All experimental errors
Reaction in a bag EXPERIMENTAL ERRORS
hole in bag: you would not know a gas was produced
Heating Baking Soda EXPERIMENTAL ERRORS
Stopper was not secure: of the stopper is not secure it lets out gas
Hole in tubing: bottle won't fill with gas
Measuring Volume Lab EXPERIMENTAL ERRORS
sand sticks to sides of the cylinder: Volume of sand and H2O would be too low
Pour water into sand: water sits on top of sand because airspaces don't allow water to filter down
The mass of dissolved salt EXPERIMENTAL ERRORS
Not drying off cap
Outside bottle is wet during Mi
no shaking long enough
cap not on tightly
spill salt when pouring in
Melting Ice Lab EXPERIMENTAL ERRORS
Not wiping off condensation
cap was not sealed
shaking bottle
The Mass of a Gas EXPERIMENTAL ERRORS
Touch tablet after Mi
Cap is wet during Mi
Water in pan during Mi
Cap not on tight or not on quickly
Mass and Volume Lab EXPERIMENTAL ERRORS

water splashed out of graduates cylinder
Density of a Solid EXPERIMENTAL ERRORS
Measure the same side twice
Water splashed out of cylinder
Find volume of rock before mass
Paint chips off
Density of a Liquid EXPERIMENTAL ERRORS
Not rinsing out cylinder
cylinder is not re-massed empty
outside of cylinder is wet during massing
Density of a Gas Lab EXPERIMENTAL ERRORS
Make sure hand seals bottle
don't touch tablet after Mi
Put foil back for Mf
spill water when finding volume of bottle
