For my 3d molecule, I chose water as my molecule. Water is a small molecule and easy to make, as it is composed of 2 hydrogen and 1 oxygen. The scientific name for water is H2O. I chose water because it is very important to me. It is important to me because I drink water everyday and you need water in order to live. I am very thankful for having almost unlimited water, which other people don’t have. That is why water is important to me and why I made my molecule a water molecule.
