What every student should learn about Physical Sciences
• What is everything made of?(How do particles combine to form the variety of substances one
observes?)
• Why do things happen?– What force caused that action?
(How can one predict an object’s continued motion, changes in motion, or stability?)
• What is energy?(How is energy transferred between objects or systems?)

Is it Matter, Energy or a Force?
