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
°CelsiusSlide4
Metric System
Larger and smaller units of mass, length, and volume are calculated in units of 10 and use the same prefixes.Kilo
meter (km) 1000 metersMeter (m) Centi
meter (cm) 0.01 meter 100 cm make 1 m
Milli
meter (mm) 0.001 meter
1000 mm make 1 m, 10 mm make 1 cm
Micro
meter (
µm) 0.000001 meter
1000
µm
make 1 mmSlide5
Metric System
Goals for today: Become familiar with meters, liters, grams, and °C.
Practice making conversions.Slide6

Metric Scavenger Hunt
Teams will search for cards and solve the problems on the cards.Check your answer with an instructor.Go find another card.
The team that solves the most problems wins!

ListeningSlide12
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.Slide13
How can I stay focused?
Awareness is key!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.Slide14
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 front and center!See better
Hear betterFewer distractions
Easier to participateHarder to fall asleepSlide15
Practice Listening!
Listen to each sentence while I read it.Wait until I finish before you write anything down.Write the sentence
exactly as I said it.Slide16
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.Slide17
Pretend to be fascinated!
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!
Fake it ‘til you make it!Slide18

NotetakingSlide19
Why take notes?
Notes give you a good study tool.Instructors often tell you what questions to expect on the exam – write them down!!!Taking notes keeps you focused.Slide20
Come to Class Prepared
Before lecture, review your notes from the previous lecture. Preview the chapter you will be discussing in lecture.At least look through the headings of the chapter, check out the figures, read the summary.
10-30 minutesSlide21
Taking Good Notes
When in doubt, write it down!Go on a diet! Your notes that is.Don’t write every word.
Use abbreviations – decide on abbreviations ahead of time. Keep a list of abbreviations.
Know your instructor.Have instructor look at your notes.Slide22
Taking Good Notes
Type or rewrite your notes after class. Can be useful if your notes are barely legible, have many gaps, or are very disorganized.Use a good note-taking system.Slide23
Cornell Note-Taking System
Draw lines to make a wide left margin and a bottom margin.In class, only use the large area for your notes.
Later, add key words to the left and a summary at the bottom.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. Slide24

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