et your "CrabPower" and "OceanCurrent" variables, then press the "G" key (stands for "GoCrabby") to see where Crabby ends up. Where Crabby ends up depends on what he's trying to do and what the ocean current is doing. Your challenge is to figure out the mathematical relationship between "CrabPower" and "OceanCurrent" In other words, how do "CrabPower" and "OceanCurrent" determine Crabby's location?
The xy-coordinate grid backdrop that I used for the title screen is supplied with Scratch. I originally created programs like these back in the 80's and 90's using Logo, LogoWriter, and MicroWorlds. It is very exciting that their decendent, Scratch, is free and online! Thanks to everyone who worked to create all these wonderful programming languages that make computer programming accessible to kids.
