This resource is a quick, easy and affordable lab that with a small amount of prep work beforehand, can be completed in 15 minutes with students (not including post lab questions).
Includes pre- and post-lab questions asking students to observe and explain the DNA extraction process. Also includes teacher notes and answer key.
The lab report is a 2 page (1 page printed duplex) sheet that walks students through the list of materials being used and has clear, methodical steps to complete the lab in an efficient and thorough manner. The 3rd page of the resource lists the answers to the post lab questions as well as my notes for the teacher.
Materials per group of 2-3 students:
10 mL of Extraction buffer (water+salt+soap) in test tube
10 mL of Ethanol or rubbing alcohol in test tube
½ of a Strawberry
Plastic sandwich bag
I included a Word version for easy editing as well as a pdf version.
Note: this resource is in a zip file. Some computers may need a program such as Winzip to open these types of compression files. Please see this website for more information on how to open a zip file here.
