Unit 1.5: Object Interaction (Scratch & Algorithm Design)
1. Learning Objectives
By the end of this unit, learners will be able to:
- Identify Objects & Behaviors: Distinguish individual objects (sprites, stage, real-world items) and analyze their unique properties, costumes, and behaviors.
- Analyze Interactivity: Evaluate how changes in one object (e.g., passing a ball, dodging an asteroid) directly impact the state or behavior of another object.
2. Questions and Answers
Q1: What is a script in scratch?
A script is a set of joined blocks of code that make one complete section of Scratch program.
Q2: What is a trigger?
Triggers tell different sprites when to run.
Q3: What is a sub-routine?
A sub-routine is a set of instructions that describes how to perform a particular task.
Q4: What are objects in scratch?
In Scratch the objects are specific sprites and stages. The sprites have different shapes and can change the way they look using costumes.
Q5: What is object interaction?
In programming an interaction is when two or more objects communicate or work together.
