Hi Abby, great question! It's likely that you can get involved in city government as a volunteer or program participant! For example, many cities have "sister city" organizations, where you can join in as a citizen to help develop good international relations and organizational skills. Several people on our city council started within the sister cities organization, so it's been a great entry point to bigger responsibilities. For science advocacy, at some point look into becoming a member of a professional organization. They are great networks that often include political advocacy as well. For example, within the engineering field, the IEEE is such an organization (for example, see https://www.ieee.org/membership_services/membership/societies/about_technical_councils.html and https://www.facebook.com/ieeeyp/).
