Background

During the next two labs, you will create your own interactive computational media with Scratch. The ideas we learn in this programming environment translate directly to what you will be doing in Java throughout the semester. Today we will explore the concepts of objects, instructions, and sequence.

Objectives

• Express a complex activity using a sequence of instructions.

• Become familiar with object-oriented programming concepts.

• Create a Scratch project that combines animation and music.

• Understand and practice incremental development techniques.

Key Terms

Sprite

a small being, human in form, playful and having magical powers

Stage

a large platform on which people can stand and can be seen by an audience

Object

programming construct that combines code with data (e.g., a sprite or stage)
