In Brief: First, students examine prokaryotic and Eukaryotic DNA, and compare/contrast them. Next, students read some background on DNA, genomes, chromsomes, prokaryotes, and eukaryotes, and answer some questions based on the reading. Then, students create models of bacterial and fruit fly chromosomes using string, paper, markers, and tape. Finally, they answer conclusions questions about their models.

: This activity gives students some basic background about the structure and function of DNA, and prokaryotes vs. eukaryotes. It is not necessary, but may help to have students know the basics about the structure of DNA in order to do the activity.

I put together a research and presentation project in which students choose a Genetically Modified Organism, create a short presentation, and present their findings. Click the link below to buy it!

Students can model the process of biological magnification, and learn how it affects them. See the product below.

"The Dragon Project!" is an epic, multi-unit project unlike any you've seen before. It is my student's favorite activity of the year. This three-four week project involves students finding a genome inside an egg, decoding the DNA, identifying the traits of the dragon, building a unique dragon, competing against a population of dragons, analyzing the results, selecting a mate, producing sperm and eggs, and making offspring. It teaches students about DNA, karyotyping, protein synthesis, meiosis, fertilization, data analysis, and the foundation of natural selection and genetics.

The amount of time required to do this may depend upon the level of the class. It takes my "regular" level classes more than 60 minutes to finish. Whether you assign the remainder for homework, or spill into another class is your choice, of course.
You will need:
1. Construction paper (you could use computer paper in a pinch)
This packet is relatively straight forward to work through. There are pictures for any steps that may seem confusing to students, and all the info they will need is found in the background/intro section in the beginning. It is a fun, hands on way to learn about the differences between the DNA in bacteria and eukaryotes.
