An issue arising in emergency distance education procedures, such as the response to the COVID-19 pandemic, is a lack of appropriate high-quality content and course activities for high ability students suitable for distance education. In this study, online CAD-based learning experiences structured with the Tinkercad Circuits Platform designed for gifted students were investigated based on the opinions of students regarding the distance education activity and the evaluations of the students' scientific writing skills. This study used a single case holistic design with 10 gifted 6th-grade students at Usak Science and Art Center in Türkiye. All of the students stated that they had not previously encountered an activity such as the "smart air conditioning system". The students also stated that although the activity was carried out in the form of distance education, it was positive and fun to be application-based, and that it was fun to research, discuss, design, and code with Tinkercad to look for a solution to the given problem. The evaluation of students' products showed participants' high level of proficiency in activities requiring advanced problem-solving skills, including planning the solution to the problem, creating an alternative plan for the solution, realizing, and evaluating the design.
