Science Experiments

A factor that can be changed in an experiment is called an independent variable.

Yes. It is an experiment in which some gases - assumed to have been present in Earth's atmosphere some billions of years ago - were subjected to electrical sparks. After some time, this resulted in certain organic molecules' appearing from the gases. For more details, you may want to read the Wikipedia article on this topic.

There is also an article on the duke education Cruising Chemistry site, which is very readable.

He put him inside a chamber to see the effects of his deceased body.

No, that isn't true at all. People research and find only information that supports their own position all the time. It is true that using research helps you to get accurate information rather than just guessing... but in order to have an unbiased result, the person doing the research has to be unbiased, and actually read all of the perspectives, and no matter which one he or she agrees with, present them all accurately along with any conclusions.

A solution is a special kind of mixture. So yes, a mixture of salt and water could be called a solution. All of the salt would need to dissolve, though ... if there's undissolved salt in there, it's not a solution.

The group is called the test group or test subjects.

Variables

All variables except one, the experimental variable, are kept constant in an experiment.

The body would wiegh more in air than in vaccum because as we know that there many particles in the air and so their weight whether less or more will be considered with it but in vaccum it's opposite.

What does it mean when a student data that was collected from an experimental supports their conclusion?Answer this question…

The Control Group

An interesting property of light called refraction just took place. When light enters the water, it can't move as fast and it has to slow down slightly. It's kind of like how if you are walking, you can walk at a normal speed but if you walk in water, you can't walk quite as fast.

If light from the image enters the water straight, then the image looks normal - which was what you originally did when the pencil was straight up and down. If the light enters the water at an angle, then the change in speed between the open air and water causes the light beam to bend away from its original path. When the pencil was at an angle, the image was at a bigger angle in the water than in the air and made the pencil look like it was bent.

5 + 5 actually (in science) does not always equal ten. This is because when 5ml of water is added to 5ml of ethanol, then the volume will decrease because the water molecules fit like puzzle pieces between the ethanol molecules. I did this experiment in science class and we found that when we added them together we actually got about 9.25ml, while all of the other groups also got around that much. I think that others should know this fascinating fact about science and stuff. Just one more random fact you've ought to know!

These are the experimental values.

There is no limit to the number of variables a formula can have.

To see if biological compounds could form spontaneously on early Earth

To see if simple molecules can combine spontaneously.

To find out how biological molecules could have first formed
