A way of learning more about the natural world that provides possible explanations to questions and involves using a collection of skills.
Science helps us answer questions and solve problems.
Science is the process of trying to understand the world.

 Background Information: One of the most important skills in science is that of OBSERVATION.
 Most of the time we think of observation as something we do with our eyes; when we see something, we observe it.
However, all five of our senses can be used to make observations: sight, hearing, taste, touch, and smell.
 We can make two kinds of observation: those that are
FACTS, and those that are OPINIONS. Facts are those things that are true for everybody. Opinions are beliefs based on personal preference.

Procedure:
1. Close your eyes.
Keep them closed!
2. Use your sense of TOUCH to observe the object I put in you hand.
3. Write at least three sentences describing what you observed.

 4. Use your sense of HEARING as you LISTEN the object.
 5. Write at least three sentences describing what you observed.

 6. Use your sense of SIGHT to observe the object.
 7. Write at least three sentences describing what you observed.

 8. Use your sense of SMELL to observe the object.
 9. Write at least three sentences describing what you observed.

 10. Place the object in your mouth.
 Use your sense of TASTE to observe it.
 11. Write at least three sentences describing what you observed.

Sixth Grade Science Laboratory Safety Rules
• I’m Labbie, your laboratory retriever.
When you see me, it’s a friendly reminder to follow all lab rules and safety procedures.

 Scientific laboratory is a place of adventure and discovery. Some of the most important events in scientific history have happened in laboratories. The antibiotic powers of penicillin were discovered in a laboratory. Plastics used today for clothing and other products were first made in a laboratory. The list is endless.

•
One of the first things any scientist learns is that working in the laboratory can be an exciting experience. However, the laboratory can also be quite dangerous if proper safety rules are not followed at all times. In order to prepare yourself for a safe year in the laboratory, read the following safety rules. Then read them a second time. If you do not understand each rule, ask your teacher to explain any rule that is unclear.

TEST FOR ODORS
Odors from chemicals may be dangerous. To test an odor:
1. Hold the test tube
2. Keep the test tube several inches away from your nose
3. Waft (fan with your hand) the fumes coming from the test tube toward your nose.

You are the Mad Scientist. Yesterday you received this note in the mail. Now you need to reply providing the science student with the information they requested.
Dear Mad Scientist,
School starts in a few days. I am excited and nervous. I love science and can’t wait to get into science lab! Last year I got in trouble a lot for playing with the materials and making my own directions. What should I do so I don’t get in trouble this year?
Sincerely,
Curious Kate

• Measuring mass

 Expert Information: Balances are used to measure mass.
 The units of mass are grams (g) and kilograms (kg).
 The instrument you will use most often to measure mass is the triple beam balance. The triple beam balance gets its name from three long, horizontal metal bars called beams connected to a pointer on the right-hand side. The pointer should always be at
zero point before obtaining the mass of any object.
On each beam is a rider that slides across the beam.




 Slide all riders back to “0” on the beams before massing any object. Use the adjustment knob to zero out the instrument if necessary.
 Place the object to be massed on the pan. Chemicals should be placed on waxed or filter paper before massing.
 Gently slide the riders along the beams while determining mass. The pointer will swing above and below the zero point while you are adjusting the riders.
 Make sure each rider is in a notch before reading.
 The mass of the object will be the sum of the masses on all beams.
 Always return the riders to zero BEFORE removing the object from the pan.

Expert Information: A graduated cylinder is used to measure liquid volume.
The unit is the milliliter, abbreviated mL. To use a graduated cylinder, you must remember the following:
 Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus.
 The graduated cylinder will usually have heavy markings at 10, 20, 30 . . .
milliliters. There are usually smaller markings in between the larger units called
graduations. Read the graduated cylinder to the nearest tenth of a milliliter (31.5
mL or 30.0 mL).

Notice how the liquid curves up the side of the graduated cylinder.
To get the most accurate reading, read the measurement at the bottom of the curve, or meniscus.

Expert Information: A thermometer is a tool or instrument used to measure
temperature.
Thermometers should be handled with care. They are tubes of glass filled with either mercury or colored alcohol. At the bottom of the tube is a wider part called the bulb. When the bulb is heated, the liquid in the bulb expands or gets larger, causing the liquid to rise in the tube. When the bulb is cooled, the liquid contracts or gets smaller, causing the liquid to fall in the tube. The bulb at the base of the thermometer should be immersed in the material to be measured. To use a thermometer, you must remember the following:
 The thermometer does not need to be shaken down.
 If you are measuring the temperature of a material that is being heated, make sure the thermometer bulb is not resting on the bottom of the container.
 To read the temperature, your eyes should be level with the liquid in the thermometer.
 Read the temperature at the closest line to the liquid.

Expert Information: The standard unit for measurement of length in the metric system is the meter .
In science lab, most measurements are much smaller than a meter.
A metric ruler is the standard instrument for measurement in the scientific laboratory.
On a metric ruler, each individual line represents a millimeter ( mm ). The numbers on the ruler represent millimeters ( mm ). There are 10 millimeters for each centimeter.

 To read a metric ruler, each individual line represents .10 (1/10) of a centimeter,
 or 1 millimeter. Notice when converting from centimeters to millimeters,
 the decimal point is moved one place to the right.
To convert millimeters,
 to centimeters, move the decimal point one place to the left.
