Justinian The Great dissects a starfish.
Roberta, donning finger-less gloves -- the penultimate fashion statement of the hour -- is horrified that we dissect ANYTHING. The fact that she was expected to participate elicited a "Mooooommmmyyyy" and her mom came over and helped.
Anya was much more willing to dissect. Her poor four legged starfish. Anya learned that the starfish's stomach actually protrudes from its body to digest food. Cool and gross all at the same time.

Making 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.
