This is a lesson that introduces/reviews electricity, currents, and energy and then introduces students to Little Bits. Students will learn what different Bits do, brainstorm something to create using Little Bits, and complete different circuits. Little Bits are small electronic pieces that snap together magnetically to form bigger circuits. They are easy-to-use with no wiring or programming needed. (Most appropriate for grade levels 4-8.)
Lesson Time: 60 minutes
Student Activity 1: Students explore how Little Bits connect and learn what the different bits are and what they do. They will discuss the possible uses for the bits as they try them out.
Student Activity 2: Students will work with their groups to brainstorm a problem they can solve with a Little Bits creation. They will build and test their prototype, and should be able to explain their invention before moving on.
Student Activity 3: After reviewing that a circuit is a closed path for electric current to flow groups will complete Little Bits circuits.
Group work: Students should work in groups 4. In order to save time, teachers are asked to create the
groups before our Wizard arrives.
Science Standards:
3.PS.3: Heat, electrical energy, light, sound and magnetic energy are forms of energy.
4.PS.2: Energy can be transferred from one location to another or can be transformed from one form to another. Electric circuits require a complete loop of conducting materials through which electrical energy can be transferred. Electrical energy in circuits can be transformed to other forms of energy, including light, heat, sound and motion.
6.PS.3: There are two categories of energy: kinetic and potential.
7.PS.4: Energy can be transferred through a variety of ways.
Technology Standards: Strand: Design and Technology
Topic 3: Demonstrate that solutions to complex problems require collaboration, interdisciplinary understanding, and systems thinking.
Topic 4: Evaluate designs using functional, aesthetic and creative elements.
