A Microworld is a term coined at the MIT Media Lab Learning and Common Sense Group . It means, literally, a tiny world inside which a student can explore alternatives, test hypotheses, and discover facts that are true about that world. It differs from a simulation in that the student is encouraged to think about it as a "real" world, and not simply as a simulation of another world (for example, the one in which we physically move about in).
microworlds is a fun experience for everyone who loves to make animations. There are many cool commands to create new projects. In a personal experience i made a bunch of turtles and the command was pd forward 5 wait 1 for all 10 turtles. Have fun in microworlds!!! Kate A.(6/7 B)

Microworlds is very easy to use, once you've gotten the hang of it. You can make your character (turtle) dance, bounce, and go insane! Some combinations are pd seth 270 fd 20, which is making a straight line going directly left on the screen, pd fd 75 rt 90 [repeat 4] will give you a square. You can basically do anything on microworlds! It's great!

Starlogo is a programming language/modeling tool/microworld construction tool developed at the MIT Media Lab by Mitchel Resnick , and is described in his book, "Turtles, Termites, and Traffic Jams: An Exploration in Massively Parallel Microworlds" . Through the language a student can populate a world with large numbers of autonomous "creatures", each given a set of simply rules to follow. The creatures are then set loose to interact with each other, leading to complex and fascinating emergent behavior.

Scratch is a new programming language that makes it easy to create your own interactive stories, animations, games, music, and art -- and share your
Scratch Cat
creations on the web. Scratch is designed to help young people (ages 8 and up) develop 21st century learning skills. As they create Scratch projects, young people learn important mathematical and computational ideas, while also gaining a deeper understanding of the process of design.

Scratch is a easy version of microworlds it uses a system that you make a comand by building blocks. The big difference is that microworlds uses a turtle you have to type in comands wich makes it more complacated I personaly like micro worlds because if you want more compacated things its in that sence easier.-Nadav B. 6/7 Y

Scratch I love it i wish it would stay forever this is a great experience for everybody. -arielleg 6/7B
