Thanks for your question. I agree with Madhu about recommending the Bytes and Beats course for high school students as a start. This is a good way to introduce young students to algorithms and programming, with a fun music component.
We do have drone and aerospace related educational hardware that could be use to inspire students as well. However, at this time it may take some extra effort to really explain how such systems work to high school students.
Simply put, a drone is a flying embedded system that integrates multiple domains of knowledge. They can be used as an example of how disciplines and technologies converge and how investing time in learning to use multi-domain tools like MATLAB and Simulink can pay off greatly in the future career of students.
To learn more about our educational drone solution for undergraduate and graduate students, please take a look at the following webinar: https://www.mathworks.com/programming-drones-webinar
