Metric System
 The
metric system is the standard system of
measurement in much of the world and is also used
in the sciences in the United States.
 Mass
is measured in grams.
 Length
is measured in meters.
 Volume
is measured in liters.
 Temperature
is measured in °Celsius
+
Metric System
 Larger
and smaller units of mass, length, and volume
are calculated in units of 10 and use the same
prefixes.
Kilometer (km) 1000 meters
 Meter (m)
 Centimeter (cm) 0.01 meter
 100 cm make 1 m
 Millimeter (mm) 0.001 meter
 1000 mm make 1 m, 10 mm make 1 cm
 Micrometer (µm) 0.000001 meter
 1000 µm make 1 mm


Metric System
 Goals
for today:
 Become familiar with meters, liters, grams, and
°C.
 Practice making conversions.
+

Why is it so hard to pay attention?
 Pseudo-listening
– taking mental vacations.
 Selective
listening – getting distracted by a
wandering mind.
 Critical
listening – thinking negative thoughts
about the speaker that interfere with your ability to
follow along.
+
How can I stay focused?
 Awareness

Once you notice the problem – stop!
 Be

physically and mentally prepared to listen.
Get enough sleep.
Don’t go to class hungry.
Bring water with you.
Be aware when your mind drifts toward your troubles – try
to leave them outside the classroom.

How can I stay focused?
 Set
a goal for yourself to stay focused 100% of the
time.

It is your job to pay attention.
 Sit

Practice Listening!
 Listen
 Wait
to each sentence while I read it.
until I finish before you write anything down.
 Write
the sentence exactly as I said it.
+
Practice Listening!
 How
did you do?
 In
a real lecture, you don’t have to wait until the
speaker finishes before writing.
 Also, you
don’t take notes word-for-word.
 But, accuracy
is important! Did any of your errors
change the meaning of the sentence?
 Your
listening skills can improve dramatically with
practice.
+
Pretend to be fascinated!
Fake it ‘til you make it!
 Lean
forward in your chair.
 Follow
the speaker visually.
 Slouching
posture actually sends a message to the
brain that what you are hearing isn’t important.
Sitting up straight with attentive posture tells your
brain to pay attention!

 Study
your notes by covering
the main notes, then read the
key words or headings and go
over the things you need to
know about that subject.

Note-Taking Methods
 Outlining
method – organize material as you go.
 Charting
method- uses categories like an excel
spreadsheet.
 Mapping
 Sentence
method – great for visual learners.
method – works better than paragraphs
when you aren’t sure how all the ideas fit together.
