Talofa lava 10BN! I just wanted to let you know that although us 3 (and hubby) have gone to Samoa, I will be thinking of you. I have organised this so that you will be able to work through your work independently and together.
There are places (see below) where I will put in a checkpoint and ask you to comment on your progress. When I get to a a place with internet (?) I will check in with you.
I feel so confident in your abilities to work with diligence and show real commitment to your own learning and progress. See below the: TO DO's and CHECKPOINTS

Earth- Making of a planet
LUCKY PLANET is the name of this unit. Before you go any further I would like you to really understand why Earth is such an amazing planet and how is it that it became and now can support such complex life. Do you think such a planet exists anywhere else in the universe?
TO DO 1: (this may take two lessons)
1.Watch this video below (on the big screen or individually with headphones)
2. Complete own notes to key questions while watching.This is done on the worksheet "Earth- Power of the Plant-Rare Earth". Paste into your books please.

When I was watching this I wondered how did they even know this stuff......
10 Facts about earth- |
CHECKPOINT #1
TO DO 2: Read text below. This information bridges key point from the video and the next learning challenge. Watch the short video below too.
Earth is unique in the Solar System as being the only planet which is able to support life in all its forms: from basic living micro-organisms to highly sophisticated and intelligent human beings. There are many reasons why this happens.
Reason 1: Atmosphere Earth has a breathable atmosphere. Oxygen is the gas that is required for the life of most creatures. This is present in Earth's atmosphere and also in water. Oxygen is constantly put into the atmosphere by plants and trees. Earth's atmosphere also contains a small amount of carbon dioxide. This is a poisonous gas which makes up most of the atmosphere of planets like Venus and Mars and makes them unable to support human life. However, its smaller presence on Earth is useful as it helps to moderate the planet's temperature and is absorbed by plants during photosynthesis to produce oxygen.
Reason 2: Climate Earth has a suitable climate. This is caused by the moderate amount of carbon dioxide in the planet's atmosphere, which is constantly refreshed whenever there is a volcanic eruption. The temperature on Earth does not go from one extreme to the other either. Mercury can be anything from 200°c below freezing to 375°c above. At 375°c, water would only exist as a gas, and the planet would be completely dry. Venus has a surface temperature of 480°c, which would be much too hot for anybody to live in. Mars, although it can reach 25°c, is usually freezing and can be as cold as -140°c, a temperature which would freeze blood and water. Other planets are colder still.
Reason Three: Water Earth has water! Water is considered to be the most important chemical necessary for life. It contains the oxygen needed for life. Other liquids can contain poisonous elements. Water doesn't burn skin (like liquids containing acids do), it is drinkable, and it allows life-providing molecules to move around easily. Other moons in the Solar System, such as Europa, a moon of Jupiter, are believed to have oceans of water under its icy surface. Scientists believe that the presence of water on other objects in the solar system greatly increases the chances of life existing on them. Water on Earth is abundant and can be found in its three states of matter. It can be frozen, taking the form of ice. It can be liquid, seen in seas and oceans and lakes. It can also be a gas, seen as clouds. In the picture below, we can see water in its three states; a solid, a liquid and a gas. The blue glow at the top of the Earth is the planet's thin atmosphere.
TO DO 3: Collect the Earth sheet off your teacher and complete- past into your books.

Planet Earth- Travel Brochure
Earth is an amazing planet to visit. You are a travel agent and you are going to produce a tourism pamphlet to attract aliens to our planet. You will be working in pairs (you can choose BUT choose wisely) to complete this task. You will make a professional tourism pamphlet that outlies key Earthly information.
TO DO 4: (this may take 3-4 lessons) 1. Pick up the task instructions from your teacher. 2. Divide up the research sections between the two of you. Start your research and record in your own words relevant information and the images you plan to include. Save these in a word document in your Science folder in OneDrive. When you are ready: You will be using CANVA a professional pamphlet site. You can login with details below: My email: [email protected] Our password: 10BNscience You will need to SAVE work under the pair name ( see mine: Mrs Johns & Pipi). This will allow you to work independently and together. When I am back I will print them off.....or you can if you want to see the final product. |
Why on earth do we have volcanoes
Just for FUN. If you are bored on Friday night this is a really good watch ;o)
Earth should really be called Ocean.
We are now going to study the Earth's hydrosphere.
TO DO 5: Read text below and complete checkpoint #2.
The hydrosphere is the combined mass of water found on, under, and above the surface of a Earth. This includes water in liquid and frozen forms in groundwater, oceans, lakes and streams. Saltwater accounts for 97.5% of this amount. Fresh water accounts for only 2.5%. Of this fresh water, 68.9% is in the form of ice and permanent snow cover in the Arctic, the Antarctic, and mountain glaciers. 30.8% is in the form of fresh groundwater. Only 0.3% of the fresh water on Earth is in easily accessible lakes, reservoirs and river systems. Approximately 75% of Earth's surface, an area of some 361 million square kilometers is covered by ocean.

WHY ARE OUR OCEANS SO SO SO SO IMPORTANT?
CHECKPOINT #2 - Add your thoughts below:
We are surrounded by water. It is a beautiful living habitat. When I watched this movie below it made me fall in love with this part of our planet!
TO DO 6: During this lesson you can explore the content below individually or in peers with your headphones in please.
Hopefully you have some ideas why the ocean is important to us. So now you could watch some/all of the first video. Personally it blows my mind!!
Then move down and have a look at the info-graphic and the video below that......capture your feelings and thoughts in the final checkpoint #3.

SO WHAT HAPPENS WHEN OUR FOREVER PLASTIC ENTERS OUR OCEANS?
Oceans are silently choking on our plastic waste. Plastic and synthetic materials are the most common types of debris in our oceans and are having horrific impacts on marine wildlife and systems. As an island continent "girt by sea" marine debris is of particular importance for Australia. Creatures get entangled in plastics and drown and ingested concentrated toxins from plastics pose a threat to the health of the food chain. Plastics also transport and introduce species into new environments. Anja Taylor catches up with the CSIRO research team spearheading the Marine Debris Survey, a world first study of the plastics around our coastline.
Ok let's watch this: This is challenging but honest!

The Great pacific garbage patch
The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean discovered between 1985 and 1988. The patch extends over an indeterminate area of widely varying range depending on the degree of plastic concentration used to define the affected area.
The patch is characterized by exceptionally high relative concentrations of pelagic plastics, chemical sludge and other debris that have been trapped by the currents of the North Pacific Gyre.

CHECKPOINT #3- Add your thoughts below:
TO DO 7: Rule up a Table like below. You might like to do a full week. Collect all the plastic in your house that is disposed of. KEEP it and bring it in OR take a photo at the end of the week. How do you feel about that?
- On Monday you will bring in ALL your plastic for the week. BE BRAVE and STAND BY IT! As a class we will
- Did you find this challenge difficult? Why or why not? Explain.
- How has this challenge impacted on your thinking?
