Science Experiments

It is used to raise the temperature of the water.

A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.

By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.

Mechanical energy is the sum of kinetic energy and potential energy of some object. So any object in motion, has potential to be in motion, or has both has mechanical energy.

Your car in motion has kinetic energy and potential for more kinetic energy in the gasoline that it runs on. So your car has mechanical energy. Or you up on the three-meter diving board at the pool have potential for kinetic energy when you take a swan dive off that board. You have mechanical energy there.

But, bottom line, pretty much any object that is either in motion or can be put into motion has a form of mechanical energy.

This is an example of physical equilibrium, because if you look at the two phases (physical property) of water at zero degrees C, they both exist. At 0ºC, the molecules of water go back and forth between being a liquid and a solid, thus the equilibrium.

So you do not get any harmful chemicals in your eyes that could make you blind. Also to protect your eyes from other dangers that creep in the lab.

Zebra's that live in the Plains of Africa are on an average about 50-52 inches (1.3 meters) tall at their shoulder. Their body length is approximately between 6 to 8.5 feet (2 to 2.6 m) with a tail that is an additional 18 inches in length. Zebras can weigh upto 770 pounds (350 kgs) or more. Males are usually slightly bigger & heavier than females.

Items like H2O and CoC2 have a definite chemical composition, and require exact amount of particles to forma reaction. However; particles which are soluble in water do not have a definite chemical reaction.

If it is simply on tornadoes in general I would recommend something such as "Tornadoes: The Most Violent Storms on Earth"

It would be different if the project focuses on some particular aspect of tornadoes.

Primarily water passes through the stem of a vascular plant. However, minerals from the soil, which are absorbed by the plant's roots, also travel through the stem.

The simple answer is potential or stored energy. More complexely, chemical energy- energy is stored within bonds holding together mollecules of protein, fats, and sugars. Actually, sugars are the primary source of energy for living beings, which convert glucose mollecules (C6H12O6) and oxygen into H2O, CO2, and mollecules called ATP or adenosine triphosphate which are used to perform many tasks in the body. this is called glycolysis.

prediction. :)

Yes, fructose is considered a pure substance. It is a simple sugar (monosaccharide) that can be found naturally in fruits and honey. It is a single type of molecule with a specific chemical structure, making it a pure substance.

Both terms are sometimes used interchangeably, but "hypothesis" is more specific. It refers to a certain kind of prediction that is based on extensive research. Usually, a hypothesis will also need to explain itself. After experiments have been conducted, the hypothesis will either be supported or not supported by the results. A prediction does not necessarily require the research and support that a hypothesis needs.

well idk a good sciene project maybe egg in a bottle you can ask or Google that if you like!

It takes alot of effort and hard work and alot of commitement to make a science fair project. It also takes alot of time to do it and you must use your time wisely.

But the most important thing of all is:you have to believe in yourself and believe that you CAn do it just as long as you set your mind to it!!!!!!!!!!!!

Good Luck,Ariana Navarro

Google doesn't do any thing exspecially if it is to tomarrow.

The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas

This is a partial statement of Newton's first law of motion, which states that a body at rest will remain at rest and a body in motion will remain in motion at constant velocity in a straight line unless acted upon by an outside force.

Lava will cool quickly compared to underground magma.

There is a relationship between the power of an objective lens and its field of view. As the power of the objective lens increases, the size of its field of view decreases

Malleable materials are pliable and capable of being hammered out of shape without cracking or breaking. Some examples include: gold, aluminum, lead, nickel, copper and iron.

Depends on the concrete

An empirical equation is

4500*sqrt(R)

where R is the nominal compression resistance (usually 30 MPa)

R needs to be expressed in MPa in this equation

Mendel became famous for his study of the pea plant. Gregor Mendel's study of this plant led to significant contributions in the field of genetics and heredity. He is called the" father of modern genetics." Mendel was born in 1822 and died in 1884.

Redi showed the need to limit/control outside variables when he covered 1/2 the jars and got different results than the uncovered.
