Lesson 21: Alien Dance Party

Event | Sprite Lab

Overview

This lesson features Sprite Lab, a platform where students can create their own alien dance party with interactions between characters and user input. Students will work with events to create game controls.

Purpose

Students will use events to make characters move around the screen, make noises, and change backgrounds based on user input. This lesson offers a great introduction to events in programming and even gives a chance to show creativity! At the end of the puzzle sequence, students will be presented with the opportunity to share their projects.

Introduction

Today students will visit events in programming.

Demo: Ask the students to raise their hands in the air.

What you did was declare an event. When you say "raise your hands in the air" the students responded by raising their hands. In coding, you would declare this by saying something like "when I say 'raise your hands,' you raise your hands".

You can also think of cities as declaring events. There are laws that say "when there is a green light, cars move through the intersection".

Discuss: Ask the students why they think this is an event.

Today, students will play in Play Lab, but the events they will be working on will be more like the video games they are used to playing. Events will take the form of actions, such as clicking the screen or two characters running into each other.

Display: Begin by showing Puzzle 1 to your students.

Think/Pair: Ask them to predict what will happen when the code is run, and to discuss with their neighbors. Run the code, and discuss the outcome.

Review of "Personal and Private Information"

Remind students of information that is safe to share online and information that is strictly private.

SAFE - Personal Information UNSAFE - Private Information
Your favorite food
Your opinion
(though it shoud be done respectfully)
First name
(with permission)
Mother's maiden name
Social Security number
Your date of birth
Parents' credit card information
Phone number


Discuss other examples of the two categories above.

Main Activity (30 min)

Goal: Today, students will be creating their own alien dance party! They’ll begin by reviewing how to put sprites on the screen, then they will assign them behaviors and learn to change those behaviors when an event is initiated.

Teaching Tip

Encourage students with questions/challenges to start by asking their partner. Unanswered questions can be escalated to a nearby group, who might already know the solution. Have students describe the problem that they’re seeing:

  • What is it supposed to do?
  • What does it do?
  • What does that tell you?

Transition: Move students to their machines. Encourage students to follow the instructions for each puzzle. Help them realize that this is a creative activity, intended to help them learn Sprite Lab. It is not an assessment activity of any sort.

Reminder: If puzzles are sharable, remind the students to only share their work with their close friends or family. For more information watch or show the class Pause and Think Online - Video.

Wrap Up (15 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?
  • How do you feel about today's lesson?
  • How did it feel to have control over what your characters were able to do?
  • Did you change the program in any way to make it feel more like your own?
