Background For Teachers:
A physical change occurs when the appearance of a substance changes but its chemistry remains the same. No new substance is formed in a physical change; water moving between states of matter, a Popsicle melting, and a paper crumbled are examples of physical changes.
A chemical change occurs when bonds are broken between atoms and rearranged into new, entirely different substances such as burning a log and frying an egg.
Intended Learning Outcomes:
I. Using the balance - The students are going to find the mass of an object on the balance. They will physically change the form or shape of the object and see if the mass changes.
** Be careful to not lose any of the object along the way or else the two masses won’t be equal!!
II. Physical changes - Be sure and make predictions about the change in mass before each final mass reading is taken.
