Scientific Method

Break it down into a sequence of simpler problems, each of which may be broken down further until the problems are simple enough to be easily resolved. Each simple solution should be implemented as a simple function with just one or two very simple statements. Breaking problems down in this way makes code easier to read, especially when each function's name closely reflects the purpose of the function (rendering code self-documenting). Once you have a working solution, you may find some of the simple functions can also be used to solve other complex problems, thus reducing the need to write duplicate code.

The purpose of a Science laboratory is to carry out small experiments ( trials) and see whether an experiment is successful.If this expt is successful in the Lab then one can use this expt on a bulk scale for any purposes like manufacturing of a product, or research a product or carry out practically anything or replicate the lab Process.

It's an inference because your drawing a conclusion (that the cat must be ill)so it is inferrence

.,.,.the SCIENTIFIC METHOD usually begins in OBSERVATION w/c leads the formulation by HYPOTHESIS that can be tested by EXPERIMENTATION, and then you may now list/analyze the DATA after that the last is to GENERALIZATION.,.,

To be truly testable, a hypothesis should be falsifiable, with counter-testing and proof of the null hypothesis possible.

First you have to find a problem then find a question or what you are going to test. An example would be paper towels, such as how much weight they can hold. A hypothesis would be, "Bounty will hold over two hundred pennies. A hypothesis is an educated guess.

Rock salt is mined as a solid in salt mines. it does not need to be separated.

A. Hassam watches people as they interact.

The moon orbits Earth because it is held there by Earth's gravity. The moon is going fast enough that it won't hit Earth, but at the same time is being pulled back in at the same rate it flies away. The same is true for why Earth itself doesn't fly into the sun.

the sun is MUCH MUCH MUCH further away than the earth is, so it is attracted to earth because the difference in size and gravity favour the earth. If it was to be attracted to the sun, the sun would need to be bigger or closer (both of which it is doing at aconstant rate, but very gradually over a long perios of time)

a thermos limits heat transfer through the walls of the thermos. that lets the fluid inside the thermos keeps its temperature nearly constant for a long period of time (whether the temperature is hot or cold).

The Maxwell Bridge is known as an AC bridge. This bridge is used to find the self inductance and the whole amount of a circuit.

When a hypothesis is not supported by data, two possibilities exist. The hypothesis can either be rejected and a new one is formulated, or more data is required to retest the hypothesis.

A1 Because water is a solvent, and as long as the material, in this case salt, has less density than the liquid itself, it should sink. But, other solutes like sugar, are denser and water, and will simply sink.

A2 Strictly, there are many many salts, and common table salt, NaCl is the one we meet most commonly. This dissolves readily in water as you remark.

Copper Sulphate 'bluestone' is another salt. Some salts are essentially insoluble, such as many of the Mercury salts - especially the Mercurous ones.

It depends on the metal but often it will change phase and crystal form and have different properties. As an example steel when molten is in what is called the austenitic phase. This is a face Centered Cubic crystal structure. When quickly quenched it becomes martensitic which is brittle and Body Centered Tetragonal. Cooling down slowly will produce a pearlite structure.

If a liquid metal is poured into a mold it will take the shape of that mold and when cooled will keep the shape of that very mold. It will also contract/shrink.

insoluble

The only way to 'place' water on a hot burner is when it is a solid (ice), or as a container of liquid water

Naturally, the hot burner would melt it into a liquid and rapidly boid it away into water vapor (gas)

A hypothesis is tested in a scientific investigation.

it depends upon the amount and the shape of the ice.

capable of being proven false.

testable

Anything heavier than water sinks; anything lighter than water floats.

Or, another way to say it: anything with a higher density than water (water weighs about a gram per cubic centimeter), or a higher specific gravity than water, sinks.

If the object weighs less than the weight of water that it displaces, then it floats.

Rules make it possible to understand the world.

Flagellates have flagella, which are tails, that help them move. A flagellum is a bundled microtubule tail that propels them through liquid.
