2. The Rules
1. Conduct yourself in a responsible manner at all times in the laboratory.
2. Follow all written and verbal instructions carefully.  If you do not understand a direction or part of a procedure, ASK YOUR TEACHER BEFORE PROCEEDING WITH THE ACTIVITY.
3. Never work alone in the laboratory.  No student may work in the science classroom without the presence of the teacher.
4. When first entering a science room, do not touch any equipment, chemicals, or other materials in the laboratory area until you are instructed to do so.
5. Perform only those experiments authorized by your teacher.  Carefully follow all instructions, both written and oral.  Unauthorized experiments are not allowed.

3. 6. Do not eat food, drink beverages, or chew gum in the laboratory
6. Do not eat food, drink beverages, or chew gum in the laboratory.  Do not use laboratory glassware as containers for food or beverages.
7. Be prepared for your work in the laboratory.  Read all procedures thoroughly before entering the laboratory.
8. Horseplay, practical jokes, and pranks are dangerous and prohibited. 
9. Observe good housekeeping practices.  Work areas should be kept clean and tidy at all times. 
10. Be alert and proceed with caution at all times in the laboratory.  Notify the teacher immediately of any unsafe conditions you observe.
11. Dispose of all waste properly.  Never put solids in sink drains.  Sinks are to be used only for water. Check with your teacher for disposal of lab materials.
12. Keep hands away from face, eyes, mouth, and body while using chemicals or lab equipment.  Wash your hands with soap and water after performing all experiments. 

4. 13. Experiments must be personally monitored at all times
13. Experiments must be personally monitored at all times.  Do not wander around the room, distract other students, startle other students, or interfere with the laboratory experiments of others.
14. Know the locations and operating procedures of all safety equipment. If there is a fire drill during a laboratory period; containers must be closed, and any electrical equipment turned off.
15. Dress properly during a laboratory activity.  Long hair, dangling jewelry, and loose or baggy clothing are a hazard in the laboratory.  Long hair must be tied back, and dangling jewelry and baggy clothing must be secured. 
16. Report any accident to the teacher immediately, no matter how trivial it seems.  Do not panic. 
17. Report any broken equipment or spills to the teacher immediately for proper clean up and disposal procedures.

5. Lab Equipment

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

7. Glass slide: provides mounting surface for examination by microscope

8. Coverslip
Covers specimens on a glass slide

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

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

11. Beaker: holds and measures liquids.

12. Funnel: transfers liquid from one place to another Filter Paper: filters liquid

13. Erlenmeyer Flask: holds, measures, and stores liquids; can be stoppered

14. Dropper: measures out drops of a liquid

15. Test tube: holds liquids

16. Test tube rack: holds test tubes

17. Test Tube Holder: holds test tubes

18. Forceps: grasps small objects

19. Metric ruler: measures length

20. Balance: measures mass

21. Thermometer: used to measure temperature

22. Stirring rod – glass rod used to stir liquids

23. Scoopula

24. Mortar and Pestle
pestle
mortar

25. Petri dish

26. Anemometer
Measures wind speed

27. Barometer
Measures air pressure

28. Rain gauge
Measures amount of precipitation/rain

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

30. 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

31. The metric system measures in units of 10
Prefix
Kilo = X10X10 or 103
Hecto = X10 or 102
Deka =
Gram/liter/meter = 1
Deci =
Centi =
Milli =

32. Examples
1 kilogram (kg) = 1000 grams (g)
.001 grams (g) = 1 milligram (mg)
100 meters (m) = 1 hectometer (hm)

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

34. Mass: measure of the matter in an object

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

36. Time
Time: interval between 2 events

37. 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

38. 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.

39. 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)
