  1. Syllabus for INSC310 • In-class participation(30%) – need clickers by Thursday (9/1) • Journal (10%) – due every Monday by 8 am in LON-CAPA (LC) • Homework (30%) – due every Monday by 8 am in LC • Quizzes (20%) – due bi-weekly on Monday by 8 am in LC • Final Exam (10%) – online from Friday, Dec 9 to Friday, Dec 16

  2. INSC310 Syllabus Questions 1. A clicker is used for your lecture participation grade. If your clicker is broken or has dead batteries, can you still get credit that day? (a) yes (b) no 2. How many participation grades can you drop? 3. This course uses an online homework system called LON-CAPA (30%). Have you used LON-CAPA before? (a) yes (b) no 4. How many LON-CAPA homework scores can you drop?

  3. INSC310 Syllabus Questions 5. LON-CAPA quizzes are "open" from Thursday at 9am to Sunday at 11pm and have a time limit of how many minutes? 6. If you use two "tries" to get the correct answer on a quiz problem, what percentage of the points do you earn? 7. How many LON-CAPA quizzes can you drop? 8. Can you under special circumstances make-up a journal, homework, or quiz? (a) yes (b) no ANY QUESTIONS?

  4. Activity Containers • In your container are some items that you will use frequently throughout the semester. • It is your responsibility to maintain them. • Please clean and dry all items before putting them back. • If you are missing an item you should make sure that you notify me, or replace it yourself. • Please write this list on construction paper (leave room in case we add things), along with your table #. Items list: 1 timer 2 rulers 2 thermometers 3-4 plastic cups 1 container of salt 1 container of baking soda 1 set of measuring cups 1 small graduated cylinder 1 funnel

  5.  Concept Recap 1a • Activity Containers: • Materials • Responsibilities

  6.  Concept Recap 1b How will you be graded?

  7. Basics: Size & Mass • Metric Length (mm, cm, m, km)Activity = ruler + meter stick • Metric Mass (g, kg) and Volume (L, mL, cm3, cc)Activity = wood blocks

  8. Metric Systemor (SI = Système International d'Unités) Jean Baptiste JosephDelambre Pierre François AndréMéchain • Originated after French Revolution = “new measurement system in a new world.” • Meter = one ten-millionth of distance from north pole to equator. (10,000,000 m = 1/4 distance around world) • Two French astronomers led expeditions from Paris (1792-1799) to measure the meridian arc from Dunkerque to Barcelona. • What three countries do NOT use the metric system? • What is 10,000,000 meters in kilometers?(a) 10 (b) 1,000 (c) 10,000 (d) 100,000

  9. Who uses the Metric System? • What countries do not use SI units? (answer in numeric order)(a) US (b) India (c) Myanmar (d) Egypt (e) Australia

  10. Basics: Metric (or SI) System • Metric system is a “foreign” language for many of us, but we use “SI” in science! • If you don’t “think” in metric, then you must PRACTICE converting from metric to “common” units EVERY time you see it! 1 meter= 39.4 inches (~3.3 ft) or 1 inch = 2.54 cm • How many inches are in 10 feet? • How many feet are in 10 inches?

  11. ACTIVITY with Metric Measurement • Use ruler or meter stick to measure common items and start “thinking metric!” • How can you “remember” the size of a meter, cm, or mm?

  12. ACTIVITY with Metric Measurement (wrap-up) Give your groups interpretation, then engage class for additional comments • What was the point of this activity? • Explain how you would introduce this to your class. • Where do you see a student having difficulty with this? • What changes or extensions could you do to this activity?

  13. Questions: LengthConversions If a wire is 0.01 m thick, how many millimeters is that?(click in numeric answer to nearest integer!) A typical door is 2 m tall. That would be 6 feet and how many inches? How many meters in a mile?

  14. Distance: Kilometers (km) 1,000 m = 1 km = 0.62 mi OR1.6 km = 1 mile km/h 100 km/h=62 mph

  15. Questions: DistanceConversions A BMW is driving 140 km/hr on the German autobahn, how fast is that in mph? (to nearest integer) What is the circumference of the earth in kilometers? Hint: Look back at the slide about the definition of the meter!

  16. ACTIVITY with Solid/Liquid Volume Demonstration 1 Liter of Blocks Equal Volume Shapes • Each block has dimensions 2 cm × 2 cm × 2 cm ( = 8 cm3 or cc or ml). • How many blocks does it take to make 1000 cm3 or 1 liter? Equal Volume Containers

  17. ACTIVITY with Solid/Liquid Volume (wrap-up) • Give your groups interpretation, then engage class for additional comments • What was the point of this activity? • Explain how you would introduce this to your class. • Where do you see a student having difficulty with this? • What changes or extensions could you do to this activity?

  18. Mass: Kilogram 1 kg= 2.2 pounds • The official kilogram is a cylinder composed of 90% platinum and 10% iridium located in Paris. • How can you quickly calculate this conversion in your head? • NOTE: Actually, kilograms are a measure of “mass” and pounds are a measure of weight (or gravitational force). The conversion above is only true on the Earth!

  19. Questions: MassConversions An elephant has a mass of 5,000 kg. How many pounds does it weigh? John Skrobiszewski weighs about 176 lbs. How many kilograms is that?

  20. Water Mass and Volume: Liter (L) Bottle 1 kg 1 L =1.1 quarts 1 gallon = 3.8 liters 1 L H20  1 kg 1 L H20

  21. Questions: Mass of Water What is the mass in kg of a bucket of water with a volume of 10 L? What is the mass in grams of 1 mL (or 1 cm3) of water? [1 L = 1000 mL] What is the mass in grams of the soda (~350 mL) in a Diet Pepsi can?

  22. Concept Recap 2a Explain this picture. Create a problem where you have to convert from cm to km and explain how to do it.

  23. Concept Recap 2b Explain this picture. Explain how you would determine the mass of water given the volume and do a conversion for the class.

  24. Appendix: Factors of 1000

  25. Appendix: DistanceValues Speed of Light = 3×108 m/s or 300,000 km/s Light year = 300,000 km/s × (3.15 ×107 s/yr) = 9.5 trillion km
