This is one of my favorite labs/activities that I do with my Biology I students. It doesn’t take long to do, it uses very simple, household materials, and it works every time! There is no number crunching or data analysis, but just a fun activity that your students will really enjoy.
Students will use ordinary substances such as Dawn dishwasher detergent and alcohol to extract the DNA from cells. My version of this lab uses wheat germ as the organism from which the DNA will be extracted.
This is appropriate for grades 6 and above.
