College freshman with 10K. What should I invest in?

I am currently a freshman in university. I would like to see what possibilities are out there to invest in.

Through the past years, I’ve worked and saved up here and there. Now, I have roughly $10,000 in my bank. I have good scholarships for school, so I only have to spend 3,000 a year for tuition. Thus, I am thinking I could invest 5K into something. But I have no experience with investing… what is there? Is this a good time to start?
