Seeing is believing! At our Let's Talk Science Booth, high school students had the opportunity to extract DNA from strawberries while learning about its structure and how it is packaged inside cells. We guided the students through the extraction process, describing the purpose of each step, and invited them to consider the chemical and biological processes behind what they were doing.

For high school teachers who were present, we also discussed how experiments like DNA extractions can be brought into the classroom in order to teach students about genetics and DNA. The high school teachers shared with us that synthetic biology is rarely encouraged as part of the science curriculum, but that many teachers and students show an interest.  Based on this, we decided to try reach out to more students in order to spread the word about synthetic biology to the next generation of scientists.

Minds in Motion

Every summer at the University of Calgary, groups of elementary school students can be found in labs and classrooms learning about science, engineering, and technology. This educational setting is provided by Minds and Motion, a summer camp run by the University. For four groups of students, synthetic biology also became part of the curriculum.

We taught an hour long lesson on DNA structure, function, and modification, and introduced the theme of synthetic biology to encourage students to think about the many possibilities that science and engineering create.

For older groups of students, we designed a genetic engineering game, with balloons representing bacterial cells and yarn as DNA. We had the students simulate growing bacteria by inserting yarn-DNA into the balloons and blowing them up. We then taught them how to extract the DNA by lysing the cells (popping the balloons). Students cut up their yarn genomes and worked in teams to create genetic circuits, with different colors of yarn representing different genes and circuit elements. They then reinserted their modified DNA into a new balloon and blew it up to once again grow their genetically engineered cells. In pairs, we had the students what genes they added and what traits these genes would give their cells. The students then popped the balloons a second time, and we talked about how they would analyze a genome using gel electrophoresis. Our last exercise had the students order their digested ‘gene fragments’ by size so they could understand how we would confirm DNA has been transformed into a cell.

For the younger group of students, we created a similar activity but with paper plates as the bacterial cells. Students were encouraged to think of genes they would insert into their cell through genetic engineering, and then used craft supplies to show us what their cell would look like.

TELUS Spark Adults Only Night: Hack It

Students aren't the only ones that can get excited about science! At TELUS Spark’s Adults Only Night, the theme of the event was ‘hacking’ the world around us using science and technology. Genome editing is the ultimate biological hack, and we introduced participants to the topics of genetic engineering and synthetic biology. We had participants help us perform a DNA extraction from strawberries, but this time using ingredients to make a DNA-strawberry cocktail they could drink. Again, we discussed the structure of DNA and the biological processes behind each of the steps in our procedure. We received many questions about how this procedure would translate to a lab setting and what extracted DNA can be used for, which gave us plenty of opportunities to discuss lab techniques and biotechnological applications. Synthetic biology was a new topic to many participants, but sparked curiosity and interest.

We also organized a game of radioactive dodgeball as a fun way to introduce attendees to the specifics of our project and show how ionizing radiation can damage DNA. Dodgeballs acted as ionizing radiation, and participants were pieces of DNA. When damaged with ionizing radiation, participants became "mutated" and lost the use of a limb. DNA-participants were only able to rejoin the game after being healed by appointed team doctors carrying an imaginary version of the radioprotective peptide mBBI.

For our final event of the season, we worked with the University of Calgary’s Biological Sciences Graduate Student Association to arrange activities at Beakerhead and Beakernight: Calgary’s annual art, science and engineering festival. We set up a booth for three days in downtown Calgary where Calgarians could ‘paint’ a petri dish with fluorescent Escherichia coli cells. On the fourth day after incubation, we displayed these painted petri dishes and invited participants to come view other masterpieces and look for their own work of art. As people waited to look at the display, we talked to them about how the fluorescent E. coli had been made through the process of bacterial transformation and how we protect the safety of lab workers, public participants, and anyone who comes into contact with lab strains of bacteria.
