2.1.1 Activity Process

During the summer vacation, we came to Yuxin Garden Community and organized a education activity about “The Magic of DNA”. Our activity was structured into two parts: an lecture and a hands-on workshop.

In the first part, we introduced the fundamental concept of DNA through an accessible and engaging presentation. Beginning with visible traits such as variations in skin and eye color, we illustrated how DNA determines individual characteristics. The session also included a brief introduction to the four DNA bases—Adenine, Thymine, Cytosine, and Guanine—and explained their complementary pairing rules.

The second part involved a practical model-building activity. Using pipe cleaners and colored markers, the children constructed their own DNA models. Each color represented a specific base (A, T, C, or G), allowing participants to visualize the structure and pairing of nucleotides. To conclude, the children presented their models and shared what they had learned about DNA’s role in living organisms.

2.1.2 Feedback and Impact

We gathered feedback from parents following the event. They indicated that the activity was highly effective in disseminating basic knowledge of DNA and appreciated the hands-on approach using pipe cleaners, which significantly enhanced the children’s engagement. The complexity of the content was deemed appropriate for the age group, making learning both effective and enjoyable.

Some parents suggested incorporating more interactive elements, such as additional Q&A sessions during the explanation phase, to foster even greater participation. Based on children’s responses during the model-making activity and a follow-up quiz, we observed that the session successfully broadened their understanding of DNA and sparked interest in its biological functions.

2.2.1.Activity Process

We effectively leveraged our school's Science Fair as a platform to conduct an educational outreach event focused on synthetic biology. Our team independently designed and produced visually appealing and informative display boards.

The core content of our exhibition highlighted the history, fundamental principles, and diverse real-world applications of PCR technology.

Additionally, we prominently featured our team's research on the natural sweetener, erythritol, clearly outlining our unique research focus and advantages. During the event, we engaged in in-depth discussions with visiting students and teachers through on-site explanations, interactive Q&A sessions, and the distribution of educational materials.

Feedback and Impact

The outreach activity received positive and enthusiastic feedback. Many visitors, especially students interested in biotechnology, expressed that our presentation provided them with a more intuitive understanding of PCR technology and sparked a strong interest in the health benefits of erythritol. This event not only successfully enhanced participants' awareness of cutting-edge fields in synthetic biology but also significantly improved our team’s skills in science communication and organizational coordination, fostering a positive atmosphere for scientific exploration within our school.

2.3.1.Activity Process

We conducted an educational activity for eighth graders on the magic of DNA—making DNA models. First, we introduced what DNA is and its importance in life. We also taught the basic principles of base pairing and how ATCG functions in the body to form characteristics. The students were very interested and actively raised their hands to discuss this. Next, we had the students build a DNA model. The eighth graders used a twisting rod to construct the DNA structure, colored it with watercolor pens, explained the roles and functions of ATCG, and finally connected it into a long DNA chain.

Figure 9 Students' Feedback

After the activity, we collected feedback from the students. Most of them were very satisfied and found the activity both fun and engaging. Some students suggested that the content could be slightly more challenging. We truly appreciate this valuable input and will take it into consideration to improve future activities.

To help a broader audience grasp the fundamental base-pairing rules (A-T, C-G) and understand how subtle changes in DNA can lead to significant trait variations, our team developed an interactive matching game. Players drag and drop puzzle pieces labeled A, T, C, and G to form correct pairs. Each successful match alters one feature of a character’s appearance, and completing the entire sequence reveals the full figure.

Figure 12 Our Rednote Account

To promote synthetic biology and the natural sugar substitute erythritol to the general public, we launched official accounts on Rednote and WeChat. Through these platforms, we introduced the scientific principles and practical applications of synthetic biology, and explained the important role of erythritol as a safe, low-calorie natural sweetener in a healthy diet. By sharing engaging and easy-to-understand content, we helped the public build a scientific understanding of sugar substitutes, clarified common misconceptions about sweeteners, and aimed to promote awareness of healthy eating habits.

Figure 13 Our team's Badge

We have designed some badges that use vibrant and engaging visuals to draw public attention to erythritol as a healthy sugar alternative. Each badge creatively combines candy motifs with our team’s symbols, making the concept both appealing and educational. Wearing them not only encourages a sense of involvement but also sparks conversation around sugar reduction and healthier lifestyle choices.

This poster provides a scientific introduction to erythritol, detailing its properties as a four-carbon sugar alcohol produced through glucose fermentation, along with its refreshing sweetness, high stability, and cooling sensation. It also contrasts genetic engineering with synthetic biology, which aims to create artificial biological systems.

Figure 15 Daily Sugar Intake Self-Check

This self-check table offers a practical way for individuals to monitor their daily sugar intake and compare it with the recommended usage. Designed for ease of use, it includes reference values for sugar content in common foods and suggests healthier alternatives. By encouraging self-assessment and gradual habit change, this tool supports a conscious transition toward a reduced-sugar lifestyle.
