Lesson Guide


Introduce littleBits Students explored the Bits modules and learned how to create basic circuits combinations.


Design Challenge Students were asked to create something that used a blue, pink and green module. The challenge was completely open-ended.


Brainstorm Ideas The students worked in groups of 2 or 3 and had to do some initial planning in their science journals.


Design and Build Students used littleBits + classroom materials to build their engineering projects.


Document and Share Each group helped make a video to describe and show their project in action.


Reflect Students finished the unit by compiling notes about their inventions and reflecting on the experience.

The projects were then displayed for the rest of the school to see!
