This I Believe Speech = motivational, inspirational, believable

Monday, May 19th, 2014

The purpose of this speech is to tell others what you have done, what you have achieved – ultimately, how you were inspired to change/make changes. Your speech should ‘speak’ to the heart (pathos/emotions) of others; it should result in your audience evaluating their current lifestyles and consider what they believe they CAN change.

Here are is a speech by Steve Jobs who believed he could, therefore he did, change the world:

a. Steve Jobs – motivational speech; think about life rather than death (positive attitude)

Challenge for Week of 20 May: making inferences

Monday, May 19th, 2014

Due date: Friday, 23 May, @ 3PM









This is an excerpt from Martin Luther King Jr.’s celebrated “I Have a Dream” speech (2:10 – 3:50 in the video below)

So, even though we face the difficulties of today and tomorrow. I still have a dream. It is a dream deeply rooted in the American dream.

I have a dream that one day this nation will rise up and live out the true meaning of its creed: “We hold these truths to be self-evident: that all men are created equal.”

I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at a table of brotherhood.

I have a dream that one day even the state of Mississippi, a state, sweltering with the heat of injustice and sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice.

I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.

I have a dream today.

a. Describe King’s state of mind. Identify specific words and phrases from his speech to support your inferences.

b. What technique is used most often in this speech to engage his audience?

c. Synthesize: Dr. King was a great orator and is still considered one of the best public speakers. What do you learn from reading his speech and watching his delivery (see video below: 05:40 – end) that will help you to (i) write your “This I believe” speech and (ii) deliver your speech to a teenage audience?

Explain the 4 Laws of Ecology

Monday, May 19th, 2014

4 laws

Cycles of Matter in Nature: Second Law of Ecology – Everything must go somewhere

Sunday, May 18th, 2014

Cycles in Nature

  • Law of Conservation of Matter – Matter cannot be created nor destroyed in any chemical reaction. It can only be transformed from one form to another.
  • Cycle – A cycle shows the reusing of certain elements and compounds (e.g. water, carbon, oxygen, nitrogen, phosphorus) in different forms in ecosystems.


Learn about the Nitrogen Cycle on this interactive website. 

You will also learn much from CLASSZONE another interactive site.

Nitrogen (N) is an essential constituent of protein, DNA, RNA, and chlorophyll.
                     – N is the most abundant gas in the atmosphere, but it must be fixed or converted into a usable form.

Nitrogen Fixation

A small amount of atmospheric nitrogen is fixed by lightening. The high energy combines N and H2O resulting in ammonia (NH3) and nitrates (NO3). These forms are carried to Earth in precipitation.


  • The sun provides the heat energy required for the cycle to continue.
  • The oceans and rivers are the main reservoirs of water.
  • Evaporation – Water evaporates into the atmosphere.
  • Condensation – Water condenses into droplets in the clouds.
  • Precipitation – As the water droplets in clouds enlarge, water falls to earth in the form of rain, snow or hail.
  • Transpiration – Water is lost through the leaves of plants (‘trees perspiring’).


  • Carbon occurs in all living organisms in the forms of carbon dioxide, carbohydrates (sugars and starches), proteins and fats.
  • Oxygen occurs in all living organisms in the forms of oxygen gas, water, carbon dioxide, carbohydrates, proteins and fats.
  • Photosynthesis – Photosynthesis is the process used by plants containing chlorophyll to utilise sunlight, carbon dioxide and water to form sugar (as glucose) and oxygen.
Carbon Dioxide + Water Sunlight Glucose Sugar + Oxygen
CO2 + H2O Arrow C6H12O6 + O2
  • Respiration – Respiration is the process that most living organisms (including animals, plants, fungi and micro-organisms) use to obtain energy from glucose sugar and oxygen. The wastes formed are carbon dioxide and water.
Glucose + Oxygen Arrow Carbon Dioxide + Water + Energy
C6H12O6 + O2 Arrow CO2 + H2O + Energy
