Monday:

 * INTRODUCTION:** Select **4 of the videos t**o watch. As you watch, **take notes and sketch ideas** (what is a trebuchet? How does a trebuchet work? What are the different parts of a trebuchet? Which parts seem essential to making the trebuchet work? … etc) You will use your notes/sketches to help you create your own table top trebuchet in class.


 * videos:**
 * The Medieval Trebuchet (a NOVA clip) (7m31s)
 * Trebuchet siege artillery (2m45s)
 * physics lesson on trebuchets (5m40s)
 * Crafstman experience - trebuchet model (watch from 1:54 - 4:42)

 * [[file:trebuchet History and Mechanics Worksheet.pdf]]
 * [[file:trebuchet history and mechanics rdg.pdf]]
 * Use your learning to help you create a proposal for your trebuchet design. You will present your design to peer groups and record their feedback. You may use any new learning / suggestions to redesign your proposal.
 * [[file:trebuchet planning doc.pdf]]

**WEDNESDAY/ THURSDAY**

 * complete your planning phase. You will not be given any adhesive materials until you have:
 * a sketch of your building plan
 * a list of the materials you will use (including amounts of each item)
 * a documented praise/polish from at least 2 other teams
 * Once you show me these items, you may begin the construction phase. I will give you tape and glue to start your work
 * During construction you may decide to make changes to your design. This is ok - just make sure to create a new sketch and revise your materials list.
