Universal Leonardo June 16, 2008 by Larry Ferlazzo | 1 Comment I learned about Universal Leonardo from TechLearning. It has a bunch of great online interactive experiences students can have with Leonardo da Vinci’s drawings and experiments. I wish I had known about this site when we went on a field trip to the da Vinci exhibition earlier this school year. I’ve placed the link both on my Science and World History pages.
