What were the observations that lead to Lowell's hypothesis and experiments used to confirm there were canals on mars?

There aren't canals on Mars, so I don't know what you're talking about when you mention experiments to "confirm" them.
Giovanni Schiaparelli (thought he) saw dark bands on Mars and called them canali, which in Italian means "channels" (as in river channels). That was mistranslated into English as "canals", a related word, but one which implies that they were artificially constructed.
It turns out they weren't anything at all. The telescopes of the time weren't good enough to permit seeing much of anything on Mars (it's bigger than the Moon, but it's also MUCH further away), and Schiaparellis' canali turned out, once we got better pictures of Mars, to be optical illusions.
Even at the time, not all astronomers agreed that the canaliactually existed, and even those that did generally drew maps different greatly in detail from those drawn by Schiaparelli.. E.E. Barnard (after whom "Barnard's Star" is named didn't see them at all, and other researches performed experiments designed to show how, given poor seeing conditions, random dark spots could appear to link up and form lines.

How do scientists know about things they cannot see?
In part, by observing the effects of things they cannot see directly (like the way quarks turn into subatomic particles, which cause detectable changes); or by using observations to confirm what mathematical models have predicted should happen (such as when Stephen Hawking determined that black holes must give off energy; the phenomenon is now called Hawking radiation in his honor).
Is there a contradiction between science and religion?
Religion staes what it knows as the truth and sifts facts to confirm its position (discarding contradictory evidence). Science observes the real world and attempts to find the explanation by testing theories that eventually may explain the observations - there are no right or wrong choices on data validity.
How can you tell if diamonds are real in earrings?
Take your earrings to a local jeweler who can use a probe to confirm that the diamonds are real -- or not.
What is the best way to spot a fake diamond?
Diamonds conduct electricity and a diamond probe can confirm that the stone does not conduct electricity, so it is not a diamond.
How did scientists confirm that the sun has hydrogen and helium power?
from energy spectrum of the of the sun it normally done in laboratory even for finding the elements present.
How do you know the students in the above study are acting as scientist?
Students could be seen to be acting as scientist if they are following the scientific method - Make observations, postulate a hypothesis, and form and complete experiments or further observations to confirm or refute that hypothesis.
What did galileos observations confirm?
He made many experiments and observations in the field of physics in general.
Repeating observations or experiments to confirm prior conclusions?
replication
How is the validity of scientic theory tested?
Scientific Theory is tested by observations and experiments predicted by the theory. If the observations confirm the theory the theory is validated if not the theory is not validated. Experiments themselves need validation, often there are errors in the experiments or observations, e.g Michaelson and Morley Aether experiment and red shift observations.
What is a general rule being suggested after a series of observations that all point to the same thing?
This comes from the scientific method. A hypothesis is a rational explanation for an observed phenomena. When multiple researchers confirm the observations in agreement with the hypothesis, the explanation of the set of observations can be referred to as a theory.
What is the significant hypothesis?
The significant hypothesis is the one that you will be able to confirm.
What is testable hypothesis?
A testable hypothesis is a specific statement that proposes a relationship between variables or predicts an outcome that can be empirically tested through research or experimentation. It is formulated in a way that allows for observations or data to confirm or refute the hypothesis.
What do scientist do when experiments show their hypothesis is incorrect?
If an experiment does not confirm his hypothesis, the scientist should report this honestly. Even if the results confirmed the hypothesis, further testing should be done by him or others to gather more data.
What did Galileo confirm?
He made many experiments and observations in the field of physics in general.
What makes hypothesis testable?
A hypothesis is testable when we can determine experientially whether it is likely to be false or more likely to be true. That means we must be able to distinguish between it being true or false observationally. Thus, equally important to finding observations that confirm the hypothesis, we must be able to specify what it is we expect to see in the case that the hypothesis is false: the hypothesis must be falsifiable in order to be testable.It must be able to be proved right or wrong.
What do scientists do to confirm a hypothesis?
They make continuous tests and evaluations until the hypothesis becomes validated and certified.
Has scientific knowledge changed over time?
New experiments are performed or old experiments are repeated and confirmed or contridicted. From this expanded pool of experimental data, new or refined theories can be made, which then provide hypothesis for new experiments that will either confirm the new/refined theory or support the original theory. The process is then repeated and science marches onwards.
