Yesterday astronauts on the International Space Station had to go to emergency shelters due to space junk (https://www.theverge.com/2021/11/15/22782946/russia-asat-test-satellite-international-space-station-debris). The idea of space junk and rogue satellites causes many issues for governments and companies. Interestingly enough though, you and your students can track satellites and other space debris using this LeoLabs interactive resource: https://platform.leolabs.space/visualization. Check this website out and see what you can do.
I also recommend to try searching for Starlink in the LeoLabs interactive and check out the possible future of internet access (https://www.discovermagazine.com/technology/how-do-spacexs-starlink-satellites-actually-work).
