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 available free of charge, and is currently available for Mac OSX and Windows.
at least 120 megabytes of free space to install Scratch (see note below)
The CPU speed and memory requirements have soft limits. Most computers have enough memory to run Scratch. Older computers may run Scratch slowly, but it will run.
To take advantage of sound ouput and input, you need speakers (or headphones) and a microphone. Many laptops have speakers and microphones built in.
Note: Scratch comes with a large media library and a collection of Sample projects. If you have very limited disk space, you can delete the “Media” and “Projects” folders from the Scratch folder.
Scratch is developed by the Lifelong Kindergarten group at the MIT Media Lab, in collaboration with the UCLA Graduate School of Education and Information Studies, with financial support from the National Science Foundation, Intel Foundation, and MIT Media Lab research consortia.
The Scratch project is based upon research supported by the National Science Foundation under grant number 0325828. Any opinions, findings, and conclusions or recommendations expressed on this site are those of the authors and do not necessarily reflect the views of the National Science Foundation.
