Properties of Matter By: Brianna Shields March 21, 2005
DO NOW • 1. What tool is used to measure temperature? • 2. What is one unit used to label temperature? • 3. What tool is used to view tiny organisms and objects that are too small for the naked eye to see?
GOAL • To be able to state the characteristics of matter • To use the proper equipment to measure various characteristics of matter
Length Definition: The distance between two points Tool: Ruler, Meterstick Unit: cm or mm or km Length
Mass Definition: The amount of matter in an object Tool: Triple Beam Balance Unit: grams Mass
Volume Definition: The amount of space an object takes up Tool: Graduated cylinder (liquids and irregular objects), or ruler (cubes) Formula for Cubes: V= lxwxh Units: ml or cm^3 Volume
Density Definition: The number of particles packed into a space Sinking or floating in water Need to measure mass and volume Formula: D = m/v Units: g/ml or g/cm^3 Density
Gravity Definition: Force of attraction between objects (amount of pull on Earth) Tool: Force Scale Unit: Newtons Gravity
Weight Definition: How much gravity pulls on an object Tool: Scale Unit: Newtons or pounds Depends on More mass = greater weight Closer to earth’s core = more gravity pull = more weight Weight
Inertia Definition: The resistance of an object to changes in its motion More mass = more inertia Inertia
Assessment • Decide which object has greater inertia. Explain
Assessment • Explain why this animation is an example of inertia
Assessment • Evaluate this statement: The people in the diagram have the same mass, but different weights. How is this possible?
Assessment • A cube has a length of 2cm, a width of 3 cm and a height of 4 cm. It also has a mass of 48 g. What is it’s density? Will it sink or float when placed in water?
Assessment • A liquid has a mass of 12 g and a volume of 36ml. What is it’s density? What will happen if it’s poured into a cup of water?
Assessment • Which of the two cubes has a greater density? Explain
Assessment • What is the volume of liquid in each graduated cylinder?
Assessment • What is the volume of this cube? 1 cm 7 cm 3 cm
Assessment • What is the mass of this object?
Assessment • What is the mass of this object?
Assessment • What is the mass of this object?
Assessment • Work with your partner on the “Measurement Practice” sheet • You will be performing a variety of measurements on several objects • We will go over the answers when you have completed it
