Preface

Scratch 2.0 (released May 9, 2013) is the second major version of Scratch to be released during the life of theproduct. 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 of all 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 teacherswhere appropriate.

The purpose of this module is to get you started programming in Scratch 2.0 .

Let's have some fun in the process of learning

Scratch was originally designed to be a good learning resource. It was also designed to help students learn to program and to have fun at the same time. After all, if you and/or your studentsare going to invest the time to learn how to write computer programs, you might as well have a little fun along the way.

I suggest that you go to the Scratch home page and the Explore page and click on a few projects to see what I mean. Just keep in mind that many of the projectsthat you will find there were written by youngsters and may or may not work as advertised.

One of my favorite Scratch projects is named Son of String Art (hopefully it is still there). You should be able to click on the little yellow shapes in the green buttons at the top of theviewing area and see your shape constructed with strings resembling the string art of the sixties.

Fully interactive operating mode

Note the use of the word interactive in the above header. What you will see when you select a Scratch project on the MIT website isn't simply a passive embedded video like you might see at YouTube or Vimeo . Instead it is a fully interactive program that allows you to control the program by clicking buttons,etc., provided of course that the program was written to be used in an interactive mode.

Viewing tip

I recommend that you open another copy of this module in a separate browser window and use the following links to easily find and view the imagesand listings while you are reading about them.

No computer setup required

I explained quite a bit about Scratch in the earlier module titled Scr0300: Scratch 2.0 Overview .

Assuming that you are able to access the Scratch website and run some of the projects, there is nothing more that you need to do toget your computer set up to create new projects in Scratch 2.0 .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
