Design and build a sleigh using a WeDo kit, K’nex or similar, that will pull a specific measured weight.
Students will use Lego WeDo kits or any other building kit such as k’nex, or geomags or craft materials to build the alligator or alligator mouth and then use a protractor to measure the angle of the mouth opening. Connecting math and the everyday world through the use of building an object to incorporate angle measurements. As an extension of learning students will then attempt to vary the measurement by adjusting the bands or speed of the motor if using wedo or programmable build kits or non-robotic version by adjusting the hinge of the mouth. Students should attempt to alter the build in efforts to change the angle.
