Do Now Skim through lesson 1.1 and write down 2 new facts that you want to learn more about.

Matter has mass and volume. Matter & Energy 1.1 Matter has mass and volume.

Describe what matter is and demonstrate how to measure mass Learning Goal: Describe what matter is and demonstrate how to measure mass

I. All objects are made of matter. Anything that has mass and takes up space solid, liquid, and gas Made of atoms (too small to see) Light & sound are not matter – does not have mass or take up space

Physical properties describe a matter. Characteristics of a substance that can be observed without changing the identity of the substance Use all 5 senses Qualitative (Quality) Deals with descriptions. Observed but not measured. Colors, textures, smells, tastes, appearance, beauty, etc. Quantitative (Quantity) Deals with numbers. Data which can be measured. Length, height, volume, mass, speed, time, temperature,

Qualitative vs. Quantitative

II. Mass is a measure of the amount of matter Measuring mass compares the mass of the object to a standard unit Weight – the downward pull on an object due to gravity standard unit is kilogram (kg) base unit is gram (g) Use a (triple) beam balance to measure mass Gravity – force that pulls objects together measured by using a scale (spring scale) standard scientific unit – newton (N) common unit – pound (lb)

Mass & weight are related but not the same The moon has less gravity than Earth, so you weigh less but have the same mass.

Learning Goal: Describe what matter is and demonstrate how to measure mass Time to Self-Assess 5 – Mastered it! 4 – Own it! 3 – Getting there! 2 – Confused! 1 – No clue!

Learning Goal: Describe what matter is and demonstrate how to use different methods to measure volume

III. Volume is a measure of the space matter occupies All matter takes up space air takes up the space inside a basketball Volume of regularly shaped objects can be calculated using a formula Volume = length x width x height (V = lwh) Units of volume – centimeters cubed (cm3)

Volume of a liquid – how much space it takes up in a container use graduated cylinder measure in milliliters (mL) 1 mL = 1 cm3

Irregularly shaped objects cannot use formula – use displacement 1. Use a graduated cylinder to measure a volume of water 2. Place object in water, note the new volume of the water 3. Subtract the original volume from the second volume, the difference is the volume of the object

Learning Goal: Describe what matter is and demonstrate how to use different methods to measure volume Time to Self-Assess 5 – Mastered it! 4 – Own it! 3 – Getting there! 2 – Confused! 1 – No clue!

Density a measure of the amount of matter present in a given volume of a substance unit – grams per cubic centimeter (g/cm3) Density equals mass divided by volume (D = m/v) M D V A block of metal has a mass of 12 grams and a volume of 8 cubic centimeters. What is the density of the block? M = ______g ____ / ____ = ____ V = ______ cm3 D = ______ g/cm3
