3-5 Computer Science - Green - Unit 2 Events

green cat

In the second unit, students will investigate the computer science concept of events through the Use - Modify - Create framework by first being introduced to the concept through a variety of multimodal activities, then exploring it in Scratch before creating their own original About Me project in Scratch incorporating this concept. Students will also collaborate on computational artifacts, debug problematic programs, provide feedback on each other's work, and reflect on their own progress throughout the unit.

Sequence of Lessons

Discover: Sequence Green Level: Unit 1, Lesson 1

View the Lesson Plan - G1-1: Discover - Sequence

Lesson Overview

Students will be introduced to the computer science concept of events by interacting and tinkering with projects that use a variety of event blocks including but by no means limited to the When Green Flag is Clicked, which they may already be familiar with from ScratchJr. in K-2 lessons.

Agenda

  1. ๐Ÿ”ฅ Warm-up: Review Computer Science Norms. What do you remember about computer science from previous grades? If this is your first time learning computer science, how are you already using computers to be creative?

  2. โ–ถ๏ธ Main Activity: Watch Scratch Overview video. Model the TIPP & SEE Protocol with the Scavenger Hunt - Under the Sea project. In partners, students complete a hardcopy or Google Form activity page then continue to make changes to the Under the Sea program to personalize it.

  3. ๐Ÿค” Debrief: How did you and your partner change the project to make it more โ€œyouโ€? What is something you can thank your partner for today?
