How can you make a sculpture that looks like it is moving? Sculptors use curves, lines, and texture to create the
feeling of movement. Some sculptures actually move. Delicately balanced sculptures that move in the wind are
called MOBILES.
PROJECT GOAL: Create a mobile that illustrates many of the properties of triangles, parallel lines, and symmetry.
DESIGN A MOBILE
Work with a partner to design a mobile. Decide how to meet each requirement below. Make a sketch of what
you would like your mobile to look like.
STEP 1: Construct &amp; cut-out at least 1 isosceles, 1 scalene, &amp; 1 equilateral triangle
using construction paper, cardstock, or cardboard.
STEP 2: Construct &amp; cut-out a fourth triangle that is congruent to one of the other
3 triangles.
STEP 3: Draw one angle bisector, altitude, median, and perpendicular bisector on
any or all of the triangles.
STEP 4: Balance at least one triangle at its &quot;centroid&quot; (intersection of medians).
STEP 5: Illustrate at least one of the properties or theorems we have covered. (e.g.: SAS, SSS, etc)
BUILD IT
Materials you may use include cardboard, string, tape, staples, straws, wire, or sticks.
Balance your mobile so it moves in a gentle breeze or when you touch it. It will take some patience to balance the mobile. Don't
give up! If your mobile has more than one level, balance it from the bottom up.
PRESENTATION
On your diagram write a brief description of your mobile. Include an explanation
of how your mobile meets each of the requirements above.
Compare your finished mobile to your diagram. If you were to build another
mobile what would you do differently? What tips would you give another
