Science Experiments

nature is far beyond the logical capacity of man. there is infact natural explanation, which is evolution of mass, water, air and its combination to make further complex substances. what is seen is striving of life and reproduction, which is natures way of multilying and substracting.

An experiment is performed to generate more data. If the data proves to not support the hypothesis the experiment was still useful. You could reproduce your experiment to see if it is performing the way it should. After you have confirmed the experiment is performing correctly you then could devise another experiment to further test your hypothesis or accept the result and revise your hypothesis.

1. Beliefs. A scientist believes that everything that happens in this world has a cause or reason.
2. Curiosity. A scientist shows interest and pays particular attentions to objects or events. He asks questions and seeks answers.
3. Objectivity. A scientist is objective if he does not allow his feelings and biases to influence his recording of observations, interpretation of data, and formulation of conclusions.
4. Critical-mindedness. A scientist bases suggestions and conclusions on evidences. When in doubt, he questions the veracity of a statement in relation to the evidences presented.
5. Open-mindedness. A scientist listens to and respects the ideas of others. He accepts criticism and changes his mind if reliable evidence contrdicts his believes.
6. Inventiveness. A scientist can generate new and original ideas.
7. Risk-taking. A scientist expresses his opinions and tries new ideas even at the risk of failure or criticism.
8. Intellectual honesty. A scientist gives a truthful report of observations. He does not withhold important information just to please himself or others.
9. Humility. A scientist is humble when he admits that he is not free from commiting errors. He recognizes that there may be better ideas and realizes that there are individuals whom he may have to consult to arrive at correct observations and conclusions.
10. Responsibility. A scientist actively participates in a task and also dutifully performs tasks assigned to him.

The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)

Bread can develop fungi if it is not stored properly or if it is exposed to moisture. Fungi spores are present in the environment and can land on bread, leading to mold growth. It is important to store bread in a cool, dry place and consume it before it goes bad to prevent fungal growth.

As a rocket descends, gravity is pulling it down whilst drag is stopping the gravity having some of its power because without the drag the rocket would be pulled down to the ground within a matter of seconds.

I don't know how it affects it on its ascent!!

Sorry!!

It's only an experiment if 2 or more conditions are compared. Lava in a cup is a science observation or demonstration.

To make it an experiment, you would have to compare 2 conditions, for example lava cups with salt vs. lava cups with baking soda while keeping all other variables constant.

warmer temperatures will cause the milk to sour faster because the enzymes that cause the protein breakdown into amino acids (hence the sourness) have an optimum temperature at which they work and this is usually just above body temperature. That is why milk is stored in the fridge.

The answer is : watts

physical change is reversible because you can undo it for example: if you fold a paper you unfold the paper.

chemical chang is irreversible because if you make somthing together you could not seperate them.

The rectangular glass plate you are referring to is likely a microscope slide. Microscope slides are commonly used in laboratories to hold samples for viewing under a microscope. They provide a flat and transparent surface that allows light to pass through the sample for observation.

In an experiment, the condition manipulated by a biologist is known as the independent variable. The condition that changes based upon how the independent variable was manipulated is known as the dependent variable.

While is SOUNDS impossible, yes. you can- under the right circumstances. It requiress an exact balance between an even source of heat, and the wetting of the bag. Heat keeps the paper from getting too mushy, water keeps the paper from catching fire. This has been used for years as a Boy Scout camping entertainment. Not suggested that you try it indoors- parts of the bag above the waterline catch fire, and sometimes the bag comes apart.

Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results

Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.

No, Neptune is a gas giant composed primarily of hydrogen and helium with no solid surface. Its atmosphere is mainly hydrogen, helium, and methane, with no known vegetation able to survive in such extreme conditions.

Genetics, Age of culture, type of growth medium, and technique used could result in a gram-variable reaction

August Weismann disproved, or attempt to disprove the theory of Lamarckism (which states that: the adaptive trait gained by an organism during its life time can transfer to the new generation of organism; in contrast, proponents of this theory states: changes to genes can only be done through natural selection, and the experiences of changes to an organism's genes during its life time does not transfer), by cutting off the tails of mice, for many generations to observe changes to their traits. However, after many generations, no changes to the tail lengths of mice were observed. Thus, with this experiment and many that followed it, most considered Lamarckism to be disproved. However, during recent years, Lamarckism has garnered considerable interests, as observations have shown that Lamarckism does exist. For example, the epidemics of the population whose previous generation has experienced starvation is more likely to produce children, who, for generations, is likely to have genes with higher risk of high blood pressure.

The blue stain is called crystal violet. It can color the bacteria a blue color only if the cell wall is very thick. We then call that bacteria a Gram+ bacteria. Knowing the Gram test (+ or-) and the shape of the bacteria, we have a quick idea of what it might be. Then what antibiotic could be given gives a head start on a treatment. This can take as little as a few minutes. Further tests are usually done later on. They can take 24 to 36 hours to get a result.

The kite was invented by the Chinese; Ben Franklin used the kite instead of using conductive rods to avoid danger. Ben strung up a key to the kite and the string used on the kite is kept dry to act as an insulator so that Ben will be less electrocuted while standing on the ground.

You multiply by 1 million, i.e. 1,000,000. This is because milli means 10^-3 of a metre and nano means 10^-9 of a metre. 10^-3/10^-9 gives 1,000,000.

Salt water does cool faster than pure water.
