Any GOOD SCIENCE FAIR PROJECT IDEAS?!?!?!?!?!?
I know this type of question doesn't get many answers, but anyone who crosses this and reads this, PLEASE suggest something, and make sure it isn't a dumb one... it has to be one that almost 90% of people wouldn't know what would happen. In other words, no volcanoes and junk with baking soda... or in other words, just don't, and i repeat DON'T, put plain old classics...
8th grade science question!! please help!!!?
Intensity (sound seems louder in closed, smaller-than-outside space) and volume (you turned it up). Pitch is unrelated to volume, as is amplitude (sound wave height) frequency (radio station is unchanged, as well) and wavelength(again, unrelated to volume, it's the distance between troughs in soundwaves).
What are some ideas for a computer science fair project?
Well, look at other science fair projects. You have things like the infamous volcano. What is it? How does it work? What's the point? Well, it's sure not a volcano, is it? It's a representation of the volcano. Yes, science is used here, specifically chemistry, to create an effect that resembles a volcano and lava flow, but it's not. So what's the point? Demonstration, education, and novelty. I think it might be interesting to simulate a positive and negative Turing test. What do I mean by this? A Turing test is basically a way of verifying a computer as indistinguishable from a human. The point and field of application is Artificial Intelligence. Imagine two computers side by side in the area given to you for your science fair project and a small explanation of a Turing test, maybe include a picture of your face if you want people to remember you were the person that did the project.You'd sit away from the project and . One is running a "dumb" program designed to appear to be a person at first, but quickly becomes apparent that it is a program and not intelligent. The second computer would be connected wirelessly to a device you would use to communicate back to a program that looks identical to the other program. The difference being that this program would obviously pass the Turing test, as you would be able to reply directly. Only reply to the people typing to you within the context of what they type. The computer only knows what is typed to it. Be sure to use proper grammar and punctuation as well. Something along those lines. You don't have to actually build something amazing in software that is demonstrable. Just demonstrate the concept of some problem or solution in Computer Science with profound implications.
What kind of tool do you use to measure volume?
Volume is the degree at which something is listened to or the amount of room a strong, fluid or gas inhabits.- With noise, its volume is the loudness of the sound.- With a container, its volume would certainly be its ability, or how much it could hold.Measuring the Volume of SoundThe showing tool is typically a meter calibrated to review the audio degree in decibels.The tool visualized above is called a pH meter. It is a scientific measuring device that determines the level of acidity of a liquid. Having the ability to use scientific measuring tools such as this is an essential science ability.You'll find a wide selection of Measuring Instruments at Penn Tool Co.
How did mozart change the world?
I have to write an essay about Mozart. The prompt is; Three positive changes Mozart made to the world. Im having trouble coming up with 3 positive changes. Any ideas??
Why do the minor chords sound sad and major chords happy? I've read everything there is to read on this subject, and there's still no answer.
Science has yet to come up with an actual conclusion for this question.What the evidence does point to though, is that it is a product of our culture. We perceive, in western harmony, a minor third to be sad because that is how it has been perceived for centuries. It has become engrained in our brains to be sad.However, if you listen to Hebrew music or Eastern European music, they use tons of minor intervals in their music. They have their own scales such as the Hebrew scale or the various Hungarian scales. Their music isn't sad though, a lot of Hungarian dances and folk music used minor scales.Other scales to look at are the flamenco scale, Japanese scales and Chinese scales...basically all world scales actually XD.In other places around the world, cultures are used to pentatonic scales which are vastly different from our western ideas of music. Pentatonic scales can have minor intervals or major or even augmented or diminished intervals yet their cultures perceive these as normal and with their own emotions attached to them.I haven't found any conclusive articles online where scientists have found an actual reason for these intervals sounding happy. Especially since other cultures can contradict the western idea of 'major' and 'minor'.
