Voluntary Internships

Hello, I am planning to apply for a voluntary internship in the next term since I will only be taking one major subject. I want to make up for my lack in org experience; however, I don’t exactly know where to start or how to find one that is in line with my course, literature. I don’t mind it being unpaid as I am in it for the overall experience and development of my skills, it’s also in preparation for my practicum. Advice would be very much appreciated!! :))
