Tools can range from instrument of measurement like thermocouple, equipment like test tube or even a hammer for geologist, complex construction like the hardron collider to the use of knowledge like matrix operation as tools for mathematician. Tools can be invented per task of study,it is unlikely number of tools can be countable.

Though its rigorous 'rules' regarding what falls under good science, read 'science with integrity.' Namely, this is through a strong sense of empiricism via a focus on provable claims, repeatable tests, and a strong peer review system.

'Provable claims' disallows a science based on mythology, allowing only 'scientific' type ideas to enter the realm of 'good science' (this is hard to fully pin down as there may be many instances of good science that did not start with provable claims, none the less, it is considered important to have such).

'Repeatable tests' and 'peer review' ensures science is not built on false data. First, the scientist repeats their experiments until the data is strongly conclusive. Second, they send their data off to be reviewed by experts who will do their best to poke holes in it.

It is by this way that science moves from claim to test to review to theory in such a way that 'bad' science rarely finds a foothold.

it is a physical change , sublimation is a transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. the iodine crystals when subject to heat turns to a violet gas , and when it cools it turns back to solid form. the composition doesn't change so it n is only a physical change

Among other things, it must be based on reliable data and repeatable experimental results.

In a chemical reaction, the starting materials are called the reactants.

It is a conjecture, or an hypothesis in the scientific method.

An hypothesis supported by experiment can become a theory.

No, the scientific method can be uncontrolled to for it to be valid.

The steps in the scientific method are: 1. The scientist asks a question. 2. The scientist develops a hypothesis (an educated guess). 3. The scientist tests the hypothesis. 4. The scientist determines whether the hypothesis is correct. 5. The scientist records the steps, so that others can repeat them to see if they obtain the same results. In my opinion, the most important step is the first. We would not be able to make any new discoveries, without someone asking a question.

Because the saltwater is dehydrating it, just like it will dehydrate humans eventually.

A freshwater paramecium would shrivel in salt water due to a precess called osmosis.

Osmosis is a type of diffusion that occurs in water. If you have a container with two different salt concentrations separated by a fine screen (semipermeable barrier) that will allow water to move back and forth, but not salt, the water will try to move to the side with more salt to dilute that salt. This is what happens to your paramecium. The water inside the paramecium will move outside the paramecium to try to dilute the saltwater, causing the paramecium to shrivel like a ball that has had the air let out.

Further explanation of osmosis can be found at http://en.wikipedia.org/wiki/Osmosis

As a side note, this is why drinking salt water actually dehydrates a person. When you have salt water in your digestive track the water in your body will move into your digestive track to dilute the salt water. The water is then excreted through your urine leaving you with less water in your body then before you drank the saltwater.

We are long past the hypothesis stage, with regard to electricity, which is a very well understood phenomenon at this point. If you would like to know about the history of scientific investigation of electricity, there were a number of hypotheses, including the hypothesis that lightning is a form of electricity (which is true) and that nerve impulses are also a form of electricity (also true) and that electricity can be generated by some types of chemical reactions (also true) and that electricity can be used to make the Frankenstein monster come to life (not true).

This important step in the scientific method is called experimentation.

• scientist analyes their experiment

In the history of science this approach was not originally used. The Ancient Greeks believed in doing observations and arriving at hypotheses and theories (both Greek words). They however did not believe in doing experiments.

Geologist must use their knowledge of the events that disturb or remove rock-layer sequences to help piece together the history of Earth as told by the rock record.

Observation is the process of gathering objective data, and inference is the process of making some decisions about what the data...

Let me start first of all by saying that hypothesis are guesses that scientists make,so they need to be tested because they are just mere guesses from one of the scientific processes of observation.so guesses need to be confirmed by testing to see how true it is,therefore since hypothesis are guesses scientists make,then it needs to be tested

Scientist used abstract reasoning to explain how something happened.

A qualitative test will reveal a person's chance of having a virus. Usually, the results only detect a small chance of a person getting sick.

The independent variable is how each jar is covered.

The dependent variable is the amount of maggots in each jar.

The control groups are Jar1( no covering, left open), and Jar 2 (covered with netting).

The experimental group is Jar 3 Sealed from the outside).
