This is made up of two or more substances -- elements, compounds, or both -- that are together in the same place but are not chemically combined.
What is a mixture?
100
The study of the properties of matter and how matter changes.
What is chemistry?
100
The measure of the force of gravity on you and every object on Earth.
What is weight?
100
Any change that alters the form or appearance of matter but does not make any substance in the matter into a different substance.
What is a physical change?
100
The total energy of all of the particles in an object.
What is thermal energy?
200
In this type of mixture you can see the different parts.
What is heterogeneous?
200
The two types of properties that every form of matter has.
What are physical and chemical properties?
200
The measurement of the amount of matter in an object.
What is mass?
200
Changes of state, shape, or form are all this type of change.
What is a physical change?
200
This type of change occurs when energy is taken in or absorbed.
What is endothermic change?
300
The substances in this type of mixture are so evenly mixed that you can't see the different parts.
What is a homogeneous mixture?
300
The basic particle from which all elements are made.
What is an atom?
300
The equation for density.
What is mass over volume?
300
This type of change produces a new substance with properties different from those of the original substances.
What is a chemical change?
300
This type of change occurs when energy is released.
What is an exothermic change?
400

400
The simplest substances found on Earth.
What are elements?
400
The amount of space that matter occupies.
What is volume?
400
Matter can be neither created or destroyed, only rearranged.
What is the Law of Conservation of Mass/Matter?
400

500
Trace the transfer of energy from the sun to your ability to walk.
What is electromagnetic energy from the sun -> chemical energy in plants ->when eaten by you the chemical energy is converted to kinetic energy which allows you to move?
