This lesson is one I use to make the standard DNA extraction lab (common in any biology class), into a lab that has actual variables to examine (usually this lab qualifies as more of a demonstration instead of an inquiry based examination of DNA). In this lab students examine a critical question, conduct research, create the hypothesis, collect and analyze data and use that to draw a conclusion. The packet is 5 pages consisting of guidance for all aspects of the experiment. Students answer questions, collect data on a data table then conduct math calculations and graph their results, on on the pages provided. After that there is a section of analysis questions as well. This assignment fits very well with state biology standards related to DNA structure and technology.
