Bias
A concave lens is called a diverging lens because it causes light rays to spread out or diverge as they pass through it. This results in the rays appearing to come from a virtual focal point behind the lens, opposite to the direction of incident light.
Liquid is often measured in a tall glass cylinder that has a graduated scale etched on its surface.
Forces that come in pairs are called action-reaction pairs. This is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
The device used for heating objects in science is called a heat source. This can come in the form of a Bunsen burner, hot plate, or an oven, depending on the specific experiment or process being carried out. Heating objects is often necessary to initiate chemical reactions or change the physical properties of a substance.
Gases change to liquids when their kinetic energy decreases, causing the atoms or molecules to come closer together and form intermolecular forces. This usually happens when the gas is cooled down or its pressure is increased.
Data obtained from an experiment is the results you got from whatever test or experiment you did. Data obtained for a research paper is the information you got from your research. Basically, it is the data/info/results/etc you need to come to a certain conclusion.
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
This is called scientific method. First; you start off with a question, and then you try to guess an answer to your question with a hypothesis, then you run an experiment and analyze the results and come to a conclusion.
After the experiment, the next step in the scientific method is to analyze the data collected from the experiment. This involves organizing and interpreting the results to draw conclusions about the hypothesis.
Yes. The order is question, hypothesis, lab, organize data, communicate results
If observations don't match the theory, then either the theory or the experiment is wrong. Maybe a measuring device isn't sensitive or accurate enough. If the experiment is right, but results doesn't match theory, then it's time to come up with a new theoru that matches the experiment's results.
The more scientists that conduct the same experiment, with the same results, the more the findings can be trusted. Also, more scientists are more likely to come up with variances or solutions due to different ways of thinking and approaching things.
Before conducting an experiment, a math problem or series of calculations one usually writes down what their expectations are that a certain result will come from the calculations or experiments. This is called a Hypothesis. You then conduct the experiment or set of calculations, in order to find out whether your expectations, based on your estimations, were correct, or wrong.
To make your hypothesis considered scientific it must have testable and measurable results. Example: If you do an experiment and the results are testable and measurable another person would be able to do the exact same project and come out with the same results.

Trial and error is when someone tries something and it doesn't work (the error) so they try again (a new trial) and again until they get the experiment right or get the results they want.Scientists usually think through all possible options, to minimize error. If the results don't come up even with any way of checking, then they know something is wrong. It is highly unlikely, and usually doesn't happen. The more important the experiment, the more time the scientist will spend calculating, and recalculating the possible ways the experiment can occur, or have problems.
No, a result is something that happens because of something else. A conclusion is a desicion that you come to.
