To give final result to our observation
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
all it is is the uncontrolled experiment is a little bit different
They need to keep a record of each step, then start the experiment over and try not to make the mistake again or make changes in what they did to see what outcome they get.
they need to know so they can record their results accuratley and get a result that is reliable.
You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.

we need to identify the precautions method in performing an experiment inside the laboratory to determine do's and don'ts and to make our experiment satisfied. Knowing the laboratory set-up is important so that we can perform our experiments easy and enjoyable.
If it is the same experiment attached to link, you would need only 1 trial each unless you want to retry if there is more grain or shape distribution. There is no requirement for how many time in repeating experiment since it is observation experiment not measuring experiment.
You have different kinds of methods for doing the a simple experiment in science. You need a prediction materials Observation Procedure and hypothesis for the experiment you do. 1st you make a prediction gather all the materials for your experiment and you start follow the experiment and last but not the least you have to check your hypothesis and prove it.........

"Experimenting is the best way to get scientific information. Experiments are valuable only when closely and accurately observed."
The conclusion is the goal of performing the experiment, without it the written results of the experiment would only be a "jumble of data". Other scientists need the conclusion both to validate the experimenter's reasoning and to decide on future experimental directions to take.
i think what you wear in the day depends on thats day weather but on scientific perspective you dont need it, for in you dont need observation, hypothesis,experiment,conclusion and theory to dress for the day.
