1September 17, 2009 Objectives: HP: SWBAT calculate density from experimental values.All: SWBAT calculate volume.All: SWBAT accurately and precisely measure mass, volume, an length.
2Thursday September 16, 2009 4-MINUTE Warm Up Convert the following:a) cm = ? mb) 12.0 cm = ? mmc) 1.0 g = ? kgCalculate the volume if the mass of water is 15.0g and the density is 1.00g/cc.(cc is short for centimeter cubed or cm^3)
3Metric Conversion Factors What you must know:1km = 1000m 1m = 100cm1kg = 1000g 1g = 100cg1kl = L 1L= 100cL1m = 1000mm 1cm = 10 mm1g = 1000mg 1cg = 10 mg1L = mL 1cL= 10 mL
4You Try In your classwork section: What conversion factor would you use to convert mm to meter?Convert 12.0mm to meters.Convert 1 km to cm. (A+)
5Lab Notebook Heading (top right corner of first page of EVERY lab) ex. Your Name: John DoeMr. NgDatePdTitle: (Every lab should have a title)
6Pre Lab (Due on day of lab) Pre-lab: Written before the lab. Includes a Title, Purpose, Hypothesis Procedure, Data Table and Observation Charts (shell), Analysis Questions*You write out these out. If there are no Data Tables, you must draw them.
7Lab Notebook Order Purpose/Hypothesis Materials Procedure Data & CalculationsAnalysisConclusion QuestionsSources of Error*the more specific and thorough you are for each, thebetter the grade.
8Procedures If not given to you: ex. Procedures: 1. Obtain two different pieces of tin foil labeled A and B.2. …* Be specific so that you may follow your procedures literally and specifically.
9Data TablesAlways label your data tables so that you may refer to them in your analysis or conclusion.Ex. In table 1.1, we see that the temperature increased from 11.2°C to 15.0°C.Make sure all units are labeled in ALL tables.
10Sample Data Table Sample A Sample B Density (g/cc) 2.7g/cc Mass (g) ….
11Finishing Up Calculation: Complete any calculations and show work with units.Conclusion:Was your hypothesis correct? Did you successfully complete your purpose? Why or why not (explain)Use numerical data to support your hypothesis.
12Homework Length Lab due in Folder HP: Density Lab due Tuesday (in Notebook)All: Chapter 2 Outline due MondayResponse due Sunday NightQuiz
