Edible model of DNA made of twizlers and marshmallows. Pro: Fun and easy way to help students understand the form of dna. Con: I feel that the pieces of dna would be eaten by the students before the model is made.:)

Free Biology Lab: Simple DNA (deoxyribonucleic acid) Extraction.  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.

You’ve probably learned or heard about DNA, but have you ever seen it? With the Strawberry DNA experiment, you’ll extract, isolate, and observe the DNA of a strawberry in a matter of minutes.

This sample life science curriculum has a nice activity on observing and classifying fingerprints.

With a focus on literacy and collaboration, this activity teaches students about the importance of enzymes, DNA sequencing, fingerprinting, mutations that can happen if we smoke and even what it means to be a twin. | by Scaffolded Math and Science

DNA crime scene investigation. Each group is given a long paper strip of DNA, a 3-page story of the missing necklace and directions on how to fingerprint and sequence their DNA. Scissors act as the restriction enzyme, cutting the DNA between every CCGG into varied length segments. As the segments are pasted into the corresponding rows on the sequencing board (imitating gel electrophoresis), the DNA fingerprint of each suspect will emerge. So, who stole the necklace?
