Inventions in the field of science have always played a major role in the course of history. Today, it is very difficult to survive without the existence of computers, automobiles, telephones, satellite communications, and other innovative technological mediums. Many great minds started their inventions since their early times of learning, like schooling and graduation. Well, you or your child can be an inventor too, if the brain power is consumed just a little more than what is usually needed. Particularly, if you are still very young, say in the 6th grade or so; this is actually the period of learning. Keep the habit of stimulating your brain for every science activity you do, and chances are more of you outwitting others when you grow older.
6th Grade Invention Ideas
Such ideas for students in this grade provides them with a chance to do away with the routine curriculum for a while, and they begin to explore and reach beyond their limitations. There is no specific background, in which the inventions are supposed to be performed.
How to Make an Egg Float
A student can take an egg, some salt, and a quart of water, and can show why an egg sinks in water. Also, they can use the equation of density, which equals mass/volume, and can easily present the sinking of the egg. Keep a track of the amount of salt used, before it floated and after it sunk.
In modern times, students can use electricity or fossil fuels for creating a flying machine. Materials that are compatible with these sources should be collected by the student. Like using iron, steel, or plastic with electricity or fossil fuels might have an adverse effect, or may give positive results too. These trial and error ways would help them to develop the model appropriately. Devices like hang gliders and bicycle helicopters could be few examples of such ideas for sixth graders.
Humans' hearing capacity reduces at a certain age, and this is a natural process. To present a theory on sound, a student must develop an audio experiment, and make a volunteer sit in the center of a room. The room must be divided into several audio regions. Every region should have a person volunteering to create some kind of a noise. Then the blindfolded person should be asked to make out the direction of the noise accurately. Record all this data, and make graphical visualizations of this sound experiment. Draw two graphs, one of the accuracy of hearing (age on hearing capacity), and second of the overall accuracy of the noisemakers, w.r.t. each region (place of the human ear).
