This activity was designed and implemented as a closing event for the eTwinning project "SUSTAIN WELL" on the last day of school before the summer holidays. It was organised by teacher Constantina Stephanou at Kampia Primary School, Cyprus, and involved all students from Grades 1 to 6 (ages 6-12).

The Concept
The entire school day was dedicated to SUSTAIN WELL! activities, with students working in mixed-age groups to take on programming challenges using Blue-Bots. The missions were designed to promote sustainable behaviours during the summer break, with all activities explicitly linked to the 17 Sustainable Development Goals (SDGs).

The Challenge: 20 Summer Missions & 4 Trap Squares
Students became "Sustainability Agents" with a mission to program the Blue-Bot to make sustainable choices. The large floor mat featured:

20 Mission Squares with summer sustainability scenarios (e.g., saving water, protecting sea turtles, choosing local products, ensuring equal access, reducing waste)
4 Trap Squares representing unsustainable behaviours that the robot must avoid ("The Garbage Trap", "The Waste Trap", "The Selfishness Obstacle", "The Red Zone")

How It Worked

Students worked in mixed-age groups (Grades 1-6), with older students acting as mentors.
Each group received mission cards describing a sustainability scenario (see examples below).
They had to program the Blue-Bot to navigate to the correct square representing the sustainable choice.
Special Rules:
- The robot must avoid all 4 trap squares – if it lands on one, the team must explain why that behaviour is harmful and return to the previous safe square.
- Some missions included additional programming challenges, such as using backward moves for the final steps.
- The goal was to complete as many missions as possible while making sustainable choices.

Reflection & Celebration
The activity concluded with a whole-group reflection in which students shared what they had learned about sustainability and how they could apply these habits over the summer. The day ended with a celebration of their achievements as "Sustainability Agents," reinforcing the message that every small action counts toward a better planet.

This activity successfully demonstrated how robotics can be used to teach environmental responsibility, promote teamwork across age groups, and create a meaningful, memorable closing experience for the school year. It was a perfect example of how the SUSTAIN WELL project integrated sustainability, technology, and collaborative learning.
