One of the most amazing aspects of physics is the electromagnetic spectrum—radio waves, microwaves, infrared light, visible light, ultraviolet light, x rays, and gamma rays—as well as the relationship between the spectrum and electromagnetic force. The applications of the electromagnetic spectrum in daily life begin the moment a person wakes up in the morning and "sees the light." Yet visible light, the only familiar part of the spectrum prior to the eighteenth and nineteenth centuries, is also its narrowest region. Since the beginning of the twentieth century, uses for other bands in the electromagnetic spectrum have proliferated. At the low-frequency end are radio, short-wave radio, and television signals, as well as the microwaves used in cooking. Higher-frequency waves, all of which can be generally described as light, provide the means for looking deep into the universe—and deep into the human body. Among the most familiar parts of the electromagnetic spectrum, in modern life at least, is radio. In most schematic representations of the spectrum, radio waves are shown either at the left end or the bottom, as an indication of the fact that these are the electromagnetic waves with the lowest frequencies, the longest wavelengths, and the smallest levels of photon energy. Included in this broad sub-spectrum, with frequencies up to about 10 7 Hertz, are long-wave radio, short-wave radio, and microwaves. The areas of communication affected are many: broadcast radio, television, mobile phones, radar—and even highly specific forms of technology such as baby monitors.

Though the work of Maxwell and Hertz was foundational to the harnessing of radio waves for human use, the practical use of radio had its beginnings with Marconi. During the 1890s, he made the first radio transmissions, and, by the end of the century, he had succeeded in transmitting telegraph messages across the Atlantic Ocean—a feat which earned him the Nobel Prize for physics in 1909.

Marconi's spark transmitters could send only coded messages, and due to the broad, long-wave length signals used, only a few stations could broadcast at the same time. The development of the electron tube in the early years of the twentieth century, however, made it possible to transmit narrower signals on stable frequencies. This, in turn, enabled the development of technology for sending speech and music over the airwaves.

Physical Science Projects. 8th grade. PLEASEE HELP?

If I had a dollar for every time this question is asked ...

As references, I've listed a wealth of sites with a wealth of project ideas. Thanks to Former MN Science Teacher for many of them. Check out the past winners/entrants at the scisvc.org site for more difficult projects. If you find better references, please tell me.

Be creative. Don't waste this extremely valuable experience by copying someone else's idea. Focus on what interests you. Choose the best and most interesting project that you're confident you can accomplish in the time allowed. And allow plenty of time. A really good science project looks very good to college admissions officers, especially if the fair judges agree and award you a prize. You want to show that you can think, reason, manage a project, do proper experiments, write your results clearly and accurately, and that you're willing to work. Do your own research. Do your own work. Get help and get advice. Teachers and people in industry are often very willing to give advice and to make equipment and facilities available to someone who really cares about their project. It's a great experience.

(YA limits me to 10 links, so I split them between the answer and the references.)

Physical Science HELP!!?

When you have a confusing word problem try to take the distractions out (such as where they are and what they're riding) and see what they're really asking. The keywords are mechanical energy, kinetic energy, and potential energy.

Mechanical energy, the capacity to do work, is the sum of kinetic and potential energy. You have a mass already in motion (kinetic energy), and you will be adding more kinetic energy in the future (potential energy) thanks to gravitational acceleration. After that gravitational acceleration has been picked up the system is all kinetic energy. So... If the cart were to splat on the pavement instead of rolling away on the track, the total energy that would have to dissipate at once is what? (i.e. 72600 + 35280 = ?)

Put an egg in vinegar (this is really cool!) what do you think will happen?

Put chicken bones in various sodas, which dissolves the quickest?

do an experiment on the water quality in your area. Test for pH and total dissolved solids (buy test strips, most of this can be gotten from a hardware store). This is really interesting, and is usually a winner.

candy chromatography. you can usually get professional chromatography equipment for cheap, and easily too. you can also do it on the different types of gatorade.

You can test for radon gas in the area. Again: test kits

You can test different things for radioactivity. You'll need a geiger counter (you can buy or make one, its easy again...) Test people smoking, its quite high.

Advantage is power availability. But usually that is done by a power company, not a town. How is the town planning on connecting this power plant into the power distribution system?

Disadvantages are cost, pollution, and noise.

Recommendation: they have no plan on how to distribute the power, so they should talk to their local power company. Let the power company absorb the cost.

Science project: help!?

Physical science is the study of physics and chemistry of our natural surroundings.

Now, since there are 4 categories, I will assume you need pictures of three different objects from each category. This is what I would suggest:

Physics:
- A colorful paint or flower (how we perceive wavelengths of visible light)
- A moss-covered stone (an object in motion stays in motion, an object at rest stays at rest)
- A waterfall, falling leaf, or something falling (the idea of gravity)

Chemistry:
- Something burning (difference between spontaneous and non-spontaneous reactions in regards to their chemistry terms)
- The curved-top of water in a glass or a water droplet (bond-interactions)
- Rub a plastic comb with some felt and place it next to a stream of water from a faucet. The water will bend (electron/charge interaction)

Earth Science:
- A smooth rock (erosion)
- Clouds (the water cycle)
- A map (plate tectonics)

Astronomy:
- The moon (how it interacts with the earth, tides, gravity, and so on)
- A sun dial (how the path of the sun shows time of day)
- Stars (how their shapes/locations are used for navigation)

Drill bits are made of Tungsten Steel which is an alloy meaning it's made from more than one metal. Tungsten is very prevalent but shaping it into a drill bit is expensive because it has to be done in a vacuum. The handles of power tool are usually plastic because plastic does not conduct electricity well and therefore is an insulator as opposed to being a good conductor or electricity.

Need help with 5th grade physical science project?

go with a topic count u already understand a lot approximately so the study isn't as severe, or go with some thing u are rather attracted to, that way, you will learn from it and bring an impressive attempt. Me in my opinion, i might do the human physique and sexual reproduction, omg you have got everyones interest besides as u probs understand a lot approximately it already, and if u dont, u quickly will

Project title:
camote leaves extract as an alternative coloring materials
Difficulty level: High school
Main link: None

Hypothesis:
1. there is no significant difference on the effectiveness of the coloring material based on the application to different types of paper.


Materials:

1. camote leaves extract
2. crushed white candles
3. cornstarch
4. cheesecloth
5. mortar and pestle
6. beaker
7. vegetable oil


The Procedure:

Collection and Preparation

The camote leaves were gathered early in the morningto preserve its freshness. Before extraction, it was washed in a tap water to remove unwanted insects and particles. Then it was strained to remove the excess water. The extraction process begins.

Production of Coloring Material

The extract was obtained by pounding the leaves with mortar and pestle and strained with a cheesecloth. In a 100g of camote leaves, the extract only reached 50ml in a 600ml beaker. The extract was mixed with 100mg of crushed white candle and three drops of vegetable oil. After mixing, the extract was heated to dissolve the candle and stirred thoroughly until the colored solution was mixed with the wax. After the wax turned green, unmixed color were separated by a cornstarch. Cornstarch absorbs water content on the extract. The colored wax was poured on the molder.


Results:

The result shows that the effectiveness of the product produced depend on the thickness of the paper. the thicker the paper, the more visible is the color and the thinner the paper, the lighter is the color and vice-versa.
The color produced was only color-green.
