 * Situation**: You are to build a structure that keeps the largest weight 1-1/2 " off of the workbench. Each team gets 1 box of toothpicks. Each team gets the use of an Xacto knife. No other materials may be used.


 * Research**: All truss-style structures would be worth of research


 * Materials**: 1 box of toothpicks. Xacto knife. 2 human brains.


 * Evaluation**: You will be evaluated as shown in the rubric below:

Simply put you are to keep as much weight 1-1/2" off of the workbench. The sag in your structure cannot cause the weights to get any closer than 1-1/2" to the workbench

Evaluation:

 * **CATEGORY** || **4** || **3** || **2** || **1** ||
 * **pencil sketches of 3 different ideas //idea vetting //** || The optimum idea is clear. All sketches are clear and pullouts on the sketches reflect any design points critical to the solution. || Generally optimum idea is clear. Overall, sketches are clear and pullouts on the sketches reflect any design points critical to the solution. || The winning idea is generally clear. Some sketches are unclear due to lack of pullouts or explanation. || There is no obvious winning design sketch. Many areas are unclear due to lack of pullouts or explanation ||
 * **Quality of construction/success of structure**
 * ** || Judicious use of tools lead to an exemplary product. No glue stains or rough edges || Small errors in the use of the tools results in a product that is completely acceptable, but does contain noticeable flaws || The product has many distracting elements but the tool use is obvious. || Either in following the steps, or mistakes in the use of the tools, the work is largely flawed. ||
 * **Ingenuity of design/success of structure**
 * ** || Complex shapes or patterns leads to entertaining product || Overall the piece is well constructed, but misses opportunities to make the product more entertaining || Generally the piece is satisfactorily constructed, but the end result is lackluster || The piece is incomplete, or shows signs of obvious neglect in process. ||
 * **Use of Time**
 * ** || Used time well during each class period (as shown by observation by teacher, and documentation of progress in journal) with no reminders. || Used time well during most class periods (as shown by observation by teacher, and documentation of progress in journal) with no reminders. || Used time well (as shown by observation by teacher and documentation of progress in journal), but required reminders on one or more occasions to do so. || Used time poorly (as shown by observation by teacher and/or documentation of progress in journal) in spite of several reminders to do so. ||
