These puzzles will help you learn more about interactivity in SCRATCH. You will need to apply what you have learned so far and become familiar with SENSING blocks AND some of the more advance concepts in Scratch.
1. Before you dive into the first puzzle, lets learn a bit more about Controls and Conditionals. Watch these videos:
2. Create you own project to solve this first puzzle and share the project to the MES INTERACTION PUZZLES STUDIO
Whenever you press the B key, the sprite gets a little bigger. Whenever you press the S key, the sprite gets a little smaller.
Scratch's coordinate system uses 2 coordinates, "X position" and "Y position", to determine the location of a sprite on the stage. The "X position" value determines the horizontal location of the sprite and the "Y position" value determines the vertical location or height. The screen is a 480x360 rectangle, such that: the X position can range from 240 to -240, where 240 is the rightmost a sprite can be and -240 is the leftmost, and the Y position can range from 180 to -180, where 180 is the highest it can be and -180 is the lowest it can be.
Play the interactive below to teach you about the X and Y coordinates on the SCRATCH stage.
4. To solve this next puzzle you may need a little more information about the SENSING blocks and the OPERATORS. Watch the videos below:
5. You are ready to tackle the next puzzle--Whenever the sprite is on the top 25% of the screen, it says "I like it up here." Create your own project to solve and share the project to the MES INTERACTION PUZZLES STUDIO
