Entry task-September 26 Answer the following on the index card. I am taking roll using the index card so make sure that you turn one in: What measurement would a beaker of water in science class be measured in? grams, meters or milliliters What would a mass of a pencil be measured in? grams, pounds, meters or milliliters What would the length of a pencil be measured in in science class? grams, centimeters, feet or milliliters

Agenda 1. Entry task 2. Measurement in science notes 3. Review measurements in science and scientific notation 4. Metric conversions worksheet-turn in 5. Make sure you have turned in the daphnia lab and the heart rate lab and both conclusions. They are late but still worth points. If you have not turned these in you are not passing the course, please turn them in.

Measurement in Science The Metric System Please take notes on the following.

Metric system Decimal based Multiples of 10 Also known as International system of units

Length Based on the meter 1 centimeter=1/100 meter 1 Millimeter=1/1000 meter 1 kilometer=1000 meters

Mass The amount of matter in an object Weight is the measure of the pull of gravity on that mass Basic unit is grams 1 kilogram is 1000 grams 1 gram is 1000 milligrams

volume The amount of space an object occupies The basic unit is 1 liter 1000 milliters = 1 liter

Temperature Measured in degrees Celsius ( O C) 0 O C = freezing point of water 100 O C = boiling point of water Normal body temperature = 37 O C
