~hope i helped!
What are the three tools that scientists use to do experiments?
It would depend on which particular branch of science.
In all branches of Science you are "standing on the shoulders of giants" as Newton put it. That is you have the advantage of all previous knowledge.
Your own intellect and curiosity is a further valuable tool, including the ability to question 'acknowledged wisdom'.
And of course, your apparatus, including the ability to design a novel apparatus which will address the specific hypothesis.
An electron microscope is used to study atoms, as well as sub-atomic particles, A balance, a tool used to find the mass of a specific object, and finally, the petri dish, which is used to grow bacteria and other microscopic organisms.
Do Middle adults use their life experiences to learn new information?
Yes, middle adults often leverage their life experiences to learn new information. They draw on accumulated knowledge, skills, and insights to interpret and integrate new experiences, which can enhance their understanding and retention of new concepts. This ability to connect past experiences with current learning can lead to deeper comprehension and practical application of new information. Additionally, their cognitive flexibility tends to improve as they age, further facilitating the learning process.
What type of scientist was Mary styles harris?
She was a biologist and a geneticist (scientist working with genes) scientist.
What is the dispeller of spontaneous generation?
That would be Louis Pasteur's demonstration showing that boiled broth that is not exposed to micro-organisms from the air does not spoil. If you would like more detail you might consider looking at Pasteur's wikipedia article.
Why do scientist have different views?
to explain to the people what they found out and that person only.
Scientist conduct multiple trials of their of their experiment because?
connections academy this is cheating this is your science test!
I took the same test
How and when did the maths origin?
The concept of counting numbers (the natural numbers) probably predates human beings because many animals can distinguish between small numbers.
Which term is defined as scientists comparing their results with others and checking for accuracy?
Peer review is the term defined as scientists comparing their results with others and checking for accuracy. This process involves other experts in the same field evaluating the quality and validity of a research study before it is published.
What grade does Sally Ride teach?
I don't know but I have to say that the girl/boy who wrote that you are wasting time on here is right I am doing a toastmasters assignment on Sally Ride when all the other kids are outside playing and having fun while I'm doing this paragraph and looking for answers for Sally Ride and I don't find anything and I am 10 yrs. old.
A 10 year old should not be wasting there time on this they should be exercising outside and running like other 10 year olds do I am with the other girl/boy so if you are 10 do not waste your time play with your friends!:)
P.S can I know your name the one who wrote that paragraph?
Why scientist use control groups?
Scientists use control groups so that they have something to compare or contrast their independent variable to. Without a control group, they wouldn't have anything to prove if their experiment had any important change. For example, a scientist is trying to prove that the bugs in his garden is affecting his flowers. His control group would be a set-up without the bugs. He would have another set-up WITH bugs. After some time, he would compare the two. If he didn't have a control group, how would he know that the bugs affected his flowers at all? Maybe the flowers were changing due to another factor, but how would you know?
How do scientists make theories?
Fist the scientist figures out the aim of their experiment. Then they make a prediction. And then they make a theory before actually doing their experiment. After the experiment they make a conclusion and then evaluate their experiment (what went wrong, how things could be better...). Hope this helped! :)
Does the work of scientists begin with testing a hypothesis?
In an experimental project you will begin with background research and then make a hypotheses, and you will test it with different variables to prove your hypotheses true/false.
Name famous scientist and what he or she did?
Albert Einstein is one of the famous scientists. He was a theoretical physicist that created the Theories of General and Special Relativity.
What was nikola teslas education?
Tesla began his education at home and later attended gymnasium in Carlstadt, Croatia excelling in his studies along the way. An early sign of his genius, he was able to perform integral calculus in his mind, prompting his teachers to think he was cheating. Then he moved along to attend the renowned Austrian Polytechnic School at Graz to study engineering.
What is a state that scientist will always observe under certain conditions?
the answer is scientific law.
What is the early life of Nikola Tesla?
Nikola Tesla was born on July 10, 1856 in Smiljan, Lika, which was then part of the Austo-Hungarian Empire, region of Croatia. His father, Milutin Tesla was a Serbian Orthodox Priest and his mother Djuka Mandic was an inventor in her own right of household appliances. Tesla studied at the Realschule, Karlstadt in 1873, the Polytechnic Institute in Graz, Austria and the University of Prague. At first, he intended to specialize in physics and mathematics, but soon he became fascinated with electricity. He began his career as an electrical engineer with a telephone company in Budapest in 1881. It was there, as Tesla was walking with a friend through the city park that the elusive solution to the rotating magnetic field flashed through his mind. With a stick, he drew a diagram in the sand explaining to his friend the principle of the induction motor. Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. While in Strassbourg in 1883, he privately built a prototype of the induction motor and ran it successfully. Unable to interest anyone in Europe in promoting this radical device, Tesla accepted an offer to work for Thomas Edison in New York. His childhood dream was to come to America to harness the power of Niagara Falls.
Where did nikola go after the fight with edision?
Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. So he said. Tesla worked for Thomas Alva Edison for 1 year At that time, the most important "inventor" in the world was named Thomas Alva Edison-the so-called wizard of Menlo Park.... Edison was credited with the invention of the DC dynamo and the electric light bulb . . . but the only thing he really invented was the ELECTRIC CHAIR!!
Despite the fact that Tesla worked closely with Westinghouse, he still retained his own laboratory, and was very happy when he was working there. He continued to make new discoveries, one of which was a lamp that fluoresced, and was actually a forerunner of today's fluorescent tubes. These hit the market some fifty years after Tesla's prototypes! He also investigated many other phenomena including X-rays and a vacuum tube or valve very similar to the Audion or triode valve pioneered by de Forest in 1907.
What are the invention of Luis ma Guerrero?
Luis ma Guerrero is a famous foreign scientist that has invented the tropical medicine, so that this will help people in tropical places to cure their sicks very easier.

Only in marketing. Had he achieved his goal , most of our homes would be powered with DC electricity, instead of AC electricity, according to many historians.
Improvement for all: The answer given above is completely wrong. Tesla was a master of AC current and found a way to transmit AC current without wires. If his arch-nemesis Edison had successfully done something other than nothing with DC current, we would be living in a DC current world. The fact that almost everything on earth runs on AC electricity is probably Tesla's greatest SUCCESS. The failure was his lack of forethought in presenting a FREE energy distribution system to money hungry corporate capitalists. They discovered that Tesla's work could put them (specifically JP Morgan) basically out of the energy business, as over the air energy can't be regulated or metered.
