Hi, my name is Fern, and I volunteered as an inner-city school teacher after I finished college. Many of my students had never been outside of the city, and although I couldn't take them into the mountains or the forests or even on a field trip to a farm, I wanted to give them a semblance of that experience. I ended up using audio-visual equipment to simulate a natural environment. My students were able to see grass blowing in the wind, time-lapse videos of trees growing, and they were surrounded by the sounds of nature. If you want to use audio-visual equipment to teach kids about nature or any other subject, check out my posts. They will guide you toward excellence.
