2. Length Length is the distance from one point to another.
The SI unit for length is the meter (m).
Metric rulers and tape measures are used to measure length.
Mr. Rodesney is 1.74 meters tall. This is 174 centimeters.

3. Length
The pencil is 19.2 centimeters (cm) or 192 millimeters (mm) long.
Mr. Rodesney’s shoe is 28.0 centimeters (cm) or 280 millimeters (mm) long.
A=l×w. l = 60.2cm. w = 121.8cm.
The area of a single table is about 7, square centimeters (cm2) or square meters (m2).

4. Mass
Mass is a measure of the amount of matter in an object or substance. Weight is a measure of the force of gravity acting on a mass.
The SI unit for measuring mass is the kilogram (kg).
Balances and scales are used to measure mass.

5. Mass Masses Knight ≈ 4 grams (g) Rock ≈ 64 grams
Battery ≈ 135 grams (g)
Graduated Cylinder ≈ 26 grams (g)

6. Volume
Volume is the amount of space an object or substance takes up. Meniscus is the curve of a liquid in a container.
The SI unit for volume is the cubic meter (m3).
Liter (L), milliliter (mL), and cubic centimeter (cm3 or cc) are also used.
Beakers, graduated cylinders, and flasks are used to measure volume.

7. Volume The water in the cup was about 43 milliliters (mL).
The volume of the marble was between 2 and 3 milliliters (mL).
Final volume – initial volume = displacement volume
V=l×w×h. The volume of the tissue box was about 2,440.8 cubic centimeters (cm3).
22.6cm x 9cm x 12cm

8. Density
Density is a measure of how much mass is contained within a certain volume.
The SI unit for density is kilograms per cubic meter (kg/m3).
Which box is more dense?

9. Density Density equals mass divided volume (d=m/v)
If an object/substance has a density greater than water, it will sink.

10. Density Sample Problems 454g / 2270cm3 = 0.2 g/cm3
171g / 15cm3 = 11.4g/cm3 (Lead)
148g / 40cm3 = 3.7g/cm3 (Aluminum)
475g / 250cm3 = 1.9g/cm3 (Bone)
680g / 1000cm3 = .68g/cm3 (Gasoline)

11. Temperature
Temperature is a measure of the average energy of motion of the particles of a substance.
(How hot or cold something is)
The SI unit for temperature is the kelvin (K), but degrees Celsius (°C) is commonly used in science.
Thermometers are used to measure temperature.

12. Temperature Cold – About 1-2 deg. C.
Room Temperature – About 22 deg. C.
Hot – About 50 deg. C
We’re not going to go into this just yet. 

13. Time Time is the interval between two events.
The SI unit for time is the second (s).

14. Density Word Problems Density = Mass / Volume Mass = Density x Volume
