Making Goo
Douglas and the great glob of goo!
WEEK 1: Slime
Atom - basic unit of matter. Nucleus and electrons.
Molecule - 2 or more atoms bonding. Na = sodium atom + Cl = chloride atom = NaCl (salt).
Some atoms by themselves can be extremely dangerous (think of the hydrogen bomb) but when bonded can become safe/stable.
Chemistry is the study of matter and the changes it goes through with chemical reactions.
When we mixed glue and water, there was only a physical change, a mixture. But when we add the borax/water solution, a chemical change occurs which permanently alters the molecular structure of the ingredients, making it more solid and pliable.
Challenge I!
