Step one of the Scientific Method
define the problem or ask a question
Step two of the Scientific Method
Research, what do we already know?
Step three of the Scientific Method
Form a hypothesis
What is a hypothesis?
A simple, testable, statement that’s easy to understand and that predicts the outcome
Step four of the Scientific Method
Test your hypothesis
Step five of the Scientific Method

What are cells made of?
Elements
What are elements made of?
Atoms
What are the three parts of an Atom?
Protons, Neutrons, and Electrons
When are Atoms most stable?
When their valence shell is filled (usually 8 electrons)
Ionic bond
The force connecting a positive atom with a negative atom
Covalent bond
The force between two or more atoms sharing electrons in their valence shells
Polar or non-polar bonding
The overall charge sometimes created by the pull on electrons by atoms
Chemical reaction
Atoms coming together or breaking apart
What is a theory?
After a lot of information has been gathered that supports a hypothesis it becomes a theory.
