We looked at the carbon footprint of a cheeseburger. We looked at all the components to make a cheeseburger, including all the farms to grow wheat to make flour and then bread as well as tomato and lettuces to make salad. Then, of course, we had cows to make milk for cheese and finally for the meat. Producing and transporting all of these contributes to an estimated 10 lbs CO2 released into the atmosphere for every cheeseburger we eat.
On Friday the 13th May some people from Lochaber Environmental Group are coming to school. We plan to start building our plastic bottle greenhouse, but we still need more bottles.
If you have any 1.5 or 2 liter plastic bottles PLEASE send then in to school before Friday.....
We simulated an oil spill and looked at ways to clean the mess up! Oil spills are one of the worst environmental accidents caused by man, and can have devastating effects on many animals, including birds and fish. Cleanup is extremely difficult and may take weeks or even months to complete.
With the help of a little olive oil, we simulated an oil spill and tried different options to clean it up. Options ranged from cotton buds to rice, and some worked better than others! We soon discovered that the best way to clean was to keep the oil at the surface and avoid stirring the water too much. Cotton buds and polystyrene socks worked well, as did a rice filter devised to trap the oil.
We looked at pollution the air and in the water. To show what happens when vehicles continue to pump out gases into the atmosphere we created smog in a bottle. Using a match to represent the fumes from exaust pipes, we soon had a very dark and very smelly cloud in a jar, while another jar had a beautifully clear cloud (and not smelly!).
The problem is that all this pollution will eventually end up in the water. So, we also looked at ways to clean water, including a sand filter. This was made with a bottle to serve as a funnel, and then add a layer of pebbles, a layer of course sand and then a layer of fine sand. Running dirty water through this filter is actually very effective at cleaning the water.
We ended by making a pollution catcher, which is nothing more than a paper plate covered in Vaseline. However, this simple "device" is very good at catching all the dirt in the air that WA may not see... But it's there!
