What keeps coffee hot longer - a ceramic mug, a styrafoam cup, or those cardboard ones with the plastic lining?

If you have birds nearby, you can put a feeder in you backyard, bedroom window, a place where they will not be disturbed, and observe and keep a journal of the interactions between different species or between individuals of the same species or both, if you don't have a way of identifying the species, you can simply say Sp. A, B, C etc. but if you have acces to a book about birds species in the area, then that would be much better. Good luck!

Try this we the world does burn a lot of things and that produces CO2 . Look at it C is 1 atom to 2 atoms of Oxygen . So why is it that the percent of oxygen has not decreased?? Is it that the plants is doing a great job . Every time I have measured oxygen it has always been 20.9%
