Description
Introduce students to organic extraction techniques with this "stimulating" kit. Students take advantage of the solubility differentials in various solvents to extract and isolate caffeine from tea leaves. They then calculate percent recovery and extend their learning to a real-world application of caffeine extraction. This kit does not use toxic methylene chloride and requires two 55-min class periods to complete. Kit materials are sufficient for a class of 30 students working in 10 groups of 3.

Results from this lab are very inconsistent between groups, especially during the extraction steps in Part 2 with the NaOH. Only one group out of four had a discernible layer after adding the NaOH. In addition, the initial instructions of boiling 100 ml of water with the tea bags for 10 minutes is pretty much impossible without evaporating all the water and burning the tea bags.
