Can I get a teaching liscence or certificate in Ohio without majoring in education?

I live in Ohio and I have a bachelor of geological science. I would like to take the Praxis test so that I could teach. But I need to know if I can do this or if I need to go back to college for 2 more years to get my master’s in education? And if I went back to college I would want to major in Geological Science, not education, so could I still get the teaching liscence? Help?

And then is there a difference between a teaching liscence and a teaching certificate? I really would like to be a earth science teacher for an online k-12 school, but need the paperwork and liscence or certificate to do so. So I am looking to do the quickest and easiest steps to get liscenced or certified in Ohio to teach.
Can anyone help me out with this? Or at least point me in the right direction.

I believe you can teach with a Bachelors in any area without an Ed degree as long as there is a need. You need to call your dept of education (link provided below) and ask them about this. I know in other states they can issue you a temp license for 1-2 years in an area of need to teach in the classroom (depending upon if you pass the background check and a couple of small requirements). For your specific area and location, you need to inquire with them. They will walk you through exactly what you need to do to achieve a teaching license.
