Unit 3 (Materials): Class Presentation

Hi everybody! As you know, we are taking the exam for Unit 3 (Materials) the coming Thursday and Friday. So, in order to recall the main points of this unit (types of materials, properties, objects and materials, woodworking techniques and tools, ...) here (first part and second part) you have the presentation I used in class. Remember you can redo the IT activities here in the blog and, while you are at it, complete your workbook. See you in class.
