Some options for what people

might want to learn about IceCube:

Your great ideas/what do you want to know?:

• What neutrinos are and what they do?
• How much is CS used in the Lab?
• How the detection of a few photons can lead to finding the positions of Blazars?

Goal-setting

Are you a “coder”?

​

Reflect on your own (3 minutes):

1. What’s one thing you would like to learn about related to coding?
2. What experiences can you draw on to help you during this internship?
3. How do you think coding will relate to the rest of your life?

PROBLEM EXPLORATION

​

Your ideas!

Last week...

Variables in CodeHS.com!

Variables----things you can vary.

The definition of “Vary”:

1. Able to be different in size, amount, degree, or nature from something else of the same general class. "The houses vary in price"
• change from one condition, form, or state to another.�"your skin's moisture content varies according to climate conditions"
• introduce modifications or changes into (something) to make it different or less uniform.�"he tried to vary his diet"

​

More examples of variables

• How much memory a phone has. All phones have memory, the amount varies.
• How much salt goes into a recipe. Almost all recipes have salt, but the amount varies.
• How many doors a car has. All cars have doors, but the amount of doors varies.
• Who has an example to share?

Variables----things you can vary.

NOT things you can VERY

Means “so much” or “a lot!”

​

“I love you very much!”

A class of objects with properties that can change.

Like, variables

What inspired you to learn how to program?

“Programming seems to embody all of the principles of problem solving, which I love doing. I love the challenging feel, and when a problem is posed, I first think of how I can use algorithmic thinking to solve it.”

“My main inspiration to programing is that it is used very heavily in STEM nowadays, it will enable me to be more innovative and have a larger toolbox of skills while solving problems in college and my future career and life.”

Why is it important to match a variable name throughout a program?

“Matching a variable throughout a program can make the programs more efficient and easier to write. They need to be consistent throughout the program so that there are no errors.”

Were any of the code.org variables Boolean?

“Not yet.”

“I do not think that any of the variables were Boolean. Since Boolean variable are true or false, and that was not displayed throughout the coding exercises.”

“Yes, when I would check my code when programing tracy the turtle, I would press the button to check my code and it would either tell me that I am wrong or right which is Boolean (true or false). It checked my code using a true or flase program that would look for key things that my code needs to complete the assignment.”

​

How do you think data types or variables will affect the way that you complete your challenge?

“Having the user interact with variable could be used but I can't say for sure.”

“Yes and no, systemic changes could go wrong and it sometimes it can’t be fix immediately, which would cause problems to the program. For example when the character don’t match, and it was systematic it wouldn’t be be fixed immediately compare to a user being the one fixing it.”

“These variables and data types could definitely affect the way I complete my challenge based on the simplicity or "complicatedness" of the game/simulation I want to create. I would have my user interact with variables throughout the game.”

“Data types can be used to store data more effectively so that they can be reused and manipulated. For example, inputs given by the user should trigger pre-programmed actions, but there may be multiple actions associated with the input. Furthermore, as data changes, either by direct input or implicitly, it would be substantially more difficult without a variable to refer to them by.”

​

Variables are placeholders for data. In order for data to be stored, a variable is created by ‘declaring’ or stating what the specific data type is and the variable is then assigned a value.

Topic 2:�Loops & Recursions

You saw loops, now we’re going to learn what they’re doing in the code.

The loop is saying: do the blue commands until the condition “5” is met, then go on.

for i in range(5):

draw_square()

length = (length + 10)

​

Condition

Commands

A few other things needed for loops:

Interval

(How much to increase the count by for each cycle of the loop)

Initial condition

(what number to start the count on)

Condition

(When to stop doing the loop)

Command

(What you’re doing every loop)

Example: Brushing your teeth side-to-side for 2 minutes

for i in range(2):

move_brush(right)

move_brush(left)

Example: Brushing your teeth side-to-side for 2 minutes

Interval

(How much to increase the count by for each cycle of the loop)

Initial condition

(what number to start the count on)

Condition

(When to stop doing the loop)

Command

(What you’re doing every loop)

Start timing at 0 minutes, not at 1 minute or 45 seconds.

“i=0”

Every minute, increase the count by one minute

“i+= 1” or “i++ 1”

Go until you count 2 minutes.

“i < 2”

Command is back and forth.

“{move brush right

move brush left}”

“i” stands for “The count”

Example: Brushing your teeth side-to-side for 2 minutes

Interval i+= 1

(How much to increase the count by for each cycle of the loop)

Initial condition i=0

(what number to start the count on)

Condition i<2

(When to stop doing the loop)

Command

(What you’re doing every loop)

All together, the code is:

​

for i=0; i<2; i+= 1

{move brush right

move brush left}

“i” stands for “The count”

Example: Brushing your teeth side-to-side for 2 minutes

Interval i+= 1

(How much to increase the count by for each cycle of the loop)

Initial condition i=0

(what number to start the count on)

Condition i<2

(When to stop doing the loop)

Command

(What you’re doing every loop)

Often, the command is separated out:

​

for i=0; i<2; i+= 1 {

move brush right

move brush left

}

“i” stands for “The count”

Here’s a similar code in Java Script

​

for (var count = 0; count < 6; count++) {

draw_square();

length = (length + 10);

}

​

Here’s a similar code in Java Script

​

for (var count = 0; count < 6; count++) {

moveForward(50);

turnLeft(120);

}

​

Similar but a little different.

​

for (var count = 0; count < 3; count++) {

moveForward(50);

turnLeft(120);

}

​

We used, i+=1, “i increases by 1 each cycle.

They use, “count ++”, which means:

“the count increases positively.”

We used, i

They use, “var count” which means, “the variable count functions in the following ways”

Sometimes you might set the initial condition to something other than 0 if it makes sense

This week, work through the Module “3. Loops” and practice loops in CodeHS.com
