Preface

General

Scratch 2.0 (released May 9, 2013) is the second major version of Scratch to be released during the life of the product. Among other things, it features a redesigned editor and website, and allows you to edit projects directly from your web browser.

This module is one in a collection of modules designed to help beginners ofall ages (8 and up) learn how to create the code for computer programs using Scratch 2.0.Information is provided not only for the beginners themselves but also for their parents and teachers where appropriate.

The purpose of this module is to provide a high-level overview of the Scratch programming environment. Future modules will provide more detailed information about the programmingenvironment.

While this module is not intended to exclude the "older" beginners, much of the information contained in this module may be of more interest to the parentsand teachers of younger students who are wondering if they should allow the students in their charge to become involved in Scratch.

A prediction

It's probably safe to say that a large percentage of the professional athletes in the major leagues of sports are people who became involved in sportsin little league when they were quite young. It's probably also safe to say that a large percentage of successful professional musicians were eitherenrolled in serious musical instruction at an early age, or were involved as members of garage bands by their early teens.

I predict that in ten to fifteen years, computer science professionals and professionals in a variety of computer-related fields will be the people who arecurrently engaged in the little leagues of computer science .

Where are the little leagues of computer science?

One of the most important little leagues of computer science is centered in the Lifelong Kindergarten group at the MIT Media Lab . This group has developed and is supporting a programming environment forbeginners called Scratch . According to MIT,

"Scratch is a programming language that makes it easy to create your own interactive stories, animations, games, music, and art -- and shareyour 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 learnimportant mathematical and computational ideas, while also gaining a deeper understanding of the process of design."

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,

what is cell division
Aron Reply
Cell division is the process by which a single cell divides into two or more daughter cells. It is a fundamental process in all living organisms and is essential for growth, development, and reproduction. Cell division can occur through either mitosis or meiosis.
