Chemistry- 8.P.1- Understanding the properties of matter and changes that occur when matter interacts in an open and closed container
--A characteristic that you can observe without changing it. (Using your sense)
Ex. Color, Shape, Texture, Smell, Size, State of matter
-- A characteristic that you can only observe by changing the substance. (How it reacts)
Ex. Flammability, Reactivity, Oxidation, Toxicity
-- Doesn't form a new substance.
Ex. Chopping Something Up, Melted Ice Cream, Jelly On Toast
--Substances changed into new and different ones.
Ex. New Color, Heat, Light, Sound, Gas Bubbles, Change In State Of Matter,Unreversable
-- Made of one type of atom.
Ex. Periodic Table
-- Made of 2 or more different atoms that are put together.
-- Made of 2 or more pure substances
Ex. Heterogeneous, Homogeneous
--A table that contains all the Elements found
**Groups and Periods
**Metals, Non-Metals, and Metalloids
**Atomic Number, Atomic Mass, Protons, Neutrons, Electrons
*The Law Of Conservation Of Mass
-- Matter can be neither create nor destroyed.
Ex. Wood > Fire > Ash
-- Compound, Mixture, Element, Solution, Atom, Matter
--Atomic Number, Atomic Mass, Periods, Groups, Physical and Chemical Properties
-- The youngest layer at the top and oldest at the bottom.
Ex. No example
-- A fossil of a living organism that lived during a short period.
-- A piece of ice that shows the temperature of past years.
Ex. No example
*Geologic Time Scale
-- Eras and epochs/ Earth history time line
Ex. Precambrian Era
-- The specific age using a rock to determine it.
Ex. No example
--The specific age of a fossil
Ex. Radioactive dating
--Time it takes for 1/2 of the isotope to decay.
-- Geology, Law of superposition, Ice cores, Relative dating, Absolute dating, Index fossil,
-- A tiny organism that causes disease.
Ex. Bacteria, Virus, Fungi, Parasite
-- A living organism that causes and spreads disease.
-- A non-living organism that infects living things.
-- A type of algae
-- A type of microscopic, unicellular, living organism.
-- An outbreak in a small area or city.
Ex. Small pox
-- An outbreak that spreads all over from one country to the next.
-- take care of it before you get sick.
Ex. washing your hands, not wearing someone else shoes, Take off sweaty socks,
taking a vaccination
-- A helper when your sick.
Ex. Antibiotics, keeping yourself clean
-- The use of living cells to make useful products.
Ex. Vaccination for animals
-- A job
Ex. Validation specialist, medicine specialist, biotech engineer
-- Agriculture is affected by biotech because It helps out a lot when our population is growing. Medicine is affected by biotech because we can make better medicines to cure many unreachable diseases. Economy is affected by biotech because we all need something better and we are able to sell many other things to many other states so we could make more money.
