Wed., March 22nd: Testing Physical Properties and Chemical Beginnings


CHEMICAL PROPERTIES: Properties that can be observed during or after a chemical reaction. Examples are how easily something catches fire (flammability), decomposition, reactivity with air (rust), water, how toxic it might be.


  • A change that occurs when one or more substances change into entirely new substances with different properties.
  • Substances present at the beginning of the change are NOT present at the end.
  • Cannot or are very difficult to undo!


Different signs include

  • an odor is produced
  • light or smoke is seen
  • temperature change- it takes in or gives off heat
  • production of gas bubbles
  • color change (like rusting)

Monday, March 20th: Physical Properties

a169483b830c9acd4b27591d4f27113fWhat is a physical property of a substance and what are physical changes?

A physical property is a property of a substance that does not involve a chemical change.

Examples include: shape, melting/boiling point, solubility, density, color, weight, mass, volume, state of matter, or hardness.

A physical change is a change that alters the form or appearance of a material but does not make the material into another substance.

Evidence of physical changes include: change of shape, weight, color, volume, hardness, state of matter, texture (life if you sand a piece of wood, it is still wood but smoother).
