If you did the experiment wrong
Fist the scientist figures out the aim of their experiment. Then they make a prediction. And then they make a theory before actually doing their experiment. After the experiment they make a conclusion and then evaluate their experiment (what went wrong, how things could be better...). Hope this helped! :)
This depends on the specific experiment desired.
You use a formula to make an experiment.
to make the experiment more reliable
Make a sentence using hypothesis, controlled experiment and variable. Make a sentence using hypothesis, controlled experiment and variable.
To make an experiment valid you have to make sure that the experiments results answer the question that you first started from.
redo or retest the experiment
Repeat the experiment and make sure it is fair.
performing the experiment multiple times
To make an experiment more accurate you would have to repeat the experiment 3-5 more times to make it reliable and also you would do what Liverpool college do and compare the answers with other people in the class, community or teacher.
a solution example is ... you will be doing a experiment and you would try to make a solution work to make the experiment successful
