What is Matter? Matter – 2 Properties – Has measurable volume – Has measurable mass *EVERYTHING IS MADE OF MATTER* 3 States of Matter – Solid – Liquid – Gas

Matter Has Volume ALL MATTER TAKES UP SPACE Amount of space taken up = objects volume Matter cannot share the same space at the same time

Measuring Volume Liquids – Graduated cylinder/beakers Meniscus – Units (metric) Liters (L) Milliliters (mL) Solids – Length X Height X Width – Expressed as cubic units (cm3, m3). *1mL = 1cm3 (cubic centimeters)*

Measuring Volume (cont.) Check yourself A book has a width 18cm, a height of 4 cm, and a length of 25cm. Calculate the volume: 18cm X 4cm X 25cm = 1800cm3 (cubic centimeters)

Measuring Volume (cont.) Gasses – Expands to fill it’s container – Volume of container = volume of gas in it.

Matter Has Mass Mass is a measurement of the amount of matter an object is made of Object’s mass can only change if amount of matter changes. – Breaking – Burning – Dissolving – Growing

Mass VS Weight Gravity – Force of attraction between objects due to mass – All matter has mass – all matter experiences gravity – Amount of attraction depends on 2 things Mass Distance

Check Yourself Imagine the following items resting side by side: an elephant, a tennis ball, a peanut, a bowling ball, and a house fly. In your journal list these objects in order of their attraction to earth due to gravity, from least to greatest amount of attraction. Explain why you arranged the items in the order you did. House Fly, Peanut, Tennis Ball, Bowling Ball, Elephant

Mass VS Weight Weight – A measure of the gravitational force exerted on an object – As distance between objects increases, the gravitational force decreases. – A brick floating weightless in space would weigh less than it does on Earth BUT it’s mass would remain the same. *An objects mass is constant – weight is not*

Mass VS Weight Standard unit of mass = kilogram (kg) grams (g) and milligram (mg) Standard unit of weight = newton (N) – 1N = 100g mass on earth

Inertia An object’s tendency to resist change in motion. Therefore: An object and rest will stay at rest unless acted on by an outside force. (Isaac Newton) And… An object in motion will remain in motion until acted on by an outside force (Isaac Newton)

Exit Slip 1.What are the two properties of matter? 2.How is volume measured? What units are used? 3.How is mass measured? What units are used? 4.Do objects with large masses always have large weights? Explain your reasoning.
