What is Scratch?
Scratch is a programming based software but the scripts snap together in Lego like blocks. It can be used to create interactive stories, animations, music, games, art and simulations. Scratch has an online community where students can share their projects. If they have access to the Internet they can become a member of the community and upload their projects, create galleries of their favourite projects, make comments about, and see the work of others.
Sharing of work is encouraged. You can download a project, create a remix and share it in your own gallery but you will find that all the contributors have been acknowledged. Sharing and improving a project is encouraged and valued. AND Scratch is free!
“Scratch is developed by the Lifelong Kindergarten group at the MIT Media Lab, with financial support from the National Science Foundation and the Intel Foundation. The software is available free of charge from http://scratch.mit.edu.”
