A vast plankton bloom occurring east of New Zealand has been captured by satellite. NASA released the picture showing the large blooms of plant-like organisms called phytoplankton.It has occurred off the east coast where cold rivers of water have branched off from the Antarctic Circumpolar Current flow north past the South Island and converge with warmer waters flowing south past the North Island.
"The surface waters of this meeting place are New Zealand's most biologically productive," Nasa says.
Phytoplankton use chlorophyll and other pigments to absorb sunlight for photosynthesis, and when they grow in large numbers they change the way the ocean surface reflects sunlight. Caught up in eddies and currents, the blooms create intricate patterns of blues and greens that spread across thousands of square kilometers of the sea surface.
In addition to their importance as the foundation of the ocean food web, phytoplankton play a key role in climate because it absorbs carbon dioxide from the atmosphere.

Introduction:
We all know that all life on Earth relies on plants harnessing the energy of the sun to make food... right?
Those two clips show some amazing but not typical ecosystems, let's look at them for interest but then get back to the more usual things we come across...

Task 1: Life in the Sea
Go have a play HERE ... to learn a bit more about marine ecosystems then..
Here is the sheet with some questions
You may work in pairs (of 3 or 4) to produce a document (or ?) with some thoughts / answers
Go to: Sciencelearn.org .... here .... for help with the answers
Don't just copy and paste, try and put things into your own words
Save your FINISHED work to a Google doc or something you can share with me (new OneDrive ?)

OMG... Oh My Gastropod : video taken with cell phone looking down microscope
Task 2: Video clips
Have a look at the following 3 clips to get an idea of what we are going to be after and how to draw them

Biology Drawings... the rules and a slideshare
example 1 https://whssscizone.wordpress.com/resources/biological-drawings/ |
What processes remove C from the atmosphere?
What processes add C to the atm?
Describe the fate of a C atom entering the ocean that:
(a) re-enters the atm
(b) ends up in medium long term storage (100's yrs)
(c) ends up in v long term storage (millions yurs)

Task 3: Cell theory
To be able to explain the role of the things you will see under the microscopes you do need an understanding of cell biology.
Work thru the following material how you want but the 2 main things you need to know about are cell membranes and chloroplasts.
For each you will need to explain what they are and what they do and relate that to things you are looking at

Task 4:
BBC Bitesize activities:
Cell membrane learning
an activity
a quick online quiz
Chloroplasts and photosynthesis quiz
Ask me about the Taiwanese fishermen and their luck
Some more useful (?) stuff....
Movement from area of high concentration to lower concentration
Semi permeable? what is this and how does it affect cells?
