Mid- Year Review

Chemistry, Earth History, Infectious Diseases

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

*Changes they undergo

-Physical and Chemical Change

* any change that does not involve a change in the substance's chemical identity

-Elements, Compounds, and Mixtures

* Elements are made of one type of atom while compounds are made of 2 or more atoms while mixture is a combination of 2 or more pure substances.

-Periodic Table

* Table of metals, metalloids, and non-metals

-Groups and Periods

* Horizontal rows are called periods and the vertical rows are called groups.

-Metals, Non-Metals, Metalloids

* They are all parts of the periodic table going from right to left are the metals, then the metalloid, and last non-metals.

-Atomic Number, Atomic Mass, Protons, Neutrons, and Electrons

*The atomic number for an atom is the equal number of protons in the nucleas, the atomic mass is the number of protons and neutrons in an atom

-Law of Conservation of Mass

*i don't know








Earth History

-Law of Superposition

each layer of rock that is on the bottom of one is older and the one on top is younger

-Index Fossils

fossils are widely distributed organisms that lived during only one short period.

-Ice Cores

a peace of ice that sis used to see what the carbon dioxide levels were long ago

-Geologic Time Scale

the timescale of rock layers and the fossils in them.

-Relative and Absolute Dating

Relative- Close to the actual date/ Absolute- The exact date and time

-Half-Life/Radioactive Decay


Relative and absolute dating

Infectious Disease


*small living organism

-Virus, Bacteria, Fungi, Parasite

*Virus- small non living organism bacteria- small living organism that infects people/ fungi- small living organism that can give you ring worm/ Parasite- small living organism that moves from host to host

-Epidemic vs. Pandemic

*epidemic- small virus in a community/ Pandemic- Virus across a continent or world wide


*Prevention- keep it from happening/ Treatment- treat it and get it out of your system and taken care of


*The study of life science


* Agricultural science

-Agriculture, Medicine, Economy

* Farmers get more money if they grow their crops with enhanced chemicals to make them bigger than usual. Biotechnologist make medicines more enhanced for better treatment.


* Parasite



* Fungi

* infectious Disease

* Microorganism

* Pandemic

* Epidemic
