Inferencing Observations Alka-Selzer The Iron in our Food Kool-Aid Density Bottles This is the space that an object takes up. You can measure volume using a
beaker or graduated cylinder
Volume of rectangular prisms can
be found using this formula: length x width x height Volume of irregular items can be
found using displacement Weight is measured on a scale and can
change depending on gravitational pull. The amount of matter in an object. This will never change, no matter where you go!

Mass is measured in grams on a balance. weight This is the measure of the pull
of gravity on an object. This is how much matter is is packed into a given space! SQUEEZE density = mass/volume What can you tell about a substance based on your senses?
touch? What is measurable?
weight? Inferences are guesses based on information
you already know...your OBSERVATIONS! Inferences Solids have a definite shape and volume. Their molecules are tightly packed! liquid Liquids have a definite volume
but NO definite shape! Molecules SLIDE past one another! magnetism This is matter's ability to be attracted
to a magnet! Gases do not have a definite volume or shape. Their molecules are fast moving and far apart! Without enough energy,
plasmas return to neutral gas.

Examples include... stars flourescent lights neon signs Must be at ABSOLUTE ZERO A group of atoms makes a SUPER ATOM Mystery Matter Sink/Float Some examples of plasmas include... Separating
Mixtures Milky Mixtures In a mixture, two or more substances are mixed.
The substances ALWAYS keep their original properties! Solutions are a special type of mixture...
they are HARD to take apart!

Generally, solutions are TRANSPARENT. This is a substance dissolved in another substance. Like the SALT in saltwater!
the KOOL-AID in your glass!
the CARBON DIOXIDE in Coke! A substance in which

another substance

is dissolved,

forming a solution! solvent Concentration is used to talk about how

a solution is! The opposite of CONCENTRATED is DILUTED.
To dilute a solution, just add more solvent! STRONG Where one substance is dispersed
evenly into another substance and
DISAPPEARS! is the measure of how much of one substance

can be dissolved in another substance. I hope you enjoyed...
