Ways to teach computing concepts in Scratch

Loops

2d animation with a sprite that has more than 1 costume - see http://ice-web.cc.gatech.edu/dl/?q=node/197
Slide show with pictures that change every so many seconds - have students use their own pictures

Variables

adding a score to the pong game example and making the ball go faster by adding a speed (see http://ice-web.cc.gatech.edu/dl/?q=node/624)
creating a project that asks the user for input and calculates some result like individual cost for a group meal with tip calculated as well

Using broadcast and receive (abstraction and message passing between sprites)

adding winning or losing to the pong game (see http://ice-web.cc.gatech.edu/dl/?q=node/624)

Lists

Creating a fortune teller and pick a random fortune from a list each time the user clicks on the fortune teller
Create a magic 8 ball and pick a random response from a list
Madlibs (see http://ice-web.cc.gatech.edu/dl/?q=node/666)
Do a memory game where the computer picks a pattern and the user must duplicate it. After each round the pattern gets longer.
Create a simple musical instrument and use a list to record what was clicked (and maybe another list for timing) so that it can be "recorded" and played back.

Conditionals

Any game where you use conditionals to test if the user won or lost (see http://ice-web.cc.gatech.edu/dl/?q=node/624)
Create a quiz game where the user has to answer questions. See http://nebomusic.net/scratch.html
Create a rock, paper, and scissors game and let the user pick from rock, paper, and scissors and have the computer pick a random item. Use conditionals to tell the user who won and why.
Create an interactive story or animation where the user makes a choice and the story or animation is different based on the response.
