PHYSICAL SCIENCE

At the conclusion of this unit you will understand that…

• Matter is defined by its physical and chemical properties.
• All matter is made up of atoms.

Inquiring scientific minds will be able to answer these essential questions…

• What is matter?

• What are the basic units of scientific measurement?
• How do we measure length, mass, volume, and density?

• What is the difference between physical/chemical properties and changes?
• How are chemical and physical properties used to identify matter?
• How is matter constantly changing?
• What are the three states of matter?
• How does energy cause matter to change state?
• What is the structure of an atom?
• How is the periodic table arranged?
• What is the difference between an element and a compound?
• What is the difference between renewable and non-renewable resources?
• What is the relationship between matter and energy?
