Were you surprised at all of the components and energy needed

to make burgers?

Much of the ingredients rely on carbon which can be wasted into the atmosphere.All this waste was just to produce burgers, think about what the waste will be on a bigger scale!!

Why is carbon important?Carbon is the basis of all organic molecules.  It makes up our genetic material (DNA and RNA) and proteins, which are essential for life.  Carbon is so special because of its ability to bond to almost any other molecule.  The major element within our bodies is carbon.

Why can high levels of carbon dioxide be bad?

Lets have a volunteer…..

• List the ways that we could reduce our carbon foot print

Green Schools

• NEW SCHOOL buildings will only receive government funding if they are designed to produce no carbon footprint.

• The experiment, which would promote designs with wind turbines, solar panels and low-energy lightbulbs, could lead to 2,000 carbon neutral schools and a reduction of 8 million tonnes of carbon dioxide.

• With schools contributing around 15 per cent of the public sector's carbon footprint, the Government has been keen to make sustainability central to the BSF programme.

How green is Skinners’ School?

In pairs think about the school that we are in and they ways that it is good to the environment and the ways that it is bad to the environment
