Country Crafts and QuiltingCause Joy

wire coat hangers are used for a variety of crafts and experiments, but for this experiment a plastic hanger will suffice. If you have already a transition to plastic hangers for their children, then it is a great exercise that will not damage a hanger and encourage good fascination with science. Following these instructions, a classroom or just one parent and the child may touch on the basic principles of sound production while using a little creativity.

Library materials may be fun for children, or can be collected in advance (If time and number of children). You will need a clean, strong rubber bands, glue, a plastic hanger, wire, and a dozen pieces of dry cereal like Captain Crunch or Cocoa Puffs Puff. If your children have a favorite cereal, we use and the activity can also serve as an appetizer.

Take the wire and cut a dozen pieces about twelve inches long. If your children are cut, is a good idea to have a piece already cut for them to compare with, instead of having to measure each room. After all the wire is cut, glue the pieces of cereal to one end of each piece. You can try to tie the pieces, but can be difficult, depending on the type of grain. Connected parties may also take the most unequal length of wire, and experience works best with the same length. Then you plug the other end of the pieces of the bar at the bottom of the hanger. Once all have been related parties hang the hook on a stable object like a chair, closet rod, or a table. Drag the different pieces of floss up and down the bracket grains so that the pieces are suspended in the same distance from each other. The closer the better, but it should still be a bit of space between each one. cereals Give a few minutes to hang freely so that it becomes immobile, and ready to spring to gain experience.

The elastic band should be held between the teeth and stretched with one hand. A child can then pull the rubber band with the other hand, like a bass. It is important not to bite the rubber band hard or stretch the elastic too. This can be done instead of an adult or a child can hold the elastic stretched, while the other bracket. Experience continues to operate without the aid of the teeth, but the vibration is higher due to the solid surface of the tooth. Continue to pull the rubber near the training center hot cereal.

While the rubber band is plucked, it vibrates. This can be seen in the rubber, but as you continue pieces of grain are also beginning to move. As the nearest piece of grain is moving much closer to the other parties begin to well. None of these touch things, and not force it can be seen, but the vibration of the rubber band is at the origin of the grain to move. Elastic vibration that produces sound waves in the air, affecting hot cereal. All the sounds they make these invisible vibrations traveling through air, liquid or solid and reach our eardrums. Like the pieces of cereal, our eardrum and the small hairs inside our ears also move by vibration. Our brain computes the speed and strength of the vibrations help us understand what is the source of vibration, and so perceive the sound.

The sounds are created by our brain, we mean the kind of vibrations that reach our ears. The world is full of complex vibrations of all types create many amazing sounds we hear every day, and this little experience with a hanger help children to understand more about where the sound is really.
