2. Date: 2/17 Goal: I can use the concept of broadcasting through role play and then complete a broadcast event in Scratch.
Bell ringer: What does it mean to broadcast something (example the radio station is broadcasting music right now)? If a radio or television station is broadcasting something, does that mean that everyone is listening to it?

6. Date: 2/18 Goal: I can use the concept of broadcasting through role play and then complete a broadcast event in Scratch.
Bellringer: In the role play yesterday, Instead of using broadcast, do you think you could just use “wait _ secs” blocks? What might be an advantage to using broadcast Instead?

Bellringer: In the role play yesterday, Instead of using broadcast, do you think you could just use “wait _ secs” blocks? What might be an advantage to using broadcast Instead?
Answer:
One advantage is that if your entire program is
based on waits, if you edit something in scene 1, it
could possibly throw the timing off for the rest of the program.)

13. Date: 2/20 Goal: I can complete a broadcast event in Scratch.
Check your work against the rubric
Add motion, more dialogue, edit costumes for 5 point Extra credit
Gallery Walk and grade your peers work
Save your project on thawed drive and the file to Mr. Stoll

14. Bell ringer: Describe how you would graph in your
Date: 2/9 Goal: Explain the 3 major ways to move sprites and choose
the appropriate method of moving to make a cat circle the bases.
Bell ringer: Describe how you would graph in your
Algebra class (The x‐y coordinate plane, etc)
The “repeat” block will do whatever is inside it n
times. This behavior can be called iteration or
looping. Iteration is a construct that is used in other programming languages. There differences between the 3 ways to move. The sprites will
reinitialize themselves when the green flag is
clicked.

15. Date: 2/9 Goal: Explain the 3 major ways to move sprites and choose
the appropriate method of moving to make a cat circle the bases.
1. Go to Mr. Stoll’s Web page – Exploring Computer Science
2. Save “Moving.sb” file on your desktop
Open the file in Scratch
Follow the directions on the Moving. Sb worksheet and answer the questions on the back of the sheet
#10 open “baseball.sb”
The worksheet will be collected at the end of class

16. Date: 2/10 Goal: I can explain event driven programming and write A program that responds to user created event from the mouse and keyboard. Bell Ringer :How do the programs on the computer know what the user wants to do next? In other words, if you are surfing the web, how does the computer know what page to go to next?

Bell Ringer :How do the programs on the computer know what the user wants to do next? In other words, if you are surfing the web, how does the computer know what page to go to next? User events (clicks, typing) driving the program and causing it to respond.

Scratch provides some blocks that allow you to write
Programs that respond to user events relatively
easily.
When green flag clicked (we’ve already seen this)
When Sprite clicked
When_key pressed

19. Date: 2/10 Goal: I can explain event driven programming and write A program that responds to user created event from the mouse and Keyboard. Discuss answers to moving project

Date: 2/10 Goal: I can explain event driven programming and write
A program that responds to user created event from the mouse and
keyboard.
You will be making an alphabet learning game.
Alphabet Sample Rubric
Create the first letter in front of the class with the
Students helping you.
See “alphabet learning.sb”
Show how to create new costumes.
Students may bring in pictures from the internet. Download a .gif or .jpg.
Use import or paint to make it the second costume for your
letter.
Change costumes - Use a “switch to costume _” block.
Output in talk bubbles.
Use a “say_ for_ sec” block.
Remind students that they may pick the theme of alphabet game (animals, food, etc).

Sprites change costume when clicked on.
Sprites change costume when letter is typed on keyboard
