3. How this course works: There are 2 parts – a lab and a lecture. You should be enrolled in one lab section as part of this class. You will receive one grade combining your work in lab and lecture. Your lab grade depends on your participation and quality of work. Your lecture grade consists of: Class participation. Class participation. Quizzes. Quizzes. Exams. Exams.

4. The Keypads Keypads will provide instant feedback Keypads will provide instant feedback like “Who Wants to be a Millionaire” like “Who Wants to be a Millionaire” May sometimes use as quiz replacement May sometimes use as quiz replacement Unique keypad number for each person Unique keypad number for each person You can only use your own!!! You can only use your own!!!

5. I had chemistry as a… 1.Sophomore in H.S. 2.Junior in H.S. 3.Senior in H.S 4.in College… 5.I like ponies!

6. How do you feel about chemistry? 1.Easy 2.Some work but am confident… 3.A bit anxious 4.Terrified 5.Completely & utterly terrified…

7. How to succeed… Figure out what study strategies work best for you. Know your learning style… DO the work! Form study groups. Come see me! Ask questions!

13. Some Tools for Measurement: Have fun in lab Some Tools for Measurement: Have fun in lab

14. Units of Measurement: Metric System In the metric and SI systems, one unit is used for each type of measurement: MeasurementMetricSI Lengthmeter (m)meter (m) Volumeliter (L)cubic meter (m 3 ) Massgram (g)kilogram (kg) Timesecond (s)second (s) TemperatureCelsius (  C)Kelvin (K)

15. Metric and SI Prefixes

16. An equality states the same measurement in two different units. can be written using the relationships between two metric units. Example: 1 meter is the same as 100 cm and 1000 mm. 1 m= 100 cm 1 m= 100 cm 1 m= 1000 mm Metric Equalities

17. Know Scientific Notation Here are some numbers written in standard format and in scientific notation. and in scientific notation. Number in Number in Standard Format Scientific Notation Standard Format Scientific Notation Diameter of the Earth Diameter of the Earth 12 800 000 m 1.28 x 10 7 m Mass of a human Mass of a human 68 kg 6.8 x 10 1 kg Length of a pox virus Length of a pox virus 0.000 03 cm 3 x 10 -5 cm

18. . l 2.... l.... l 3.... l.... l 4.. cm The markings on the meter stick at the end of the orange line are read as The markings on the meter stick at the end of the orange line are read as the first digit 2 plus the second digit 2.7 The last digit is obtained by estimating. The last digit is obtained by estimating. The end of the line might be estimated between 2.7– 2.8 as half-way (0.5) or a little more (0.6), which gives a reported length of 2.75 cm or 2.76 cm. The end of the line might be estimated between 2.7– 2.8 as half-way (0.5) or a little more (0.6), which gives a reported length of 2.75 cm or 2.76 cm. Reading a Meter Stick

19. Known & Estimated Digits (Significant Figures) In the length reported as 2.76 cm, The digits 2 and 7 are certain (known). The digits 2 and 7 are certain (known). The final digit 6 was estimated (uncertain). The final digit 6 was estimated (uncertain). All three digits (2.76) are significant including the estimated digit. All three digits (2.76) are significant including the estimated digit.

20. . l 8.... l.... l 9.... l.... l 10.. cm What is the length of the orange line? 1) 9.0 cm 2) 9.03 cm 3) 9.04 cm Learning Check

21. Rounding Off Calculated Answers In calculations, answers must have the same number of significant figures as the measured numbers.answers must have the same number of significant figures as the measured numbers. often, a calculator answer must be rounded off.often, a calculator answer must be rounded off. rounding rules are used to obtain the correct number of significant figures.rounding rules are used to obtain the correct number of significant figures.
