Technology and Trees.ppt
This presentation discusses using a schoolyard tree project to teach science concepts through a multi-disciplinary approach. It involves having students identify and inventory trees, calculate the environmental benefits of trees, and map the trees using Google Maps. The project aligns with state science standards and also teaches skills in tree biology, urban ecology, classification, and using technology. It requires minimal materials and can be done during spring and fall. Details are provided on how to identify trees, conduct an inventory, calculate benefits using online tools, and create a tree map. Resources for tree identification guides, curriculum, and setting up a school tree nursery are also listed.
