Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

What is the purpose of using the scientific method?

to make careful observations

(got this off a study guide at school haha)

What is a description of the sequence scientific method?

The sequence of the scientific method moves in this way: Purpose > Research > Hypothesis > Experimentation > Analysis > Conclusion

What is an example of Discovery Science?

Jane Goodall's study of wild chimpanzees is a example of discovery science

What skills are needed to use the scientific method?

1) A little knowledge in your area of interest, and the resources to get more knowledge as you need it; 2) A great deal of curiosity. Then, it's a matter of getting the hang of thinking in terms of dependent and independent variables, and how you are going to set up your investigation. Just GO with it; mistakes and wrong turns are part of the process (within reason... you don't want to spend time and fortunes attempting to prove that the earth is a globe...)

Substances that dissolve in water?

substances that dissolve in water include, sugar, salt and others.

Can a scientific law have an exception?

No. No exceptions whatsoever. Otherwise, it wouldn't be a Law.

Which of the contributions to the latent period depends on the position of the stimulating electrode?

The position of the stimulating electrode is what contributes to the latent period. The further away the stimulus is from the Central Nervous System, the longer the latent period will be.

What is a priori prediction?

a prediction about outcome that is predited. Such as weather forecast

How does a punett square work?

A Punnet square has 2 parts on the left and 2 parts on the top. It is used to help make sure you don't forget any parts of combinations.

The parts on the sides are combined to make a two part thing in the midde.

For example a xx and a xy can combine in the squares to make two xx and two xy squares.

Why does data have to be reliable and accurate?

most of the time you would want it to be accurate and reliable but sometimes it doesn't it.depends on what the subject is

Why micro-emulsions are milky in appearance while macro-emulsions are transparent?

Emulsions tend to have a cloudy appearance because the many phase interfaces scatter light as it passes through the emulsion. Emulsions appear white when all light is scattered equally. If the emulsion is dilute enough, higher-frequency and low-wavelength light will be scattered more, and the emulsion will appear bluer - this is called the "Tyndall effect". If the emulsion is concentrated enough, the color will be distorted toward comparatively longer wavelengths, and will appear more yellow. This phenomenon is easily observable when comparing skimmed milk, which contains little fat, to cream, which contains a much higher concentration of milk fat. Two special classes of emulsions - microemulsions and nanoemulsions, with droplet sizes below 100 nm - appear translucent.This property is due to the fact that light waves are scattered by the droplets only if their sizes exceed about one-quarter of the wavelength of the incident light. Since the visible spectrum of light is composed of wavelengths between 390 and 750 nanometers (nm), if the droplet sizes in the emulsion are below about 100 nm, the light can penetrate through the emulsion without being scattered.

What is the formula for TMA and AMA?

AMA=force produced/force applied

TMA=distance effort moves/distance load moves
