Chemistry-8.P.1 Understand the properties of matter and changes that occur when matter interacts in an open and closed container.

-Physical And Chemical Properties

Physical Change-Does Not Form A New Substance

Characteristic that you Can Observe Without Changing the composition of the substance

Chemical Change- One Or More Substances Are Changed Into New Substances That Have New And Different Properties.

Physical Properties-Can Be Observed Or Measured without changing It.

Chemical Properties-Flammability,Reactivity,oxidation,toxicity

Compound Mixture Element

Element-Building Blocks Of Matter Made Of Atom

Compound-Substance formed when two or more elements chemically combined

Mixture- Combination of two or more different substance that in mixed but not combined.

Periodic Table

A Table Of The Chemical Element Arranged In Order Of Atomic Number.

Groups, Periods

Groups- They Go Vertical Up And Down

Periods- They Go Horizontal From Left To Right

Metals In Periodic Table:

The metals have a moderate range of relativity and a wide range of properties . In general they are shiny and good heat and electricity

Non Metals:

Are not able to conduct electricity and heat very well as non-metals. They are very brill

and can not be made into wires or pounded into sheets

Metalloid- are the elements found along the stair-step line that distinguishes metals from non-metals

Atomic Number-Number Of protons and electrons in a atom of 1 element .

Atomic Mass- The Sum of protons and neutrons in the nucleus of an atom

Protons and Electrons Are The Same Number

Protons And Neutrons Are Both Nucleus

Law Of Conservation- It Cant Be Destroyed Or It Cant Be Created


Earth History

Law Of Superposition- Younger rocks lie above older rocks if the layers have not been disturbed.

Index fossils- A Fossil that is found in the rock layer of only on geologic age and is used to establish age of the rock layer around the world.

Ice core- A Sample of Ice From A Layer To Look At Earths Climate From Many Years Go.

Geologic Time Scale- Scientist Use to know about the old ages of the Earth Different Times In The Past.

Relative Age- of rock giver as the year since the rock formed

Half life- Is The Time Required for Exactly half of the entities to decay

Radioactive decay-process by which a nucleus of an unstable atom loses energy


Infectious Diseases

Microorganism (Virus,Bacteria, Fungi, Parasites)

Virus- small infection that reproduce only inside of living cell and then spreads and can cause disease

Bacteria- Microorganism made up of a single cell that has no distinct nucleus

Fungi- A fungus is any member of a large group of Eukaryota organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.

Parasites- an organism that lives on or in an organism of another species, known as the host, from the body of which it obtains nutriment.

Epidemic vs. Pandemic:

Epidemic is a widespread out break of an infectious disease within a small population or community.

Pandemic- is an out break of an infectious disease that affects large populations.

Prevention AndTreatment:

Prevention can be raising awareness, Education on the disease, Good Hygiene, Vaccines/Antibiotics

Treatment can be seen as treating a diseases but different diseases require different treatment

Biotechnology is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use
