Science Experiments

Time is almost always the independent variable, which is to say that time depends on nothing. Such is the case with viscosity measurments. The volume that flows through a hole over a period of time means that volume is dependent on time. Plot time on the X axis and Volume on the Y.

when using mass spectrometry to look at what they had made after their experiments with carbon, the scientists saw that the two most abundant forms of carbon made were c60 and c70. C60 can be organised into a football shape made from pentagons and hexagons, and to increase the football shape's size while keeping it geometrically symmetrical you need 10 more carbon atoms, which would explain why there were both c60 and c70 molecules in large quantities. This was considered proof that it had to be the shape of a football, because otherwise there would not be c70 aswell.

I believe that this has to do with comparitive relative densities of a. the liquid under consideration b. the actual hydrometeor.

It depends of which science we are talking about. In mathematics, a series is an infinite sum of expressions of more or less similar form, for example: 1+x+x^2+x^3+...

or 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+...

The process of osmosis.

The parts of an experiment that stay the same.

It is not necassary to have a catchy title, however it helps as it makes your project stick in the judges' mind.

Ya yo

This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.

Think it's 'control', not really sure

evaporation; the water evaporated to the air

A science fair project about Dream analysis would be a good idea. You can tell why dreams occur, are they symbolic, what do they refer to, etc.

Pesticides

it means like what happened when you were testing your science fair project so for an example if you did how salty does the sea have to be for an egg to float on water you have to say what egg floated and how much it weighed

Gneiss is typically harder than granite due to its higher metamorphism. Gneiss is formed from rocks that have undergone intense pressure and heat, which results in a stronger and more resistant rock compared to granite, which forms from the cooling and solidification of magma.

He says on December 21, 2012. I don't believe it though. He doesn't really know; only God does.

It draws narrow tubes inside plant stems to get the water.

Tape's the strongest because it lasts the longest. :)

all you have to know is identify the problem, gather information,state a hypothesis,state a hypothesis, organize data, analyze the data,and write a conclusion if it supports the hypothesis or not

Erm, I think you mean test the hypothesis.

i think people these days are trying to cotrol the hydregen bonds because that may effect

used a qualitative colourimetric test for the detection of cholesterol

A diploid cell with an extra chromosome. Basically a diploid with an extra chromosome of one type, producing a chromosome number of the form 2n + l.

It look like a ball and it has a small ball inside

In general, it is an experiment that is run by different experimenters, using different-but-similar equipment, in a different locale, and perhaps a different-but-similar testing protocol.

i believe it is how long an experiment is going to take.

for example, the testing range of an experiment with plants may take around a few weeks to months.
