Activity
1: Cubic Volume Models
|
Activity
2: Physical Manipulation of Rational Equations
|
|
Students
make paper models of a cubic centimeter and cubic decimeter.
|
Students
learn the rules for moving variables in rational equations
by moving physical variables on a template.
|
|
Activity
10: Hands-On Salt Formulas
|
Activity
11: Physical Unit Conversion Method
|
Students
color, cut out and organize paper ions into their positions
on the periodic table. They then use the "ions"
to help them balance charges in ion combinations and write
correct salt formulas.
|
Students
use beans, buttons, and other small objects to study the
downstroke upstroke and dual conversion cancellation patterns
used in unit conversion problems.
|
|
Activity
12: Balancing Chemical Equations
|
|
Students
use colored beans (or M&M's or Skittles) to study the
meanings of subscript and coefficients in chemical equations.
They learn the rules for balancing equations and are able
to transfer their knowledge to more sophisticated problems.
