Guided Notes:
Variables- an element, feature, or factor that is liable to vary or change.
Independent- a variable that will not change when something else does. Not depend on another.
Dependent- a variable that will change when something else does.
"If I change _____________ (IV), then _________________(DV) changes."

Exit Ticket:
Ernesto placed his spring launcher 3 notches back. Imani placed her spring launcher 2 notches back. Both exerted their spring launcher force on identical jar lids at the same time.
Question 15
