On Friday we wrapped up our Structure and Function unit in science by designing and building paint brushes.  Students were presented with the challenge of creating a better paintbrush.  Their first step was sketching several designs and choosing the one they would like to make.

Then they were invited to go "shopping", choosing from a variety of materials to build their paintbrushes.  Some of these included dowels, craft sticks, toothpicks, pipe cleaners, foam, pom-poms, and feathers.  Once materials were gathered they set to work building, resulting in a wide range of new paint brushes!

At the end of the day they were given an opportunity to test their finished products.  Finally, after using their own brushes and observing the creations of their classmates they were asked to think about changes they would make in their design if they could make the paintbrushes again.
