Scientific Method

The experimenter changes the independent variable.

The dependent variable changes as a result.

an educated guess based on observations

Maybe.
Any lubricant that doesn't react with the surface coating will work between the blocks. Dry lubricants (soaps, graphite, waxes...etc.) or wet lubricants (oil, glycerine, water, soaps...etc.) work well to varying degrees depending on the materials they lubricate and whether the lubricant and the surfaces react adversely under heat and pressure. Consulting a lubrication specialist, (most lubricant manufacturers consult with customers for the best match), for your best results. PTFE can breakdown under high pressure and high temperatures and usually is not great for high speed high temperature operations but works great at low speed and/or low pressure applications, and it does not react adversely with most materials.

yes there is ther are 3 categories metamorphic,sedimentary,and igneous

A delta forms at the point where a river meets the ocean. As river water flows into the ocean, the water slows and sand and silt particles are deposited. This forms the fan-shaped landmass under the water known as a delta.

Hooke's law was designed to determine the restoring force of a spring, given its spring constant and the displacement of the spring from its equilibrium position. The law is written as follows:

F = -kx;

in which "F" is the restoring force, "k" is the spring constant, and "x" is the spring's displacement.

Ask the Native American population about the smallpox virus. We would not want to bring along diseases (viral, fungal, bacterial, etc) that might be able to attack native life should we encounter it.

Also, it complicates the search for life if we introduce contamination--i.e. we send a probe to Mars, return some samples with complex organic molecules, and cannot determine whether it is life from Mars or contamination.

Is a conclusion about observations FROM an experiment?

yes...

The Karvonen method was founded by Finnish scientist Dr. M. J. Karvonen in 1957. The method deals with the heart rate reserve and the desired heart rate to burn calories.

There is no point in collecting data simply for the sake of collecting data. You need to analyse it: summarise it and use key information from it to make some assessments about the data.

None. It's not the color of the candle that determines how quickly it burns -- it's what the candle is made out of.

being able to duplicate the research

A hypothesis, or group of hypotheses, that is accepted as consistently valid is a theory. Either a hypothesis or a theory can be ultimately disproven. One definition of a theory is an accepted hypothesis.

No

The results of studying the hypothesis are not repeatable and are open to judgement. The hypothesis cannot be tested by controlled experiments.

Discard or change the hypothesis.

To find out if your experiment went as you as you predicted.

Because it's not scientific, its actually an very old legal principle.

It helps break down big numbers like this

Example:

3,000,000,000,000 equals 3 times 10 to the 12 power because there is 12 0s

a hypothesis is an educated guess of an observation about the world

Sure. But the magnifying glass can't squeeze any more heat out of your light source
than what the source has without the magnifying glass.

The only thing the magnifying glass does is take all of the light ... and maybe heat ? ...
that hits the magnifying glass and focus it down to a very small area. It has no more
heat or light to work with than what enters the glass.

The most efficient way to heat water with a light bulb is to shine the bulb straight up
and hang the pot over it.

A observation is statements that are determined by using your 5 sences

Copepods are a subclass of crustaceans called Copepoda in the class Maxillopoda. There are several orders, each with several genera, each with several species. Just to provide one example out of many species, there is a freshwater copepod found only in the US called Aglaodiaptomus kingsburyae. See http://www.answers.com/topic/copepoda-2?cat=technology

Science is useful everywhere. Having good knowledege is very importanat as it can benefit you when you need it. Like for example, you are lost in the forest and need food, shelter and water. You will know if you learned that if you are lost in the forest at dusk, the sun would be at the west. If your home is east you can go the opposite way. If you are lost at night , you can follow the north star. You might also need knowledge on poisonous fungi and plants and be alert of edible and inedible stuff.
