The goal of this activity is to build critical thinking skills and excitement for Computer Science / Computational Thinking, while laying a foundation of fundamental programming concepts. By scaffolding basic concepts like sequencing and algorithms in an unplugged activity, students who are intimidated by computers can still build a foundation of understanding. In this lesson, students will learn how to develop an algorithm and encode it into a program.By "programming" one another to draw pictures, students experience some of the core concepts of programming in a fun and accessible way. The class will start by having students view a video of a simple program demonstrating how to develop instructions for building a peanut butter and jelly sandwich. Students will start with simple shapes, and progress to the coding of a specific drawing that other students will then try to replicate (“running the program”). If there is a desire to have a more of a Math slant on the lesson, the drawing could take place on graph paper. Students would then use the coordinates to complete the drawing.
This lesson is part of the Virginia K-12 Computer Science Pipeline which is partly funded through a GO Virginia grant in partnership with Chesapeake Public Schools, Loudoun County Public Schools, and the Loudoun Education Foundation. In this lesson, students will create examples of gravitational potential and kinetic energy transformations using Scratch.
