Scientific Method

Many people recommend using a simple format.

- If... then...because... &

- include manipulating variable and a controlled variable of some sort Example: IF I put two clover plants into 3" pots and water one with soda and then other with water, THEN the one with soda will not grow taller BECAUSE of the sugar content in the soda.

A five letter word for a scientists mistake is "error."

Hurricane categories are determined by a storm's maximum 1-minute sustained wind speed.

Category 1: 75-95 mph

Category 2: 96-110 mph

Category 3: 111-129 mph

Category 4: 130-156 mph

Category 5: 157 mph or greater.

There is no Category 6.

Determining your options means, by inference, that you will make decisions based on the information you gather. Note that even if you decide to do nothing, it is still a decision.

A valid hypothesis is one that is testable and rejectable, can be proven true as well as verified without external evidence. It also needs to be accepted by public opinion.

i believe you mean that the question is to do with the gradient of a line

the gradient of a line is the change in height divided by the change in distance

which is the same as slope divided by distortion

if a man goes up a hill and his height cahnges by 1 metres vertically and he walks horizontally 10 metres then the slope is 1 metre and the distortion is 10 metres.

Gradiend is 1 -10th or 10%.....

The Condemnations of 1210 to 1277 allowed scientists to pursue science empirically.

With the beginnings of the university system, standards on education were introduced to Europe. This happened in the 11th and 12th centuries.

In the 12th century, texts of ancient and medieval scientific words were translated into Latin and made available. These included both ancient Greek texts and Arabic. For whatever reason, the universities and their professors decided that they were going to teach strict conformance to Aristotelian science.

The implications of strict Aristotelian science included a halt to scientific advancement beyond what Aristotle knew, and that Aristotle was infallible. The second of these was found unacceptable by the Church, which began investigating into what to do about the situation.

The Condemnations of 1210 to 1277 condemned the teaching that Aristotle was infallible. This freed scientists to go beyond Aristotle. There are historians who believe this was the beginning of modern science.

your reason for choosing it

it made his actual results approach the results predicted by probability.

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.
