I recently discovered a great online resource for engineering lessons called the TeachEngineering Digital Library. It's a fantastic collection of educational materials that cover a wide range of engineering topics. The website is user-friendly and easy to navigate. The lessons are well-structured and provide clear explanations along with practical examples. I particularly appreciate the variety of resources available, including videos, worksheets, and interactive games. The TeachEngineering Digital Library has become an invaluable tool for me as a teacher, and I highly recommend it to others in the field.
