International System Of Units (Metric System). Types of Measurements. 1- QUALITATIVE MEASUREMENTS: observations of reactions — changes in color and physical state. 2- QUANTITATIVE MEASUREMENTS : which involve numbers . Use SI units — based on the metric system.

Chapter 3 Review “Scientific Measurement”. Pre-AP Chemistry Charles Page High School Stephen L. Cotton. Chapter 3 Review. A cubic meter is about the same as the volume occupied by a: a) basketball arena, or b) washing machine?

CH. 2 - MEASUREMENT. I. Using Measurements (p. 44 - 57). A. Accuracy vs. Precision. Accuracy - how close a measurement is to the accepted value Precision - how close a series of measurements are to each other. ACCURATE = CORRECT PRECISE = CONSISTENT. your value. accepted value.

Significant Figures & Scientific Notation. Physics. Significant Figures. Indicate accuracy of measurements Several rules for # of significant figures.. Non-zero digits are always significant. Any zeros between two significant digits are significant.

Significant Digits. Non-zero digits are always significant 291 has three significant digits 29.18 has four significant digits Zeroes placed before other digits are not significant 0.095 has two significant digits Zeroes placed between other digits are always significant

Methods of Counting Bacteria. Direct microscopic Most probable number Standard plate count Coulter counter Turbidity (optical density) – this is an indirect method. Standard Plate Count.

The Nature of Science. Chapter 1 introduction to science. Objective. COS 12.0 Identify the metric units used for mass, temperature, time and length (distance). What is science?.

Multiplying and Dividing. By: Jenny Erickson. Multiplying in Scientific Notation. Multiplying…. The general format for multiplying is as follows… (N x 10 x )(M x 10 y ) = (N)(M) x 10 x+y First multiply the N and M numbers together and express an answer.

Chemistry 1 – McGill Chapter 3 Scientific Measurement. WARNING: Learn it now...it will be used all year in Chemistry!!!. 3.1 Qualitative measurements measurements that give results in a descriptive, non-numerical form. Examples:. He is tall. Electrons are tiny. Quantitative measurements
