1. Lab Equipment

2. Microscope: makes an enlarged image of a very small object.

3. Graduated Cylinder: measures the volume of liquids and solids

4. Safety Goggles: protects eyes when using heat and chemicals

5. Beaker: holds and measures liquids.

6. Dropper: measures out drops of a liquid

7. Metric ruler: measures length

8. Balance: measures mass

9. Thermometer: used to measure temperature

10. Anemometer
Measures wind speed

11. Barometer
Measures air pressure

12. Rain gauge
Measures amount of precipitation/rain

13. The Metric System: aka SI (system international)
most commonly used system
most other countries use it
all sciences use it

14. We will use the following units of measure:
Mass = gram (g)
Volume = liter (L) for liquids or cm3, cubic centimeter (cm3) for solids
Temperature = degrees Celsius
Time = second (s)
Length = meter (m)
Density = g/cm3; 1mL = 1cm3

15. Length Length: distance between 2 points
metric rulers and meter sticks are used to measure length

16. Mass: measure of the matter in an object

17. Density
mass per unit volume of a material
found by dividing mass by volume

18. Time
Time: interval between 2 events

19. Temperature
measure of how hot or cold something is
we will use Celsius
Water: Freezing= 0 degrees Celsius, Boiling = 100 degrees Celsius
‘normal’ human body temperature = 37 degrees Celsius

20. Volume: amount of space occupied by an object
if you can measure straight sides with standard length units, you can figure volume by multiplying the outer dimensions.

21. volume can also be measured in liters. BE AWARE OF THE MENISCUS!!
Meniscus: the curvature of the surface of water.
Always read water levels at the lowest point (bottom of the meniscus)
