Are predictions that can be tested?
In science, an educated guess about the cause of a natural phenomenon is called a hypothesis. It’s essential that hypotheses be testable and falsifiable, meaning they can be tested and different results will ensue depending on whether the hypothesis is true or false.
What part of the experiment does not change and is set up as a standard for study?
Constant Through It All A constant is something that does not change across all of the experimental groups. These are used to minimize the effects of components other than the independent variable.
Why are more trials better?
When we do experiments it’s a good idea to do multiple trials, that is, do the same experiment lots of times. When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random events. Multiple trials can be done at one time.
