Inquirers Knowledgeable Thinkers Principled Communicators Open-Minded Caring Risk takers Balanced Reflective According to a CIA 2007 report Mission Statement: Renton High School aims to provide effective instruction and support services to enable students to acquire 21st century skills, develop international mindset, enhance knowledge, and nurture the ability to make thoughtful decisions. Our students will graduate: -on-time, -empowered to be successful in a college, technical or professional program, -prepared to compete in the global workforce, and -ready to serve our pluralistic community. Length/Distance: mm, cm, m, km Volume: mL, L, cm 3 Mass: mg, g, kg Temperature: C All units are base 10! 1000 milligrams = 1 gram 100 centimeters = 1 meter 1000 g = 1 kilogram 1000 m = 1 kilometer This means when you do conversions you only have to know how to move decimals! Significant figures (sig figs)- digits that we know for sure plus one estimated digit. Read the # right of screen Shows a Mass of g. The this has 4 sig figs. If the mass read 3.24 g than it would be 3 s.f. You must estimate one extra digit than you know for sure. Top ruler shows 1 decimal so you estimate a 2 nd. (3 sig figs here) Bottom Ruler shows none so you estimate 1. (2 sig figs here) Graduated cylinder Marking every mL. Record volumes with 1 decimal place. Ex: What is this volume? No decimal: Everything EXCEPT 0s at the end (4100 2 sig. fig.s) Decimal: Everything EXCEPT 0s at the beginning ( 2 sig. fig.s) (1000. 4 sig. fig.s) ( 5 sig. fig.s) If the number is in Scientific notation: Everything before the x 10 something (1.540 x 4 sig. fig.s) (1.2 x 2 sig. fig.s) Count the sig. fig.s: x Split up and go into the lab and make the required measurements. Use the correct # of sig figs. Dont put anything heavier than a beaker on the small scale. Check your results with me. Share your results with your group. Now that you have made measurements use those to make predictions about: a. temperature outside in December. b. Temperature of boiling water. c. Length of the room. d. Mass of a full can of soda. e. Volume of a full can of soda f. Distance from here to Coulon beach. Write a full prediction: Ex: I think my wingspan is about 1.5 meters because I measured the width of the lab bench to be almost 1.4 meters and my wingspan is a little longer than that. 1. Which metric unit would be most appropriate for measuring the following? a. Mass of a couch (sofa): b. Length of a outdoor play field: c. Temperature of the ocean: 2. How many significant figures do the following numbers have? a b c d
