- students wrote Molecules requiz.
- for the next evaluation - which will happen next class - students can choose between a requiz on Elements or a first quiz on The Periodic Table or BOTH. These quizzes are small and good practice for the types of questions they'll see on a later, more valuable test.
- we reviewed Physical Changes; that they don't mess around with bonds so they don't make anything new, that they are reversible and fall under 3 types: 1) change in state, 2) change in shape or 3) are either making OR separating a mixture.
- then we took notes on Chemical changes, which are the opposite of Physical changes: they DO mess with bonds, so the make NEW things. They are NOT reversible, are associated with a display of energy and have 5 "signs".
- students were then assigned questions 1 , 2 , 6 & yes, 7! on pages 39 - 41.
- These will be checked for completion and corrected next class.
