A child may carry out basic experiments to understand gravity, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time.<ref name="Stohr-Hunt">{{Cite journal|last=Stohr-Hunt|last1=Stohr-Hunt|first1=Patricia|first=Patricia|date=1996|title=An Analysis of Frequency of Hands-on Experience and Science Achievement|journal=Journal of Research in Science Teaching|volume=33|doi=10.1002/(SICI)1098-2736(199601)33:1<101::AID-TEA6>3.0.CO;2-Z|DOI=10.1002/(SICI)1098-2736(199601)33:1<101::AID-TEA6>3.0.CO;2-Z}}</ref> Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the [[இயற்கை அறிவியல்|natural]] and [[சமூக அறிவியல்|human]] sciences.
