When I was a little girl and living in Morris County, my father would take me on the weekly trips to the local recycling center when the weather was nice. I remember how much fun it was to take out all the items from our trunk and toss them into their appropriate dumpsters. These things were monstrous! This taught me, early on, about how to recycle. In school, I learned the importance of it.
In sixth grade, I chose Groundwater as my science fair project and my father helped me to build a ‘working’ cave that would allow water to seep through the top of the ‘cave’ (made of clay and other things) and out the bottom of a storage basin. For this, we needed a mesh screen. So, to the recycling center we went for the parts we needed!
Take children to the recycling center. Educate them there. Collect a few items (clean them with a bleach and water solution) and do a craft. I know that people do this already with items in their homes, but if you really want to teach about recycling, you should go to the place where your recycling goes.
