Lesson:
SLANT: Conservation of Mass
Mass is conserved during any physical or chemical change
this assumes the change occurs in a closed system
matter cannot enter or leave
all the same particles are present
only the arrangement, location, or motion of the particles can change.
Did our experiment obey this law?
Yes - evidence?
No - Why?

Collect
pass out corrected lesson outline worksheets
review and discuss
Slant: physical changes to matter
physical change: any change which alters the form or appearance of matter but does not change its identity
changes in
size or shape
temperature
shape
state
changes in state occur when thermal energy is added or taken away
melting/freezing
boiling/condensation
sublimation/deposition
dissolving is a physical change
a sample of matter with breaks up into its individual particles and mixes evenly with another substance
mass is always conserved during physical changes

Grade 7 agenda:
Do Now:
copy homework into your agenda.
SLANT: Density Notes
Homework:
Complete on a new sheet of paper.
put a full, formal heading at the top of the sheet.
Do the “odd” number problems only.
Neatness counts as part of your grade.
Lesson:
slant: density
density: a ratio between the mass of a sample of matter and its volume
also a way to think of how tightly matter is packed into a sample
demonstration
density is calculated by dividing mass by volume
mass is measured in grams
volume may be measured in mL or cm3
solving a density problem in FDSS format
One step problem
two step problem
time to work on data tables/assistance with reprogramming
(HW Check and pass back old papers.)
