The Gravity Games An Integrated 9 th Grade

The Gravity Games An Integrated 9 th Grade Math, Science and Engineering Curriculum Resource Robo Educator Authors Terri Varnado Dan Ward Marie Planchard John Geraghty Mike Bastoni Dr. Ken Berry

The Concept • Create a 6 week CAD unit that engages students and teachers in an integrated science, math and engineering activity. • Offer students and teachers an “Entry Level” Engineering Challenge that will help them develop the skills necessary to design and build complex mechanisms. • Aligned the CAD unit of study with national content standards in math, science and engineering education.

The Vision • CAD is a vehicle through which students and teachers can learn many other things. • Learning can be voluntary, exciting and engaging. Students are capable of deep learning when they are given the proper motivation and resources.

The Volume of a Cylinder Note: This is a very small cylinder. These are the dimensions of the holes in the GEARS-IDS 6 x 9 Plate R = 0. 095” H = 0. 090” V(cyl) = r 2 H R

The Volume of a Rectangular Prism 1” 1” 1” 2. 0” 3. 0” 2. 0” Volume = 12 in 3

Calculate the Volume of the 6” x 9” Plate Corner Radius =0. 250” = 3. 14 8. 688” Hole Dia. 0. 190” Plate Thickness 0. 090” 5. 688” Note: The solution to this problem is dependent on calculating the area accurately!
