Mark DNA Day with a Field Trip, a Genome Refresher, or a Spool-Your-Own DNA Activity
That's a lot of DNA, a lot of letters, an almost incomprehensible amount of typing, and a lot of room for little mutations, changes, exceptions, similarities, and differences! This year, in celebration of National DNA Day (April 25, 2014), take time to talk with your students about DNA, genomes, and genomics.
Last year, for the 60th anniversary of the discovery of the double helix structure of DNA and the decennial marker of the completion of the Human Genome Project in 2003, we pulled together a short overview of the history of DNA, its key players, Photo 51, and great DNA-related science projects that students can do to explore DNA in Celebrating DNA and the History of the Double Helix.
A DNA history lesson or refresher is never a bad idea, but when you pair the information with a simple experiment or hands-on activity, you give your students the opportunity to see firsthand what it means to talk about DNA base pairs, how DNA differs from a genome, and how DNA is essential to all living things!
Genomics Field Trip
For those in the Washington D.C. area, celebrate National DNA Day with a trip to the Smithsonian Institution! The Genome: Unlocking Life's Code exhibit (opened June 2013) is a great way to help students better understand DNA, the ways in which DNA is structured, sequenced, and analyzed by scientists, and the way DNA research helps scientists better understand the past, present, and future.
A collaboration between the National Museum of Natural History (NMNH) and the National Human Genome Research Institute (NHGRI), the 4,400-square foot Genome: Unlocking Life's Code exhibit introduces visitors to the human genome and the role of genomics, the ways in which the genomes of other species show both similarities and differences, the impact of genomics on studies related to human origins, and the use of genomics in the future, particularly in health care.
Visitors to the Smithsonian exhibit can also get hands-on in the National Museum of Natural History's interactive Genome Zone. The Genome Zone houses a rotating queue of activities where students can examine their own traits, do lab experiment, make bead bracelets that show the genetic sequence of a chimpanzee or turtle, watch videos, and more.
Sampling Your DNA
In the Genome Zone, visitors may have the chance to extract a sample of their own DNA using the Genes in a BottleTM kit from Bio-Rad Laboratories. After extracting DNA from a cheek sample, students can admire it and possibly even take it home as a keepsake! Thanks to support from Bio-Rad, approximately 300 student Genome Zone visitors a day are getting up close and personal with their own genetic material—spooling their own DNA.
Thanks to the Genes in a Bottle kit and the Discovering DNA: Do Your Cheek Cells & a Strawberry Both Have DNA? Project Idea, visualizing DNA can be a simple, fun, at-home or at-school activity. At the end of the science experiment, students using the kit can preserve their DNA sample as a cool, one-of-a-kind pendant.
Support for Educators
For those not in Washington D.C. area, or for teachers and parents planning to take students to the exhibit, Genome: Unlocking Life's Code Educator's Guide for Teachers of Grades 7-12 is an excellent PDF resource. The 36-page guide contains supplemental information for a field trip to the exhibit and also offers summary information, a number of classroom activities (including printable assignment sheets), information tying Next-Generation Science Standards (NGSS) to the exhibit, a glossary, and a range of resources for science, technology, engineering, and math (STEM) education.
