GENIE Go Bananas!

This is a simple and very flexible laboratory activity which can take from 20 minutes to over an hour, depending on the age of the students; numbers and, how involved you want to make it. The laboratory session shows students how to extract DNA from bananas, using ingredients that can be found in the home, and basic laboratory equipment. This activity has even been run in Malawi using improvised equipment such as plastic drinks bottles for funnels and drinking straws for pipettes.

GENIE has done this laboratory practical session with different age ranges, varying from age 10 (year 6), to adults and it can easily be adapted to suit. All these different age groups have really enjoyed it and have also found it a fun and exciting learning experience.

This session fits in with Key Stages 3 and 4 of the National Curriculum for England (ages 11-14 and 14-16).

What this activity will demonstrate is:

  • That DNA is contained within all living things.
  • That DNA can be extracted from living things using simple household chemicals.
  • That living things contain large amounts of DNA.
