1. Matter has mass and volume.

2. Describe what matter is and demonstrate how to measure mass

3.  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

4.  Characteristics of a substance that can be observed without changing the identity of the substance o 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,

6. 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)

7. The moon has less gravity than Earth, so you weigh less but have the same mass.

8. Time to Self-Assess 5 – Mastered it! 4 – Own it! 3 – Getting there! 2 – Confused! 1 – No clue!

9. Describe what matter is and demonstrate how to use different methods to measure volume

10.  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 (cm 3 )

11.  Volume of a liquid – how much space it takes up in a container ◦ use graduated cylinder ◦ measure in milliliters (mL) ◦ 1 mL = 1 cm 3

12. 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 Irregularly shaped objects cannot use formula – use displacement

13. Time to Self-Assess 5 – Mastered it! 4 – Own it! 3 – Getting there! 2 – Confused! 1 – No clue!

14.  a measure of the amount of matter present in a given volume of a substance o unit – grams per cubic centimeter (g/cm 3 )  Density equals mass divided by volume (D = m/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 = ______ cm 3 D = ______ g/cm 3
