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 difference between Bounty and Publix paper towels?

Bounty because it has two layers of paper towel publix has only one layer so bounty obsorbs more liquid than the publix natural brand

Why is it necessary to use careful and systematic methods when carrying out scientific investigations?

The scientific method requires carefully controlled environments and closely monitored methods because the experiment must be able to be repeated with similar results by others.

What is prior hypothesis bias?

People tend to like the first idea they hear and are hesitant to hear other ideas that clash with the first idea.

How is adding a ammeter to a circuit different from adding a light bulb?

When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.

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.

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.

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.

Is one of the most effective ways to evaluate data is to try to replicate it?

One of the most effective ways to evaluate data is to try to replicate it. This also gives you the option of saving your data on different locations.

Is the scientific method based on conductive reasoning?

in solving scientific problems, a method of reasoning is used which begins in the generalization and is called as
