of the public may crack. If the egg is broken, it will be used again for the second part ofdemonstration. If the egg has some small cracks on one side and put a fresh egg to the next part.
Part Two: The head is not protected
For this, remove the box and leave the paper on the floor or a table if you put the card on the table and use it for demonstration. This makes it easier for the public to see the decline. Hold the egg over his head and ask if you want to break the egg on the table or the floor to drop. Youcontinue to ask this question of how to cut closer to the hard surface. If you are about six inches above the ground, the answers are conflicting. Keep lowering the egg can fall to about 4-5 inches and then. The egg will crack. sometimes bruising or may even split apart. Again, ask the public to inspect the damaged egg. Compare the contents of the box wearing a bicycle helmet. The sand or styrofoam heads the energy from the drop-while the sand and the foam helmet. If you compare the first egg cracked on the way in which the sand or egg from polystyrene, it was easy as the other egg lightly protected by only four inches of damage.
At this point, it is inevitably a question, why not wear a helmet for adults. The only answer I can give me is that sometimes adults do not make the best decisions.
