Chemistry Fundamentals
1. Read the periodic table to determine the protons, electrons and neutrons of an atom
2. Read chemical equations and identify how the molecules are made and how many atoms there are in the products (and reactants).
3. Link your understanding of the point above (2) to the theory of conservation of mass. This means that mass is neither created or destroyed in a chemical reaction.
4. Balance chemical equations
5. Identify when chemical reactions have occured, and identify corrosion, photosyntheis, and respiration reactions.
Chemical Reactions: Photosynthesis
1. Know the purpose of photosynthesis, its products and reactants (in words not the formula)
2. Know the site of where photosynthesis occurs in the leaf (cell and organelle)
3. Know why photosynthesis is important for the ecosystem

Photosynthesis Overview
1. Get an overview of how photosynthesis occurs within most leaves. Look over the two links below:
Photosynthesis video
BBC Bitesize (notes and interactive)
2. Now you've watched that, take a quick mini-quiz to see what you know!

EXTENSION (Monday)
1.Get a more detailed idea about photosynthesis:
Photosynthesis Overview: Bozeman Photosynthesis
2. Learn about florescence: When plants receive too much light they fluoresce. Human eyes can't see this (like we can't see UV or infrared) but we can see it from space using special equipment. Generally speaking, the more fluorescence the more photosynthesis is occurring.
NASA: flourescence from space
Watch the photosynthesis from space time lapse
Photosynthesis from Space Time-Lapse
Watch it through a few times to grasp what is going on.
Remember there are two things to watch: Carbon adsorption (photosynthesis) on land and in the ocean.
Notice how the great mountain ridges of the Himalayas and South American andes are consistently lighter in colour: why would this be?
Why would areas of Northern Australia, Northern Africa and Northern Asia appear black?
