Science is not only for people who already know the answers. Scientists begin with questions. Engineers begin with problems. Inventors begin with ideas. Pick something that makes you wonder “why?” or “what if?” and start there.
A note for students
Use the internet like a scientist.
Check who created a resource, look for evidence, compare more than one source, protect your personal information, and ask a teacher or trusted adult before creating accounts or sharing information online.
