There was a mini STEM fair for primary students at Hong Kong Baptist University Affiliated School Wong Kam Fai Secondary and Primary School. Our Una boards were used by G1 students to practice coding and controlling the robotic cars. Once they were ready, they would move on to the next challenge which is to lead the car move without making the paper boxes fall off. Our Una boards are specially designed to be adaptive and durable for STEM activities (including classroom teaching and competition). We were glad that the students had a great time playing with the Una Board and create their own maze.
