11. Learning to Read First Grade
AaBb
Learning to Read
Naming weird little squiggles. (now even Greek!)
Differentiate between a b from a d from a p.
Sounds for each letter even though some letters have multiple sounds, and multiple letters have the same sound (capitals)

12. Learning to Read First Grade
Then one day ….
Your world Changed!!

13. If this course works, you will become aware of a whole world you never noticed before.
There are times when you will have to memorize what symbols mean.
There will be times when you will confuse things that seem as much alike as b, d, and p once did.
And there will be times when you will look at a combination of events and equations in total frustration.
So, welcome to one of the most challenging (and rewarding) courses you have ever taken in your life. If you work at it and let it happen, this experience will change your world view forever.

14. Systems of Measurement Measurements
The two dominant systems are the U.S. customary system, and the metric system
Thomas Jefferson advocated that the United States adopt the metric system, but his advice was not taken. It is used, however, by the scientific community.
The United States is the only major country not to have made the change.

15. Systems of Measurement Measurements
The metric system has advantages over the U.S. customary system and was the system chosen in 1960 by the General Conference on Weights and Measures. The official version is known as Le Système International d’Unités and is abbreviated SI.
Length
Defined in terms of a meter -- the distance traveled by light in a vacuum during a given time
Mass
Defined in terms of kilogram, based on a specific cylinder kept at the International Bureau of Standards
Time
Defined in terms of the oscillation of radiation from a cesium atom

16. A meter is about the same length as
a. a mile.
b. a yard
c. a foot.
d. an inch. B

17. Metric System
Length
6km
Mass
6kg
Time
6ks

18. A Metric Riddle Measurements
What are 10−12 boo, 10−3 pede, and 1012 dactyl?
Answer: A picoboo (peek-a-boo), a millipede, and a teradactyl (pterodactyl). ?

19. Systems of Measurement Measurements
Know:
1 Mm=106 meters
1 km = 103 meters
1 cm = 10-2 meter
1 mm =10-3 meter
1 mm = 10-6 meter
1 nm = 10-9 meter
1 pm=10-12 meter
1 hour= 3600 seconds
365 days = 1 year
Systems of Measurement Measurements
Fraction method…. Goal is to eliminate units
Great for multiple step conversions
(land speed record)

20. Which expression correctly converts 60 km/hour to meters per second?a. b. c. d. c

21. The Metric System Measurements
Multiply method works great within SI system
Know:
1 Mm=106 meters
1 km = 103 meters
1 cm = 10-2 meter
1 mm =10-3 meter
1 mm = 10-6 meter
1 nm = 10-9 meter
1 pm=10-12 meter
1 hour= 3600 seconds
365 days = 1 year
6 km = 6x103 m
6kg= 6x103 g
12ms=12x10-3 s

22. Trigonometry
Pythagorean Theorem
C2=a2+b2

23. Significant Figures A significant figure is one that is reliably known
In a measurement, the significant figures include the first estimated digit
Write 3 to 4 numbers for your answers

24. Successful Physics Learners:
Read your class notes each night
Read the story problem
Use Solid conceptual understanding: seeing a big picture
Draw a picture or diagram of the situation
Visualize what happens
Identify principle (heading)
list the givens

25. Successful Physics Learners
Apply physics concept to different situations
Choose equation (from assigned reading or summary at end of chapter)
Could be two equations two unknowns, don’t be afraid to list multiple equations and substitute givens
Use prior knowledge
Unit Conversions
365 days in a year
Basic trigonometry
Pythagorean theorem
Algebra

26. Successful Physics Learners
Use multiple approaches to attack problems
Use prior knowledge
Check to see if the answer is reasonable
are the units correct for the quantity being found?
check order of magnitude
are signs appropriate and meaningful?

27. Physics Learning
Use multiple resources: notes, book, homework, opening activities, etc…
Work in groups to clarify concepts and their relationships
Go beyond symbolic manipulation: plugging in #’s isn’t physics!
Do not memorize: learn when & why things work and when they don’t
Use tinyurl.com/marentette-wiki for student presentations
Actively participate!

28. Novice versus Expert Physics Learner
Novices see physics problems as object related
Experts see physics problems as concept based
