Density- Intro To Matter (8th Grade)
Introduction to Matter
- Describe the difference between an object's mass (measure of matter) and an object's weight (measure of gravity).
- Identify that as an object's mass increases, its weight will also increase (and vice versa).
- Identify that density is a ratio of mass to volume by measuring the mass and volumes of various materials and calculating density.
- Manipulate the density equation in order to solve for density, mass and volume (when given the other two).
- Defend the claim that the densities of substances will not change if the amount of the sample changes.

The Atom (8th Grade)
|
Identify that atoms are the smallest unit of all matter and each atom consists of protons, neutrons, and electrons.
Identify the location of the nucleus and electrons and determine which subatomic particles belong in each location.
Determine the number of protons, neutrons, and electrons of common elements based on information on the Periodic Table of Elements. (Middle schoolers study stable atoms)
-Create models of atoms in order to identify the number and location of their protons, neutrons, and electrons.

ATOMIC NUMBER = # of PROTONS 6
ATOMIC NUMBER = # of ELECTRONS 6
12.00 - 6 = 6
ATOMIC
MASS(ROUNDED) - ATOMIC NUMBER= # of NEUTRONS
PRACTICE
ATOMIC NUMBER = # of PROTONS
ATOMIC NUMBER = # of ELECTRONS
ATOMIC
MASS(ROUNDED) - ATOMIC NUMBER= # of NEUTRONS
