2. Unit 1 – LESSON 1
“Describing Matter”

3. MATTER
everything that has mass (the amount of “matter” that makes up an object), volume (the amount of “space” an object takes up), weight (the amount of “gravity” pushing / pulling on an object) and inertia (resist change in motion)
NO!
NO!
YES!
YES!

4. METRIC SYSTEM (SI)  a standard system of measurement of matter used by all scientists based on Power of 10 increments

5. METRIC – PLACE VALUE POSITIONS: What’s beyond “milli- ” (mm/mL/mg)?
SMALLER METRIC PREFIXES:
100 = meter (m) = 1
10-1 = deci- (d) = 0.1
10-2 = centi- (c) = 0.01
10-3 = milli- (m) = 0.001
10-6 = micro- (u) =
10-9 = nano- (n) =
10-12 = pico- (p) = m d- c- m- X u- n- p-

6. METRIC – PLACE VALUE POSITIONS: What’s beyond “kilo- ” (km/kL/kg)?
LARGER METRIC PREFIXES:
100 = meter (m) = 1
101 = deca- (da) = 10
102 = hecto- (h) = 100
103 = kilo- (m) = 1,000
106 = mega- (M) = 1,000,000
109 = giga- (G) = 1,000,000,000
1012 = tera- (T) = 1,000,000,000,000 T- X G- M- k- h-
da- m

7. MASS  is the measure of an object’s RESISTANCE to MOTION and remains CONSTANT

8. MASS versus WEIGHT: DEFINITION: UNIT of MEASUREMENT: INSTRUMENT:
MASS  amount of MATTER that makes up an object
WEIGHT  amt of FORCE pushing down on an object
UNIT of MEASUREMENT:
MASS  is measured in GRAMS (g)
WEIGHT  is measured in NEWTONS (N)
INSTRUMENT:
MASS  is measured using a “centered” BALANCE
WEIGHT  is measured using a SPRING SCALE

9. MASS versus WEIGHT: (continued) CHANGING LOCATION:
MASS  will STAY the SAME on various planet location
WEIGHT  DOES CHANGE on varying planetary locations due to their different amounts of GRAVITY

10. VOLUME  is the measure of how much SPACE an object/liquid takes up

11. DENSITY  is the amount of MASS packed into a given amount of VOLUME
