This week, I introduced the Design Process to my K5 classes.  Given a box of materials, the students were asked to design a snowman that could stand on its own and not fall over when blown with wind (a hair dryer).  We talked about the need to create a plan, try it out, and then revise or start all over if needed.  The students did a great job of using the materials in different ways to build a snowman.  Most of their snowmen even withstood the wind from my hairdryer!  The groups that did need to revise or start all over did have some difficulty finishing.  This lesson was a great reminder for me that my students need more time than I think (or plan) to make mistakes, learn from them, design a new plan, and then have time to try their new design out.
