Thanksgiving Forensics CSI DNA Extraction & Fingerprinting Gel Electrophoresis

Who stole Mr. Gobbles, the famous Thanksgiving parade turkey? Students will extract DNA from strawberries to learn about DNA extraction. Then, they will run paper "DNA" evidence through a simulated gel electrophoresis chamber to make a DNA fingerprint. Your students will love this Thanksgiving-themed, engaging FUN FORENSICS activity! Feathered Fiasco is a comprehensive classroom resource designed to introduce middle school and high school students to the exciting world of forensic science and DNA analysis. This activity aligns with Next Generation Science Standards (NGSS) and is perfect for integrating STEM into your Thanksgiving-themed lessons.

The Story:

In the peaceful town of Gobbler's Grove, the beloved turkey Mr. Gobbles, famous for his extraordinary feathers, was the pride of the annual Thanksgiving parade. But this year, just before the festivities, Mr. Gobbles disappeared!

Activity 1: DNA Extraction of a Strawberry:

Students will use a simple technique with easy-to-find materials to extract DNA from fresh strawberries.

Activity 2: Gel Electrophoresis Simulation:

In this part of the activity, students will be given five paper strands that represent DNA. The first strand is from the victim’s (Mr. Gobbles) feathers. The other four strands were collected from the suspects. Their job is to color each strand of DNA and then cut the strands with scissors at the same location a restriction enzyme would make a cut. They will arrange the fragments in order of size, from smallest to largest on an image representing an electrophoresis gel. Then they will compare the cut pieces of DNA from Mr. Gobbles' feathers to the pieces from the suspects to see if they can find a match.

*Activities 1 and 2 can be used separately as stand-alone activities or together for an extended activity.
