Science needs both ideas and facts to move forward. Scientists answer questions about the physical world by formulating hypotheses and designing experiments to test them. The data collected helps them to find out a fact or facts that help us understand our world.

Is a hypothesis a proven fact?
A hypothesis is the idea of what the conclusion will be of your experiment.
Why do experiments have to be repeatable?
Apex Experimental results are not reliable if they are not repeatable.
Why is it important to gather information before doing an experiment?
If the answer is already a well known scientific fact, it would be a waste of time to do an experiment. It also helps you know what additional items you may need to do an experiment.
Definition of experiment?
The definition of an experiment is a procedure that is done in order to make a discovery, test a hypothesis, or test a known fact. An experiment is often the testing of a scientific theory, although it can be applied to other fields as well, as long as it meets the criteria of the definition.
Is a hypothesis considered to be a fact?
A hypothesis is a proposition to be proven or disproven by experiment or, in the case of statistics, to be assessed for its likelihood based on the numbers available.
What is a fact about a hypothesis?
It is an educated guess before starting an experiment.
Is a hypothesis a proven fact?
A hypothesis is the idea of what the conclusion will be of your experiment.
Why do experiments have to be repeatable?
Apex Experimental results are not reliable if they are not repeatable.
What were the surprising results of Rutherfords experiment?
The most surprising fact about Rutherford's experiment is that some of the atoms bounced backwards while others scattered.

What were the surprising results of Rutherford's gold-foil experiment?
The most surprising fact about Rutherford's experiment is that some of the atoms bounced backwards while others scattered.
Which fact about gold could not be discovered in Rutherford's experiment?
There are a few things that are true about gold that could not be discovered in Rutherford's experiment. There are solid atoms in the region that are called Nucleus.
What does a conclusion mean in science?
It's usually a statement that shows that your aim of the experiment has been achieved and that you have justified a fact. This justified fact is the conclusion. For example; if the aim of your experiment is 'To study whether plants need sunlight to sustain life', your conclusion would most likely, and by in fact, be 'Plants need sunlight to sustain life.'
What does conclusion mean in a report?
It's usually a statement that shows that your aim of the experiment has been achieved and that you have justified a fact. This justified fact is the conclusion. For example; if the aim of your experiment is 'To study whether plants need sunlight to sustain life', your conclusion would most likely, and by in fact, be 'Plants need sunlight to sustain life.'
How do we know atoms are made up of small dense positive nucleus?
The first ever experiment this fact was the alpha particle experiment which was conducted by Rutherford. In this experiment, alpha particles are positive charged substances and they were repulsed with the nuclei in the golden foil.
Are mutually exclusive events independent?
Not necessarily. In fact, in binary situations they can be totally dependent - depends on the experiment.
Was Nikola Tesla involved in the Philadelphia experiment?
No. In fact, the Philadelphia Experiment is widely regarded as a hoax and details of the story contradict well-established facts about the Eldridge, the ship it allegedly occurred on.
