Lesson 11: On the Move with Events
Overview
In this online activity, students will have the opportunity to learn how to use events in Play Lab and to apply all of the coding skills they've learned to create an animated game. It's time to get creative and make a story in the Play Lab!
Purpose
Students will further develop their understanding of events using Play Lab today. Events are very common in most computer programs. In this activity, students will use events to make a character move around the screen, make noises, and change backgrounds based on user-initiated events.

Objectives
Students will be able to:
- Identify actions that correlate to input events.
- Create an animated, interactive story using sequence and event-handlers.
- Share a creative artifact with other students.
Preparation
- Play through the puzzles to find any potential problem areas for your class.
- (Optional) Pick a couple of puzzles to do as a group with your class.
- Review CS Fundamentals Main Activity Tips - Lesson Recommendations.
- Make sure every student has a Think Spot Journal - Reflection Journal.

Teaching this course as a class?
Our grade-aligned CS Fundamentals courses use unplugged lessons to build community and introduce tricky computer science concepts, including events. Check out the lesson The Big Event Jr. from Course A!
Introduction
Now we're going to add events to our code. Specifically, we're going to have an event for when two characters touch each other.
- When have you seen two characters touch each other as an event in games?
Bridging Activity - Events (10 min)
Previewing Online Puzzles as a Class
Pull a puzzle from the corresponding puzzles online. We recommend puzzle 7. Call on different students to make a funny noise when you click on Jorge. Explain this is an event that they are reacting to and Jorge can be coded to make noise when you click on him.
Main Activity (30 min)
Online Puzzles and Free Play
At the final level students have the freedom to create a story of their own. You may want to provide structured guidelines around what kind of story to write, particularly for students who are overwhelmed by too many options.
Wrap Up (5 - 10 min)
Journaling
Having students write about what they learned, why it’s useful, and how they feel about it can help solidify any knowledge they obtained today and build a review sheet for them to look to in the future.
Journal Prompts:
- What was today’s lesson about?
- Draw one of the Feeling Faces - Emotion Images that shows how you felt about today's lesson in the corner of your journal page.
- Draw an event you used in your program today.
- Imagine that you have a remote controlled robot. What would the remote look like? Draw a picture of what you think you could make the robot do.
Extended Learning
Use these activities to enhance student learning. They can be used as outside of class activities or other enrichment.
Look Under the Hood
When you share a link to your story, you also share all of the code that goes behind it. This is a great way for students to learn from each other.
- Post links to completed stories online.
- Make a story of your own to share as well!
- When students load up a link, have them click the "How it Works" button to see the code behind the story.
- Discuss as a group the different ways your classmates coded their stories.
- What surprised you?
- What would you like to try?
- Choose someone else's story and click
Remixto build on it. (Don't worry, the original story will be safe.)

Help Jorge the Dog get moving by connecting the move dog west block to the when left arrow event block that is already in the workspace.
Get Jorge to the flag to finish this level!
Student Instructions
Now, add another event block to get Jorge to move right when the right arrow button is clicked.
Student Instructions
Add events to have Jorge move up and down when the up arrow and down arrow buttons are pressed.
