Thursday September 26 List 3 physical properties.
Reading Guide • What are observations? • (your answer)
What are some things that you have observed today? • People walking • Clothes • Sounds
Name some physical properties • Color • Shape
What senses do you use to observe? Give 1 example of each. • Eyes—seeing • Ears—listening • Tongue-tasting • Nose—smelling • Fingers-touch
Name some things that are matter and some things that are not matter. • Color • Shape
Why are color and shape physical properties? • Because they describe
What are some examples of physical change? • Detergent bottles • Cutting paper • Tearing paper • Anything that changes without changing • Hair color • Hair cuts • Name some more
How are physical changes and properties different? • Physical property: identifies the material • Physical changes: the physical property is changed but the identity does not change.
What objects could you use length to organize? • A book shelf • A classroom • An aisle at the grocery store

What is volume? • Is the amount of space an object takes up
What is density? • The amount of mass a material has in a given volume.
How are mass, volume and density different? • Mass is the amount of matter in an object. • Volume is the space the object takes up. • Density is the amount of mass in a given volume.
How is volume different than area? Volume is the space the object takes up. The area is the inside shape or space measured in square units.
Give examples of density. IS THE AMOUNT OF MASS A MATERISAL HJAS IN A GIVEN VOLUME. • FLOAT • DON’T FLOAT • ICEBERGS FLOAT BECAUSE SOLID ICE HIS LESS DENSE THAN LIQUID WATER • HYDROGEN IS USED TO INFLATE WEATHER BALLOONS BECAUSE IT IS MUCH LESS DENSE THAN AIR. • DENSITY OF WATER: 1 GRAM/CUBIC CENTIMENTER
