The Continental Congress. 1  In the First Continental Congress, Patrick Henry, a delegate from Virginia, made the bold statement that I am not a Virginian, I am an American. 2  At the time of the congress, there were around 2.5 million people living in the United States.
Next Question. The main ingredient in eggshells is calcium carbonate (the same brittle white stuff that chalk, limestone, cave stalactites, sea shells, coral, and pearls are made of). The shell itself is about 95% CaCO 3 (which is also the main ingredient in sea shells).
Our project is on how much weight can eggs hold. So we first researched the common egg itself. The most important part of an egg is the germ. You can also call it the nucleus. Next is the shell. The shell is made out of two layers. One of the layers is called the mammilary layer.
