8TH GRADE SCIENCE Chapter 1 Lesson 1
ANYTHING THAT HAS MATTER AND OCCUPIES SPACE
MATTER
THE STUDY OF MATTER AND HOW IT CHANGES
CHEMISTRY
A SINGLE KIND OF MATTER THAT IS PURE
SUBSTANCE
A PROPERTY THAT IS MEASURABLE OR OBSERVABLE
PHYSICAL PROPERTY
THE BASIC COMPOSITION OF THE SUBSTANCE IS CHANGED
CHEMICAL PROPERTY
8TH GRADE SCIENCE Chapter 1 Lesson 2
A SUBSTANCE THAT CANNOT BE BROKEN DOWN INTO ANOTHER SUBSTANCE
ELEMENT
the smallest part of an element that has the same properties of that element Beryllium
Atoms are the smallest part of an element that has the same properties of that element Beryllium
ATOM
WHAT IS FORMED WHEN ATOMS COMBINE?
A CHEMICAL BOND
A GROUP OF TWO OR MORE ATOMS HELD TOGETHER BY CHEMICAL BONDS
MOLECULE
A SUBSTANCE MADE UP OF ELEMENTS BOUND IN A SET RATIO
COMPOUND
THE AMOUNT OF MATTER IN AN OBJECT
MASS
MEASUREMENT OF THE PROPERTIES OF MATTER USED BY SCIENTISTS
INTERNATIONAL SYSTEM OF UNITS (SI)
A GROUP OF 2 OR MORE ATOMS HELD TOGETHER BY A CHEMICAL BOND
Molecules Water
A SUBSTANCE MADE OF TWO OR MORE ELEMTNTS THAT ARE CHEMICALLY COMBINED IN A SET RATIO
COMPOUND
A COMPOUND SHOWING ELEMENTS OF THE COMPOUND AND THE RATIO OF ATOMS
CHEMICAL FORMULA
SUBSTANCES TOGETHER BUT ATOMS NOT CHEMICALLY BONDED
MIXTURE
8TH GRADE SCIENCE Chapter 1 Lesson 3
THE MEASURE OF THE FORCE OF GRAVITY ON YOU
WEIGHT
THE AMOUNT OF MATTER IN AN OBJECT
MASS
THE AMOUNT OF SPACE THAT A MATTER OCCUPIES
VOLUME
VOLUME OF IRREGUALR OBJECTS
THE MEASURE OF THE MASS OF A MATERIAL IN A GIVEN VOLUME
DENSITY
A SUBSTANCE THAT CANNOT CHANGE ONTO ANOTHER SUBSTANCE Physical and chemical reaction examples https://www.youtube.com/watch?v=yIJ2qnUOOwQ
PHYSICAL CHANGE
A SUBSTANCE THAT CHANGES INTO A DIFFERENT SUBSTANCE
CHEMICAL CHANGE
MATTER CANNOT BE CREATED OR DESTROYED
LAW OF CONSERVATION OF MASS
HOW HOT OR COLD A THING IS
TEMPERATURE
ENERGY THAT COMES FROM HEAT
