record in science terms means keeping track of reactions in an experiment to reinforce how to get the same reaction so there is a lot less effort needed in that particular experiment.
It depends, if you are doing an experiment on temperatures of water in nature, you will need it. If you are doing an experiment on how fast different species of turtles can walk, you don't.
If you wish to write an essay about a science experiment, you should describe the purpose of the experiment, and the way in which the experiment was performed, and the results of the experiment, and the conclusions that are drawn from those results. If you want to be fancy, you might also describe what further experiments may be needed to continue to explore the subject of the first experiment.
What equipment was needed for this experiment
The Bible isn't science and may or may not be true. Galileo needed to have to experiment with real science and find out if his theory was correct.
Goal/Aim- What are you aiming for?Hypothesis- The possible answer that you are trying to approve or disapprove.Equipment- Materials needed to do the experimentProcedure- The process of the experimentResults- The outcome of the experiment/what happened/was your hypothesis correct?Conclusion- Your concluding sentence
Control in science is something that can be used for comparison to determine the magnitude of an experimental effect. For example in a control group either nothing is done or a fake version of the experiment is performed to determine a "baseline". The results of the control experiment and the real experiment can be compared. This process helps eliminate the experimenter expectations effect, making the conclusions more objective. Note: controls are rarely needed outside the field of biology.
Depending on the size of your experiment, you can do it your self. If the project is small, like testing the strength of an egg, you can do it yourself, but if it's a survey or a bigger project that could take you a long time, you might want to bring on an extra person or two.......or three.
yes
as many as needed
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
Peer review does the same thing for science that the "inspected by #7" sticker does for your t-shirt: provides assurance that someone who knows what they're doing has double-checked it. In science, peer review typically works something like this:
