Scratch Syntax: Part 2 discusses variables, threads, and events in Scratch programming. Variables store values and are represented by uniquely labeled blocks. Threads are like mini-programs that can run simultaneously, started by "when" blocks. Events signal between threads, with "broadcast" blocks signaling and "when" blocks handling events. Simple games use threads and events to create levels, with an example copter game creating one level. The document concludes with homework to complete a simple game project and submit it by the due date.

1. Scratch Syntax: Part 2CMP

2. VariablesIn programming, a variable is a placeholder for some value, much like x and y are popular variables in algebra. In Scratch, variables are represented with blocks shaped like elongated circles, uniquely labeled by you.

3. ThreadsIn programming, a thread is like a mini-program within a program that can execute at the same time as other threads. In Scratch, any block whose label begins with "when" essentially demarks the start of a thread.

4. EventsAn event is a signal from one thread to another.Blocks whose labels begin with "broadcast" signal events whereas blocks whose labels begin with "when" handle events.

5. EventsAn event is a signal from one thread to another.Blocks whose labels begin with "broadcast" signal events whereas blocks whose labels begin with "when" handle events.

6. Simple GamesSimple games use threads and events to create new levels.
