Let's Tie This All Together
Physical Science is any of the natural sciences dealing with inanimate matter or with energy, as physics, chemistry, and astronomy. This branch of science is primarily concerned with the nature and properties of matter and energy and include topics such as mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms. It also includes chemistry which is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Study of natural nonliving matter & energy Chemistry Physics Astronomy Energy In Physical Science Brook’ s experiment showed how chemicals could be used to create light.

What are the properties of this item?
Even though these are both paper clips, they have different properties because they are made of different materials.
Physical Properties: characteristics that can be observed and measured without changing the chemical makeup of the substance
What properties could you use to describe a material? ** Several items are in your group’s envelope ** Make a table and list the properties of each item Item Paper clip Toothpick Properties
List one or more properties that could be used to distinguish each material from all of the others. Item Paper clip Toothpick Properties Unique
Why isn’t each batch of salsa equally hot (spicy)? Which is better to stir boiling candy, a wooden spoon, a plastic spoon, or a metal spoon? Why?
Malleability: able to be hammered and molded without shattering Is graphite malleable? What about a marble?
Ductility: Ability to be stretched Is wood ductile?
Ability to go back to original shape after being stretched
Viscosity: Tendency of a fluid to keep flowing; Greater viscosity = flows slower How does temperature affect viscosity?
Hardness: can scratch another Or how easily it can be scratched
Density: Ratio of the substance’s mass compared to the volume
