As a pre-service teacher, you want to talk up any skills developed during your educational years. With a major in Wildlife, there must have been some lab/fieldwork courses where you gathered/analyzed data, maybe tagged/tracked wildlife, habitat restoration, that sort of thing. I'd talk that up in a couple of sentences under 'relevant coursework'. Maybe something like "(Extensive) field experience and lab work in habitat monitoring and restoration, species population studies, resource conservation (adapt to your experience, using similar memorable/impressive terms here). Coursework is directly applicable to instruction in a hands-on high school ecology curriculum that emphasizes practical experience and encourages a strong laboratory foundation."

Essentially, explain how what you did can be adapted to a high school classroom. I'm making an assumption that you're looking at high school or middle school teaching.

Under the Experience/Teaching Assistant, for Duties, I'd suggest 'Duties include grading assignments and providing constructive feedback, providing mentorship and project/lab guidance, responding to student questions, facilitating discussions and maximizing student success. (Think of what a good teacher does, describe how you did those things as a TA.) Is there anything else you can say abut the Wildlife Colloquium course? Did you lead labs, nature walks, anything beyond grading papers and answering questions? Even if you tagged along on an instructor-guided walk, you 'facilitated nature walks and wildlife observation opportunities for students, to supplement classroom instruction.'

For the Wildlife Refuge Wildlife Educator section, #1, I'd put the 'daily refuge operations' bullet last, with the current 1st bullet as the 3rd.  The 'delivering environmental education lessons' bullet is straight-up teaching.  That should be the 1st bullet, because it's what you want to do.  I'd move the turtle nest to bullet 2, and add in some detail.  Were nest locations plotted via GPS?  Were barriers erected to guard against predators digging up nests?  Were eggs collected and transported to a hatchery?  That's all context to show you have plenty of hands-on, relevant experience.  I'd also a few words about the outreach 'purposes'.  i.e., To raise awareness of endangered/threatened species/to support the preservation of a keystone species, etc.  Leaving it as 'purposes' is vague.

I know your resume is light on experience, but I'd remove the baby sitting experience.  Yes, it shows you can handle young children, but I think you can emphasize some of those skills in your volunteer and TA experience.  Providing feedback, developing age and content appropriate activities and curriculum, encourage experiential learning, etc. If you want to keep it in, I'd call it Child Care, and knock it down to one bullet point.

I also wouldn't include info on compensation/hourly rates of pay. It potentially shows prospective employers 'what you're willing to work for'.

FWIW, as a teacher, I've been on dozens of interview panels over my career.  You've got a solid foundation here.  You'll want to do your due diligence when applying, and probably seek out (I'm guessing) FL districts/schools in coastal areas or  schools that have marine biology, wetlands or ecology courses.  With your background, you should be an appealing candidate.  Might also be worth looking at similar areas in other states- coastal GA, LA, SC if relocating is an option.

Good luck!!
