Explore possible sources of error in a volume lab experiment where water samples of 100.0 mL were measured by students using graduated cylinders. Learn about measurements, SI units, scientific notation, and more. Pass your graphing packets forward and start with sections A & D to manage time effectively.
E N D
ICP 8/22/12 Volume Lab
Warmup • A scientist carefully measured a sample of water to be exactly 100.0 mL in volume. Groups of students measured the water using a graduated cylinder. These are the measurements that each of the groups got: 102 mL, 100 mL, 101 mL, 99 mL, 97 mL, and 97 mL. Give a detailed explanation of some possible sources of the error.
Quiz Thursday • SI Units and converting between units • Scientific Notation • Making Measurements (Triple Beam Balance, Graduated Cylinder) • Observation vs. Inference • Graphing • Types of Graphs
Agenda • Pass your graphing packets forward. • Volume Lab • Start with sections A & D. (I don’t want to run out of time for section D.) • Get to sections B & C last.
