Preface

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. Information is provided not only for the beginners themselves but also for theirparents and teachers where appropriate.

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

Let's have some fun in the process of learning

Scratch was designed not only to be a good learning resource, it was also designed to make learning to program fun. 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 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 apassive 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.

Setup your computer to use Scratch

The first programming language that I will use to help you learn about computer programming is Scratch . (I explained quite a bit about Scratch in the earlier module titled Scr0100: Scratch Overview .) Therefore, the first thing that you need to do is to get your computer setup to run Scratch. Go to the Scratch download page (see Resources ) to download and install the free Scratch software.

I am assuming that you already know how to download and install software on your computer. I installed Scratch version 1.4 on a Windows 7 machine a few days ago.I also reinstalled Scratch on an older Windows XP machine in order to upgrade to version 1.4.Everything went smoothly with no difficulties in either case. (I haven't tried Scratch with Windows 8 as of this writing but several people on theScratch forum are reporting "no problem" with Scratch on Windows 8..)

Questions & Answers

do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?

absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
Akash Reply
it is a goid question and i want to know the answer as well
Maciej
characteristics of micro business

Do somebody tell me a best nano engineering book for beginners?
s. Reply
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
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.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
SUYASH Reply
for screen printed electrodes ?
SUYASH
What is lattice structure?
s. Reply
of graphene you mean?

I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes

what is system testing?
AMJAD
preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
AMJAD
what is system testing
AMJAD
what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
how did you get the value of 2000N.What calculations are needed to arrive at it
