Implementation of a good experiment

In accordance with some experiments that we often do both at the school and even at university level, we can set up several questions that should be considered in conducting an experiment. Practicum course at the university in the state of the system which does not always allow us to focus on the experiment.

Therefore, to conduct a good experiment needs to be seen a number of factors, among others

1. Repeating the experiment in the same circumstances
   With this road soon becomes obvious errors that arise due to miscalculation in the experiment and other oversight. Also with the repetition several times can be reduced due to effects such a random error in reaction time, for example in the use of a stopwatch
2. Repeat using other measuring devices
   If a meter is damaged or suspected of the situation is less precise, clear way to handle it is to replace these tools with other tools. In normal practice, if the experiment goes well, students do not have to think about this problem. But lab officials should check all equipment regularly
3. Doing a comparison with the equipment under other circumstances. If there is suspicion that a formula or theory is incompatible with the existing experimental results, may place the necessary changes
4. Comply with practical instructions in the use of tools
   Ie, before a device is used, its use should be studied first go through this guide so that the usage will be more effective and the existing experimental equipment can be prevented from the defects that we want and besides that can prevent us from dangers that might occur due to errors in using experimental tool
