1. HW Due YouTube Video Tonight’s HW Metric HW handout #1 (will receive at end of class) and watch a Dimensional Analysis Video of your choice. Finish today’s Dim. Analysis problems #1-10 if necessary Do Now September 17 & 18

2. On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with #1 1.No clue what’s going on 2.Kinda got it, but then you lost me 3.Ehh…I’m ok 4.I think I got it, but I’d like more practice 5.So confident I could teach it to someone right now

3. On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with #2 1.No clue what’s going on 2.Kinda got it, but then you lost me 3.Ehh…I’m ok 4.I think I got it, but I’d like more practice 5.So confident I could teach it to someone right now

4. In which problem was the math easier? 1.#1 2.#2 3.Equal! Both 1 & 2 4.I really had NO IDEA what was going on at all in

5. Bill Nye What did you learn? Anything interesting? Did you find the error? Anything confusing? Any comments?

6. Metric Patrol NO ALCOHOL OR PRESCRIPTION MEDICATIONS (Tylenol, Advil, etc is ok)

9. Do Not lose this paper! You will need to reference it all year!

10. Lesson 1: Length T. Trimpe 2008 http://sciencespot.net/

11. English vs. Metric Units Left Image: http://webapps.lsa.umich.edu/physics/demolab/controls/imagedemosm.aspx?picid=1167 Right Image: http://share.lancealan.com/N800%20ruler.jpg Which is longer? A. 1 mile or 1 kilometer B. 1 yard or 1 meter C. 1 inch or 1 centimeter 1.6 kilometers 1 mile 1 yard = 0.9144 meters 1 inch = 2.54 centimeters

12. Metric Units The basic unit of length in the metric system is the meter and is represented by a lowercase m. Standard: The distance traveled by light in absolute vacuum in 1⁄299,792,458 of a second. Complete each statement with Metric Units 1 Kilometer (km) = 1000 meters (m) 1 Meter = 100 Centimeters (cm) 1 Meter = 1000 Millimeters (mm) Which is larger? A. 1 meter or 105 centimeters B. 4 kilometers or 4400 meters C. 12 centimeters or 102 millimeters D. 1200 millimeters or 1 meter

13. Measuring Length

15. Dimensional Analysis 1030 cm = ______ m? 1030 cm. __1_m 1 100 cm 1030 m 100 10.30 m OR 10.3 m

16. Use Metric Magic and Dimensional Analysis to complete the following problems. Need help? Ask a friend or ask a teacher. SHOW ALL WORK, round to at least 2 decimal places! 10. CHALLENGE! _____________________________mm = 1 mile

17. Do you prefer… 1.Dimensional Analysis (I’m a numbers person! 2.Ladder Method (way easier) 3.Either – I can see the benefits of both methods

18. On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with the LADDER METHOD 1.No clue what’s going on 2.Kinda got it, but then you lost me 3.Ehh…I’m ok 4.I think I got it, but I’d like more practice 5.So confident I could teach it to someone right now

19. On a scale of 1-5 (1 being the least, 5 being the most) how CONFIDENT are you with DIMENSIONAL ANALYSIS 1.No clue what’s going on 2.Kinda got it, but then you lost me 3.Ehh…I’m ok 4.I think I got it, but I’d like more practice 5.So confident I could teach it to someone right now
