Science Experiments

The results of the memory test

A scientific theory begins as no more than a hypothesis about an issue. Scientific laws are hypotheses that have been proven. Proving an hypothesis involves the ability to accurately predict the outcome of reactions. Unproved scientific theories can be regarded as highly as a law if they have not been disproved over a lengthy period of time, when the means to adequately prove the theory are unavailable.

When north sea gas is leaking a terrible smell arises and so, you should not put any lights or anything got to do with electricity on.

If a researcher fails to control the relevant variables in an experiment, you could end up changing a bunch of different variables in an experiment, and you wouldn't be able to tell which variable is responsible for the results of the experiment.

Idk.. I dont Know.. Sorry Im a Blonde Who Loves Cute Guys.. and im a total Fool.. for Green and Blue Eyes (: If your Blonde 'Gringo' lol(: Answer this question.. (;

Bye.. Babee

if any factor in an experiment changes, you have a brand new experiment. -A factor in an experiment that can change is known as a variable.

conclusion

Constant : these refers to values which do not change. they have the same value throughout the process. Like "1" is a constant value it will never change 1 will always remain 1. i.e.1=1

Varaibles= these refers to those quantities or values which change.for eg. if in a mathematical equation we have "X" variable. Now "X" can have number of values X =2 or X= 3 or X=10000 so they are called variables because their values change.

LEAD ABSORBS MICROWAVES
Sorry, but lead really doesn't effectively absorb microwaves - it is primarily reflective with only a trivial amount of "absorption". The term "absorption isn't quite quite correct - it really should be "attenuation" i.e. the microwaves are attenuated - lose their energy which can then be converted to heat - as they penetrate into a material. In that sense, water is a good microwave absorber, as are moist foods generally.In a broad sense, all materials are either primarily reflectors of the microwaves - such as aluminum; transparent to them - such as glass, paper or many plastics at lower temperatures; absorbers or attenuators - such as water, tea, moist foods, polar solvents such as nitrobenzene. However, all materials will exhibit all three properties but to a different extent - aluminum primarily reflects microwaves, but they do penetrate to a very tiny amount referred to as the skin-depth and so can caused a trivial amount of heat.

water, air, sunlight, nutrients such as nitrogen phosphorus and potash and several others

It would be 0.99996 g/ml and to 4 sig. figs. that would be1.000 g/ml

In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome.

The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.

Considering that everything else is equal, ie. glass, incoming wire. If you are talking only about the filament wire that is attached between the Two poles inside the bulb, the answer is friction.

The thicker the wire the less resistance it will have and will allow more electricity to pass without creating friction, the friction is what causes the wire to heat up and glow.

cuz the earth is awesome! but we r all gunna die soon so it does not matter k bye

Words that work are frost, hoar-frost, or rime.

There are many characteristic of a best rock in building buildings. For easy work you can use marble, limestone or dolomite. For durability and strength you can use igneous rocks such as basalt.

they tend to vibrate

As a general rule of thumb for most substances as the temperature increases the density decreases. There are a few well-known exceptions to the rule; for example the density of liquid water between 0 degrees and four degrees Celsius actually increases with temperature to a maximum at 4 degrees (after which it starts decreasing again). Even more widely known is that liquid water at 0 degrees Celsius is more dense than ice at the same temperature; this is very unusual, as for most substances the solid phase is more dense than the liquid phase.

Sand is heavier than salt

That's why sand bags are used, rather than salt bags.

Trur

you could see what kind of wood burns faster

or which color flame burns hotter or last longer( like not going out over a period of time)

this is an experiment that only one varible is manipulated at a time

independent variable

dawn has the most dish soap bubbles...hope i helped u
