Description

What kind of toothbrush do you use—manual or electric? What is the shape of the head and the handle? Could you describe the firmness and the layout of the bristles? Or count the number of bristles? In this 5E Model lesson, students explore various manual toothbrush designs. This free sample chapter also includes the Table of Contents, Preface, and Index.

Is There a Better Bristle? - Ch 9 of Putting the
  Reviewed by: Patricia (Arlington, VA) on June 18, 2012
  There are insights on engineering design throughout the chapters in this book, Putting the E in STEM. Chapter 9, Is there a Better Bristle takes the budding engineer into the design process for a toothbrush; there could even be some ‘reverse engineering’ here. If I were to use the ideas presented in this chapter, I would also have my students do a bit of research into the past 20 years of ExploraVision Awards program winners and discover what earlier youthful engineers devised for the future, which is now. This time journey may be very instructional and also exciting for the students. This could take the lesson provided beyond the 5E model to encompass the 7E model and provide a more open-ended opportunity for students to explore, explain, and extend.

I really like the engineering activities
  Reviewed by: Susan German (Hallsville, MO) on May 2, 2012
  Dr. Moyer has been writing engineering activities in Science Scope for a while. Each article has been great. This book chapter is no different. Students will develop a toothbrush. I would like a better picture showing the set up. Beyond that, another great article.
