Project Lead the Way: Make a Paint Brush

Last week we completed the first module for PLTW. Students needed to build a paint brush that met the following criteria:

1. paint thick lines
2. paint  thin lines
3. paint squiggly lines
4. paint polka dots

• After we talked about what the paint brush needed to do, we discussed what materials we could use to make this project and then students drew two design ideas.
• When their designs were drawn, students had access to various materiel and made their paint brushes.
• They were then directed to test their design by painting with it.
• If a student's paint brush didn't meet the criteria, they discussed how they could improve their design.
• The last item in this module was to draw an improved model of their design and write a sentence about it.
