Buzz, Blink, Whirl: Electric Circuits Simplified


Buzz, Blink, Whirl

This lesson is designed for introductory physics students as a way to demonstrate their understanding of electric circuits and motors. Students will create an interactive children’s book that explains electricity and magnetism in a simple and engaging way.

LESSON GUIDE

STEP 1 : Setup

Ideally, this lesson is completed individually. Each student will need a copy of the Little Bits Invention Log and access to a variety of Little Bits, which can be kept in a central area of the classroom. The focus of this activity/assessment is to allow students to use Little Bits to communicate their ideas effectively. Teachers should guide students to think critically about how they will convey their message about electricity and magnetism using a combination of words and diagrams in addition to interactive elements.

STEP 2 : Connect

Review the major differences between series/parallel circuits and the right hand rule for a motor. This could be completed as a Kahoot Quiz or other form of formative assessment as students should be familiar with these concepts before beginning this activity.

STEP 3 : Teach

Show examples of children’s books with pop ups, pull tabs, etc. Engage students by brainstorming which elements make the best children’s books.

STEP 4 : Engage

Students should already be familiar with Little Bits from a previous activity, therefore, before distributing any bits, have students complete pages1-6 in their Invention Log. At the beginning of Period 2 (after planning stage), the teacher should speak with each student and review their storyboard and list of necessary bits.

STEP 5 : Practice

Have students begin to build their books. Ensure that they are focusing on not just the Little Bits, but the entire book including their writing and construction.

STEP 6 : Close (Gallery walk)

Arrange the books on long tables so that students can explore their classmates creations. You could even invite elementary students, if possible, as a real test of the book’s effectiveness.
