All changes in matter involve:
energy
Moving objects have:
chemical energy
potential energy
electrical energy
kinetic energy
The energy an object has due to its position in relation to a force.
chemical energy
potential energy
kinetic energy
electrical energy
This energy is stored in different substances that during chemical reactions is converted into other forms.
kinetic energy
chemical energy
potential energy
electrical energy
We can see this type of energy in some natural phenomena such as lightning.
electrical energy
potential energy
chemical energy
kinetic energy
This is the energy that travels with light. Plants use this energy for photosynthesis.

Matter exists in many different forms. We call these forms:
animals
substances
minerals
vegetables
Wood, plastic, air, carbon, and diamond are examples of:
animals
minerals
substances
vegetables
There are two types of matter:
pure substances & mixtures
renewable & non-renewable
heterogeneous & homogeneous mixtures
animals & vegetables
They contain only one type of material
renewable materials
animals
heterogeneous mixtures
pure substances
Oxygen, gold, salt, sugar, and other minerals are:
renewable materials
pure substances
animals
heterogeneous mixtures
They contain two or more pure substances:
heterogeneous mixtures
animals
renewable materials
mixtures
Chocolate milk is an example of a:
animals
renewable materials
mixture
heterogeneous mixtures
In these mixtures, the different substances that form the mixture can be distinguished
renewable materials
alloys
heterogeneous mixtures
homogeneous mixtures
