Numbers in BinaryL.O. to be able create numbers in

binary and convert numbers in binary into decimal.

Usually, when you count, you go (first ten):

__________________________________________What happens after 9 in decimal? Or 99? Or 999?This is called the decimal number system, there are ten digits, and then a new place value is formed as they repeat.In binary, there are only two digits, how do you count them?

Decimal Binary Decimal Binary

InternetL.O. Learn how internet search results are generated and ranked.

What is your preferred search engine? _______________________________________

How often do you search for things on the internet? (check one)

Once / Day

Couple times / Week

Once / Week

Less

Have you ever wondered why the internet gives you the results it does?

Run a web search on a country of your choice. Write your choice here: _____________

A website is selected based on three signal types: Site-Level Signals, Page-Level Signals, and Off-Site Signals.

Site-Level signals include how trustworthy a site is. Click on your first result, how trustworthy does it look to you? Why?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Page-Level signals are about the classification of the site. Each web browser has indexed the web differently. If you could describe your number one result using three words, what you pick? (For example: country name, government, geography)__________________________________________________________________________________________________________________________________________________________________________________________________________________Off-Site signals refer to how trustworthy the sites are that your result links to. Are there any links on your site that lead to another website (ie. Wikipedia)? How trustworthy do they appear?____________________________________________________________________________________________________________________________________________How do you expect your answers to the above questions to be different if you selected a result from the fifth page of results?

Better SearchingL.O. learning to focus search parameters to obtain better search results.

There are many tips and tricks that can be employed when searching the web if you are looking very particular results.Search for ‘jaguar top speed’. What are you expecting to find? _____________________What did your search find? Was it what you were expecting?

______________________________________________________________________Now try searching for ‘jaguar top speed –car’. What are the websites you got this time about? What do you think it means to include ‘-word’ in your search?__________________________________________________________________________________________________________________________________________________________________________________________________________________However, notation is important when searching, if a hyphen is connected two words rather than one, it will only return webpages where those two words are used next to each other.When you look things up, the internet uses you words as key terms, it will also look up synonyms of your words. For instance, if I look for killer whales, my search results will give me orcas. If you put quotes around your search terms, it will look up those words specifically (it’s great for looking up songs you don’t remember the name of!). Give it a try! Did you get the song you were expecting?Lyrics used: ____________________________________________________________Song returned: __________________________________________________________Using two periods between to numbers with no spaces (..) searches the internet for anything that occurs within that range. What do you expect to see if you type in 1914..1918?______________________________________________________________________Give two examples of things you found other than what you expected to see:______________________________________________________________________You can use an asterisk (*) and the internet will return anything that matches. Use with quotes to find variations of common phrases, for example, “a * saved is a * earned”.Last but not least, type in: do a barrel roll.

Boolean LogicL.O. to understand the basics of Boolean logic and complete a truth table.

Boolean logic is the basis of most programs. The basic operators of Boolean logic are: “AND”, “OR”, and “NOT”.They start with a statement that is either true or false and build upon that.Example:

P = It is daytime. True False

What would NOT(P) mean? ________________________________________________

Q = It is raining.True False

What would NOT(Q) mean? ________________________________________________A truth table shows various combinations of these statements.In a table with only one statement, that statement is either true of false.

P NOT(P)

In an OR table, if at least one statement is true, then P OR Q is true as well. In an AND table, both statements have to be true.

P Q P OR Q P Q P AND Q

T F

Try These!Fill in the following truth tables. L = The lights are off.

L NOT(L)

What does NOT(L) mean?________________________________________

R = Someone is snoring.N = It is night time.

R N R AND N

Z = There is lightning.Q = It is raining.

Z Q Z OR QG = I am playing video games.X = I own an Xbox.

G X G AND X

C = I am writing in pencil.E = I am writing in pen.

C E C OR EM = Cows moo.

Coding in ScratchL.O. Utilize Scratch to create an animation.

Scratch is a web-based, visual introduction to coding that can be used to create animations and tell stories.

http://scratch.mit.edu

Click on create at the top of the page. It will take you to a page where you can begin creating. The default sprite is a cat but it can be changed as easily as the background.The “Scripts” tab is where all of the coding controls are located.Command List Sample

Experiment, try and make a sprite dance.Make your sprite walk 20 steps, play a drum, and rotate 180 degrees.

21

Select various types of commands

Causes sprite to take 10 steps, number of steps can be changed.

_____________________________

_____________________________

Changes sprites horizontal position by 10. The distances changed can be altered.

The sprite, background, and the sprite’s appearance can be changed too!

Be sure to try out all the commands!

Date: _____________________________________

Write out the code you used to do this and the colours of each command:

______________________________________________________________________

______________________________________________________________________

______________________________________________________________________

ControlsControls in Scratch allow you to control how often, or under what conditions, things happen. For example, you can have your sprite repeat an action a certain number of times.

What will this snippet of code do when run?________________________________________________________________________________________________________________________________________________________________________

22

__________________________________________________________________

__________________________________________________________________

if-then statement: If the condition in the <_> it performs the enclosed actions, otherwise it skips that segment and continues with what is below.

if-else statement: If the condition in the <_> it performs the enclosed actions, otherwise it performs the actions enclosed in the “else” section before continuing with the code..

Currently set to stop all action on the screen, can be changed to only stop a particular sprite.

Date: _____________________________________

What will this code do?____________________________________________________________________________________________________________________________________________________________________________________________________

VariablesJust like math, computer codes have variables, things that can change value depending on the circumstances. They can be used to vary how long different loops run for. Follow these steps to incorporate variables into your code:

1. Click on the orange “Data” tab and click on “Make a Variable”.

2. Name your variable. Variables are generally given names representative of their functions; for example, a variable whose value is gained by adding two numbers together may be called sum.

3. In codes, variables must be given an initial value. Generally, this is zero, but you can chose something else for your variables. This should go at the beginning of your code.

4. Using the green “Operators” tab, you can use variables to create conditions for loops to abide by.

5. To ensure your loops do not run indefinitely, make your variable changes in value every time your loop runs.

Experiment using variables in your codes.What will this code do when run?______________________________________________
