That projects your child comes great science fair, which is waiting for all year, and do not know what to do with your project. We offer some ideas, but it seems boring to him and exaggerated. He has already seen a volcano with lava and volcanic ash, the smells different test animals, and that the power of vision testing people. Does not repeat a project that has already been done. As both come with an idea together. You decide to take the old car parts and car parts all over the house, which is more likely in the yard or garage in the rear, and experiment with them.
An experiment you can do in the old auto parts and car parts experience the sounds they make when they come into contact with other objects. You can have a bumper of a car on a marble floor and hanging on a string directly above the defense. When the marble is in contact with the bumper to see what sound it makes. Then try a light object, like a trombone, to observe the different sounds that the clip of the form of marble and paper. The dense heavy object, it is more likely to sound deeper and stronger, lighter and probably will be a sweet sound. You can try this with auto parts and various found objects.
You can also see how rugged old car parts. You can try to dissolve a variety of metal found in the car, or rubber objects on the machine, but be careful not to burn and the smell of rubber can also be harmful to the lungs, so make sure you have the proper safety equipment. Or you can try to crush the different parts of the car, or bend, and how resistant they are still.
Another experiment you might want to try is the reliability of safety belts. Take an old belt buckle and unbuckle him, and to compare it with a belt of new seats to buckle and unbuckle. Do they both feel equally tight and durable, and you seem to be more sustainable than others? The best way to really test this is on a moving vehicle, as this is really going to test the car before they are put on the market, but you probably do not have access to such of equipment.
The science fair is a big problem so it’s no wonder that your son is looking forward to it all year. If you do science fair project, parts of old cars and car parts, this would be the original idea, that not too many young people to prepare. So most definitely attention of some of these experiments, burning and destroying some of the equipment can be dangerous and hazardous to health, so make sure it is done in the presence of an adult and with the right safety equipment.
