so scientist can compare result
In an experiment, the constants are the things that are the same (or don't change) for the control group and the experimental group. For example: You want to see what the difference is of washing your dishes in the washing machine for 20 minutes and washing them in the washing machine machine for 30 minutes is, a constant would be to use the same kind of soap. Basically make sure that everything is the same for both groups besides the independent variable, or you will have an unintended variable.
There are multiple trials conducted, and the procedure for collecting data is properly designed.
It is important to use the same amount of water each time you conduct the experiment because if you change more than 1 thing in an experiment, then you can't know the true result because you tested too many things. You need all controlled variables in an experiment except for 1 manipulated variable.
use of factorial experiment instead of single factor experiments
You would use a hypothesis during an experiment. The experiment does not necessarily have to be of science, though the term hypothesis is primarily used for such category.wordnet.princeton.edu/perl/webwn defines hypothesisas# a proposal intended to explain certain facts or observations # guess: a message expressing an opinion based on incomplete evidence A hypothesis is seen in the beginning of an experiment, stating a prediction by the one(s) conducting and carrying out the experiment. The rest of the experiment, or procedure with data, then serves to prove the hypothesis a true and possible prediction, or to be incorrect. The outcome of the experiment is what determines if the stated hypothesis is a successful and true proposal.The hypothesis's success or failure is recorded in the conclusion section of the experiment, located reasonably at the end.-youFITCH.

A constant is something that will ALWAYS remain the same in your experiment. For instance, the materials you use and the unit of measurements you use are examples of constants. An independent variable changes with the experiments.

to store values
The scientific process. 1. Observe 2. Create a hypothesis to explain what you observed 3. Experiment to test your hypothesis
Mathematical analysis is tremendously important for understanding the result of an experiment.
so the solution will not be contaminated or changed during the reaction
You can quote something from your primary source and use footnotes.
Whenever possible, a hypothesis should be tested by an experiment in which only one variable is changed at a time. All other variables should be kept untouched and unchanged. Scientists use the data from a controlled experiment to explain the steps and outcomes that produced their final product.
Let's do another experiment!
