Your little one will get an introduction to the important concepts of resistance and electricity while making their Bumble Bee project. This device will allow them to map different electrical devices to resistance in a circuit and learn how adding elements to a circuit changes the resistance. The Online Classroom introduces the key concepts for this lesson, and then the creator will assemble their Bumble Bee, using the detailed step-by-step instructions and diagrams. The Bumble Bee’s speaker changes pitch depending on resistance, so when it’s done, the creator will be able to make a hand-drawn working piano and play songs with it. Then, the Junior Robotics-maker will test their new skills and understanding with challenge questions and exercises.

Lesson Preview

Once the Bumble Bee is assembled, the learner will put their new understanding and skills into action by completing these challenges:

  • Make two rectangles of different dimensions have the same pitch.
  • Construct a parallel circuit where people can take turns leaving it without the sound going off.
  • Look around for different metal objects and see how they change the resistance and sound. Make some music!
