What You Should Know…
What you should already know!
Before beginning the activities in this Learning Launcher, you should
already
be familiar with basic programming in Scratch. You should: Be familiar with the Scratch workspace and how to use its basic programming tools Be able to create a simple animation using the Sprites, Palettes, and Blocks provided by Scratch Know where to find Scratch resources online If you are unfamiliar with these concepts, you may want to consider doing the Level 1 –
Computer Programming and Animation
Learning Launcher first.
What You Should Know… The History of Greeting Cards
We ’ ve all given and received many greeting cards – birthday cards, holiday cards, thank-you cards. The average American receives 20 greeting cards each year. In fact, Americans buy over
7 billion
greeting cards annually (and that doesn ’ t even include e-cards)!!
The custom of sending greeting cards goes back to ancient Chinese New Year traditions and to ancient Egypt. By the early 15 th century, Europeans were exchanging greeting cards made from handmade paper.
In the mid-19 th century, advances in printing and paper production technology made greeting cards much more affordable. And with the introduction of the postage stamp in 1840, the practice of sending greeting cards grew quickly!

What You Should Know… The History of Greeting Cards
Lewis Prang, a German immigrant, is generally credited with starting the American greeting card industry when he began printing and selling Christmas cards in the1870 ’ s.
Today there are more than 3,000 greeting card publishers in the United States, ranging from small family businesses to large publishing corporations, and greeting cards are sold in approximately 100,000 retail stores!
E-Cards represent the fastest growing segment of the greeting card industry with over 500,000 e-cards sent annually worldwide.

Scratch Review
In the Level 1 Learning Launcher – Computer Programming and Animation, we watched several short video tutorials to learn the programming skills necessary to give characters a setting, program character interactions, and add music to the scene.

s Your Birthday!!
Let ’ s explore how to create a simple animated birthday card using Scratch!
First, let ’ s decide the features of the card, then let ’ s use the software to make it.
In this example, we ’ ll make a humorous birthday card. Let Also, let the duck say, “ ’ s have a duck quack as it crosses the stage. Duck! It ’ s your birthday ” .
Let ’ s also add a background for the stage.
Duck! It
’
s your birthday.

The top set of blocks controls the behavior of the duck and the sounds.
The bottom set of blocks controls text bubble.

A Closer Look
Let ’ s examine each set of blocks carefully. Examining the work of others will help you to solve similar challenges.
This stack of blocks has two parts. The first part tells the Sprite to play the sound called, “ Duck ” and move 5 steps. The second part of the stack tells the Sprite what to do when it hits the edge of the stage. In this case, the Sprite stops all behaviors.
To get the computer to make the sound,
“
quack
”
for the duck, open the sound tab and select the Import button.

The bottom stack of blocks is much more simple. It assigns the words that appear in the text bubble

Importing Images
As you get more creative with Scratch projects like animations, games and greeting cards, you ’ ll probably want to use your own characters for Sprites or your own pictures for stage backdrops. You may also want to record or import your own sounds, like your voice, music or sound effects.

We covered the next two slides in Level 1, but it ’ s worth taking another look!
Remember that almost EVERY program goes through a debugging process! Take your time and try not to get too frustrated. The answer is
always
somewhere right in front of you!!
What You Should Know… Programs only do what they
’
re told
“
It didn
’
t work!!
” You ’ ll find yourself saying that a lot as you work with Scratch (or, for that matter, any other method of computer programming).
That ’ s because computer programs are rather “ simple minded ” ; they do exactly what they ’ re told – no more, no less. They don ’ t know what you
want
your program to do, they can only perform each instruction literally and in the exact order given.
When creating a program with a complex set of instructions, you are bound to miss an important step or have something in the wrong order. When this happens (and it will), you need to
debug
your program. The most important element of the debugging process is always the same:
Don
’
t get discouraged, you can fix this!!
SmartLabs are all about problem-solving, so approach it like a puzzle and have some fun!!
What You Should Know… Debugging Your Program
Here are some important things to keep in mind: You ’ re not alone! Virtually every computer program must be debugged. In fact, software companies often continue debugging for years after software is released to the public! Your program
IS
working; it ’ s performing each step exactly as instructed, it ’ s just not doing what you expected! So all you need to do is find the instruction that ’ s causing the unexpected behavior. Most of the time the problem comes down to something simple. A problem with a single instruction can often lead to dramatically unexpected behavior.
First, think about
how
the program is behaving unexpectedly – often that will be your best clue to the problem. Second, carefully examine each program step in order to identify the problem instruction(s).
If you have multiple program modules, try playing each one separately to see if that helps you find the problem.
Don
’
t give up! With Scratch everything you need to solve the problem is right in front of you!
