Science Fair Description
On Wednesday, September 12, we hosted a Biology Fair at the Carmel Valley Library in the Community Room from 3:00-5:00 pm. Our goal for the fair was to give young students in the community exposure to the life sciences and to potentially spark their interest in learning more about biology. We set up 8 different stations around the room that all had simple activities for the students to try, and different members of the team attended to each station to help the students participate in the activities and to answer questions. Some of the activities that students could try included participating in an online Kahoot! quiz on the work of ecologists, using marshmallows and toothpicks to make a model of the DNA double helix structure, matching DNA with RNA and RNA to amino acids, building models of proteins, guessing the number of chromosomes in different organisms, practicing using a microscope to look at common items and using pipettes to transfer colored water, and making models of plant and animal cells with candy. Students seemed to enjoy learning about all of the different subjects and getting to do hands-on activities, and they gained exposure to both basic concepts of biology as well as simple lab procedures.

Interview
On Friday, September 14, some of our team members visited Professor Eric Schmelz’s lab at the University of California, San Diego to discuss our project and ask for feedback on it. We inquired about background information on fungi and bacteria’s effects on plants, potential ethical issues that could arise from the development of our project, how to address those issues, and suggestions and improvements for our project. From this interview, we learned that different fungi have different effects on the growth of plants, and that these effects can be both positive or negative, and Professor Schmelz reminded us of previous cases in history where fungi and bacteria had significant negative effects on plants. We learned how people have overcome the threats of fungi and bacteria on plants in the past, such as by creating more diversity among plants so that those that are resistant to the fungi and bacteria are able to populate. We learned that there are political and religious issues that need to be addressed, and the unknown effects of altering certain jumping genes on the human body. As for suggestions for our project, Professor Schmelz encouraged us to try enzyme evolution to further expand the scope our results, and we integrated his suggestion into our wetlab work as part of the project.
