Have you seen our photosynthesis essay?
Big thanks to all who have contributed. Not to late to add your bit. It could do with some more images and color.

General cells;
Cell Size and Shape 106,
Plant cells 108,
Identifying structures in a plant cell 110,
Animal cells 111,

Membranes and transport;
The structure of membranes 118,
The role of membranes in cells 120,
Passive transport processes 121,
Ion Pumps 124,
Exocytosis and endocytosis 125,
Active and passive transport summary 126,

Surface area to volume ratio experiment
One reason that cells are small is: Small objects have a larger surface area compared to their volume than large objects. This means that the transport of materials into and out of cells can occur easily through simple diffusion rather than requiring the more energy costly active transport.
We investigated this using some cubes cut from agar gel that had an indicator added to it. By placing the agar blocks into Sodium Hydroxide solution the bright pink colour of the agar blocks showed us how far the Sodium Hydroxide had diffused.

Science (ICAS) 2013 Competition
ICAS in Science is a is a skills based Science Literacy assessment that is completed by over a million students from over 6,300 schools in Australia and New Zealand annually. Why should you enter?
Students sit the assessment on the 5th June, however if you want to enter you need to hand in permission slip with $8.50 to the resource centre by Friday 3rd May

- Fun and challenging competition
- Great for CV
- Gives you an indication of skill on a national level
- HVHS students have traditionally preformed very well.
- All students can participate - Y9 to Y13

Bozeman Biology - Photo.........synthesis
In this clip you can see more about the two phases of photosynthesis.
Photo (light dependent stage)
and synthesis (also known as the Calvin Cycle, Carbon Fixation or Light Independent stage).
In the first stage inputs are LIGHT, WATER and require CHLOROPHYLL and ADP, the result is ADP (Adenine DI-phosphate) is 'charged' to ATP (Adenine TRI-phosphate) and water is split into oxygen and hydrogen.
The second stage requires HYDROGEN generated from 1st stage and CARBON DIOXIDE and these are used to synthesis or make GLUCOSE using the energy currency of ATP also made in 1st stage.
