So for my third year engineering class, I have to present three possible topics for me to research all year long on the first day of school. I am pretty much interested in everything, but I need a topic that I can research all year long, and can be related to any aspect of STEM. It should also be a somewhat new idea/invention/ creation that I can learn about and hopefully work upon in my own way. If you guys have any ideas or topics that you would like to share, please tell me! thanks 
gizmag, gizmodo, and other online magazines have some really cool topics and ideas that might help you get started. There is a large range of topics that these magazines cover, including new tech, new research, and alot of other things. Take a look around!
