在〈數位實驗技巧指南〉是設計來幫助你準備你的化學課程的一系列影片(共有10部份)。每部份影片體提供詳盡的常見的實驗室技巧示範，且是一個有益的技巧與資訊。這些影片該用來當做補充，而不是取代你的實驗指南或是被設計用來閱讀用。事實上，如果你已經先讀過正確的背景資料後，你將會得到最大的益處。為了成為一個出色的實驗人員，你必須了解理論與技巧!如果你對你所看到的結果有所疑問，去問你的助教或指導者以確定你所看的。
The "Digital Lab Techniques Manual" is a series of ten videos designed to help you prepare for your chemistry laboratory class. Each video provides a detailed demonstration of a common laboratory technique, as well as helpful tips and information. These videos are meant to supplement, and not replace, your lab manual and assigned reading. In fact, you will most benefit from watching the videos if you have already read the appropriate background information. To be a great experimentalist, you must understand both theory and technique! If you have questions about what you see, make sure to ask your TA or your instructor.
注意事項:在5.301中，使用的影片為3、5、6、9和10。
Note: In 5.301, videos 3, 5, 6, 9, and 10 are used.
