Jabberwocky

BY LEWIS CARROLL

’Twas brillig, and the slithy toves
      Did gyre and gimble in the wabe:
All mimsy were the borogoves,
      And the mome raths outgrabe.
“Beware the Jabberwock, my son!
      The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
      The frumious Bandersnatch!”
He took his vorpal sword in hand;
      Long time the manxome foe he sought—
So rested he by the Tumtum tree
      And stood awhile in thought.
And, as in uffish thought he stood,
      The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
      And burbled as it came!
One, two! One, two! And through and through
      The vorpal blade went snicker-snack!
He left it dead, and with its head
      He went galumphing back.
“And hast thou slain the Jabberwock?
      Come to my arms, my beamish boy!
O frabjous day! Callooh! Callay!”
      He chortled in his joy.
’Twas brillig, and the slithy toves
      Did gyre and gimble in the wabe:
All mimsy were the borogoves,
      And the mome raths outgrabe.

WebWork 101 S1 Unit 2: html tags and webpages

Lesson 1:tags and elements

LO: to learn html styles
to understand text editors and ftp clients

Warm up: {FM} What is an html tag?, an html element? give examples of each. (DoK 1)

Agenda: review w3schools.com tags, p, h1, /br
Describe use of statement.

In this unit you will learn about several important html ‘tags’. I say important because these are the few tags you need to focus on in order to build a webpage. there are many other tags you will use on occasion but these an be looked up in w3schools.com html reference if you find a need.

Lesson 1:tags, elements and attributes
changing font size, font type, font color

TAGS
comment
paragraph
break

Lesson 2:lists

lists
ul,ol, ol with styles

How text editors and ftp’s work – example: Kimodo Edit and FileZilla
Initial set up of Cloud 9 Integrated Design Environment

Lesson 3: hyperlinks

In this lesson we’ll study the role of hyperlinks, their format, attributes and some basics of web etiquette.

Part 2 of this lesson, we’ll confirm Cloud 9 IDE accounts and ftp projects. Then we’ll discuss the necessary parts of a webpage (hint: html tag, head, body, ending html tag).

Next we’ll start work on Project 1: The Jabberwocky

Chemistry Unit 10: Acids and Bases S2 Wk 2-3-4

Warm up: {FM} Describe the physical properties
(taste & texture) of acids, and of bases. Give an example of each.

Agenda: 3 theories of acids and bases

What is an acid base reaction?

Math Pre-requisite:  Venn Diagrams.

Activity: draw a Venn diagram for turtles, ninjas, and those mutant ninja turtles.

Now we discuss 3 theories of acids
Arrhenius

Draw an illustration of what happens when an acid dissolves in water.  Draw another diagram for a base dissolved in water.

 

Bronsted-Lowrey

Draw a diagram of what happens in a Bronsted- Lowry Acid-Base reaction.

How is the Bronsted-Lowry Theory different from the Arrhenius theory?

Draw a Venn diagram for the Arrhenius and Bronsted-Lowry models considering the kinds of chemicals they describe.

 

 

Lewis

Describe the Lewis Acid-Base model using diagrams and words.

 

see textbook.

Exit Assessment: draw venn diagram with the 3 theories of acids, write the definition of acid and base in each theory.

Crash course – acid-base reactions – from previous lessons

Part 2: pH and pOH

 

Warm Up: {FM} Draw the Venn diagram for 3 models of acids and bases.
What is pH? what is the pH of common household chemials.

More about pH from Crash Course…..

To learn more about exponents and the log scale please see my post “Why everyone hates John Napier” under the Math tab.

 

Here’s a simple explanation of exponential notation;

Practice problems: Exponential / Scientific notation and multiplying numbers.

 

pH and pOH

WebWork 101 Semester 1 Unit 1

Lesson 1:

Lesson 2:

3 essential inventions
1] the base
hyper text transfer protocol http://

2] the domain
mydomin
{sub domain: me.mydomain }

3] the extension
.com(mercial)
.info(rmation)
.mil(itary)
.gov(ernmemnt)
.org(anization)
.edu(cation)

Later, with the growing popularity of mobil devices
.mob(ile)

2012 the registry offered personalized extensions for sale for $176,000.00 each (geek joke: the speed of light is 176,000 miles per second).

2015 many new extensions are available such as .photo and many more.

The master registry – somewhere in Europe – keeps track of domain names and who owns them.

Part 1:

3 main types of website code;
html / css
CMS content management systems or blogs
php Programmable Hypertext Preprocessor – generates html code

other important codes; css, javascript, sql

Investigate these websites, use ‘control u’to view code;

balanced-concepts.com this is a static html site
identify, html declaration, head, body, navigation bar

wolfas.org a WordPress blog
identify theme

clothes shopping site
xxxxxx
this is an e-commerce site written in php
how can you recognize php generated htmkl code?

online tools

w3schools.org

Let’s have some fun!
