While CRISPR has become one of the most talked about gene editing tools in the research community, easy-to-use educational activities that teach CRISPR and related molecular and synthetic biology concepts are limited. Michael Jewett and his team at Northwestern University have created a set of user-friendly educational kits to address just this issue, called BioBits kits. This tool was developed as a broader impacts activity in Dr. Jewett’s currently-funded research (NSF 1716766) , investigating and expanding the genetic code for synthetic applications such as producing non-natural polymers in biological systems, and with collaboration and funding from several other institutions.
BioBits kits contain materials to run hands-on lab activities designed to teach high school-aged students the basic concepts of synthetic and molecular biology through simple biological experiments. Students add the included DNA and water to pre-assembled individual freeze-dried cell-free (FD-CF) reactions. The results are noticeable when the individual FD-CF reactions fluoresce, release an odor, or form a hydrogel (depending on the experiment). For example, the BioBits Bright kit includes six different DNA templates, each of which encode for a protein which fluoresces a unique color under blue light, directly demonstrating how proteins differ based on initial DNA sequence. So far, three kits have been developed: BioBits Bright, Explorer, and Health, with activities covering topics from the central dogma of biology, to genetic circuits, antibiotic resistance, and CRISPR.
The visible (or smellable) outputs make the results interactive and intuitive, engaging students in a relatable experience. In addition to the FD-CF reactions and instructions, the kits contain example curriculum, such as one independent research-based activity that asks students to address ethical questions surrounding CRISPR, further engaging students in the topic and providing a deeper understanding of the technology.
