       Considering most in-person demonstrations of synthetic biology we did cannot be preserved for future review and rebuild, a series of online interactive sessions are essential for the knowledge and work to be spread. To engage a wider range of peers and students to engage in the contribution and participation of synthetic biology journey, we have collaborated with another high school team in Shenzhen called AIS-China to produce a series of synbio courses of 10 lessons, targeting on our peers who cannot easily access synthetic biology resources in their curriculums or on-campus education. This covered topics like central dogma, DNA gel electrophoresis, PCR and parts. Two teams both benefit from this cooperation as we distribute the videos at various situations to different audience. AIS-China team members utilized the videos as an engaging educational tool in the iGEM club at their school.

       Understanding Giant African Snail infection as an local problem in South China, but besides the striking data and numbers published online, we were also curious about whether the species invasion is a global concern that will affect the daily lives of ordinary people all around the world. Gathered information from the Internet, we realized that snails might be part of the local diet in some African areas, where the snails originated. Therefore, we contacted Marlboro Gardens Secondary School in South Africa via email, explaining our purpose for multi-cultural communication regarding the opinions on invasive species, which would significantly enrich the definition of the impacts of our project. 
       <br><br>Building on our initial motivation, our team recognizes the importance of introducing synthetic biology to this specific group. Synthetic biology, being a relatively new field, remains less accessible, particularly to teenagers worldwide. As adolescents ourselves, we've been fortunate to be finanacially and physically capable of access to synthetic biology laboratories and conduct experiments. However, we also recognize the disparities in access to synthetic biology education, especially in African schools.

Furthermore, we aim to raise awareness of our project in light of the health threat posed by the Giant African Snail, which is a significant local concern in South China.

Our team has selected three main platforms: RED, Bilibili and Wechat (the last two are mentioned before) as they are the most trending and influential media in China with millions of enthusiastic users. RED, a platform with a recreational nature provides a diverse range of content forms, including textual, visual, and audiovisual elements for people to share their daily lives.(such as notes, plog and vlog). Here, we integrated our education with the characteristics of this platform to share warm and interesting stories of our daily lives in iGEM journey, revealing how charming synthetic biology labs may look like. This multifaceted approach enhances our ability to effectively communicate our message and captivate the interest of users, hence optimizing the dissemination and appeal of synthetic biology within various demographic segments.

       In response to the feedback from Human Practice activities that there are insufficient efforts contributing to a systematic and standardized operating system regarding the integrated control of Giant African Snails (see Human Practice), and also aid our hardware potential users(see Hardware), we create a Wechat mini program, called Snail Locator, to actively engage our project with the general public in our surrounding society. The printed QR code is presented everywhere at our neighbourhood, anyone who is interested in could scan the code and open the mini program, supported by officers in Wildlife Protection Bureau and members of the Chinese People's Political Consultative Conference in our Human Practice. Then our users can read through information regards to local Giant African Snails issue. As they scroll down, users can upload the geographic locations of where they've seen GAS and attach photos of the snails. On the admin site of this software, we can gather data of areas where GAS congregate or occur frequently. Therefore, our team can offer this information to our Hardware users for recommending distribution site, as well as to local governments to issue responsive and effective guidelines for the target regions with high density of Giant African Snails.

To fulfill this responsibility, our team members created pamphlet containing selected yet detailed information. The pamphlet outlines the threats posed by GAS as both an invasive species and a disease vector, along with recommended actions that can be taken at the individual, community, and government levels.

       Considering that majority of our education has been slightly scattered and random, we are eager to establish more direct conversation with our audience and listen to thier genuine thoughts. Moreover, we have come to realize that the older generation often holds a negative view of gene technologies, with some even refers gene-edited vegetables as "carcinogenic". To dispel the misconception, we organize a introductory lecture facing adult at our labaratory.
       <br><br>This time, we shifted our focus onto the discovery and development of synthetic biology as an scientific subject. Instead of concentrating on the professional terminologies and specific techonologies, we aimed to help our listeners perceive synthetic biology as a subject that allows us to "understand life from the perspective of designing life". This lecture was given both online and offline. Participants who came to our lab also had experienced microbial plate painting experiment as well.
