We have all heard of them but not about their characteristics. I hope we see more about this elements because now i’m more informed about them and i will find them easier to classify and identify them. MYRNA  For this investigations i discover to many tools to make this blog/ web site. We investigate to about the tree elements we choose and we have to much fun investigate them. I'm more informed about this and i want to learn more about it ANA MARCELA during this third stage, i learned about the elements of copper, iron, and aluminium, these elements are very important and...
