Chemical compounds

Another science-related project from Marie Curie.

We worked on constructing a few chemical compounds.  We learned that most kinds of matter are made up of 2 or more different kinds of atoms joined together in a molecule.  For example, salt is a compound made from the elements sodium and chlorine.  We used World Book's Learning About Matter as a guide to construct  chemical compounds for ammonia, methane, carbon dioxide, and ethyl alcohol.

This book does a great job explaining concepts.

Activity to make chemical compounds out of clay and straws.

Ammonia

methane

carbon dioxide

ethanol/ethyl alcohol
I am glad that I found this book at the library.  It really helped to demonstrate how individual atoms work together to make chemical compounds.
