Structure of Matter
know the structure
of the atom and know it is composed of protons, neutrons, and electrons.
5-1-b Students know all matter
is made of atoms, which may combine to form molecules.
- Structure of atoms & molecules (molecular modeling kits)
- The scale of atoms & molecules - Powers of ten
- On-line simulations of atoms & molecules
- The variety of atoms - Periodic table
- Evidence of electons - Static electricity (balloon, water stream, Van de Graaf
know that compounds are formed by combining two or more different elements,
and that compounds have properties that are different from their constituent
know all matter is made of atoms, which may combine to form molecules.
5-1-f Students know differences
in chemical and physical properties of substances are used to separate
and identify compounds.
5-1-i. Students know the common
properties of salts, such as sodium chloride (NaCl).
4-4-b. Students know how to identify
common rock-forming minerals (including quartz, calcite, feldspar, mica,
and hornblende) and ore minerals by using a table of diagnostic properites.
- Matter is made of atoms and molecules
- Chemical and physical properties of matter
- Properties of salts and minerals
know atoms and molecules
form solids by building up repeating patterns, such as the crystal structure
of NaCl or long-chain polymers.
- Videomicrsocopy of crystal formation (silver,
salt, alum, etc.)
- Polymer activity: Polymers
(Polyvinyl alcohol or white glue and sodium borate decahydrate (e.g.
Twenty Mule Team
Borax“ Laundry Booster))
know the states
of matter (solid, liquid, gas) depend on molecular motion.
5-1-g Students know properties
of solid, liquid, and gaseous substances, such as sugar (C6H12O6),
water (H2O), helium (He), oxygen (O2),
nitrogen (N2), and carbon dioxide (CO2).
- Properites of matter
- States of matter -
- Common substances
- Water (electrolysis, surface tension demonstrations)
- Oxygen (flame demonstration)
- Carbon Dioxide (fire extinguiser demonstration)
- Sugar - (Diet/regular soft drink density demonstration)
know that in solids
the atoms are closely locked in position and can only vibrate; in liquids
the atoms and molecules are more loosely connected and can collide with
and move past one another; and in gases the atoms and molecules are free
to move independently, colliding frequently.
- Model of molecular activity (BBs)
- Role play: states of matter
- Crushing can, air pressure fountain demonstrations
know how to use the periodic
table to identify elements in simple compounds.
