    Looking for a STEM project with a WOW factor? This engineering project is it.. see the hypercube left! Discover how the outer wand structure affects the shape of the inverted bubbles that form. This project teaches about tensile structures by building 3D bubble wands with Geoshapes squares, triangles and pentagons then dipping them in bubble solution to make inverted tensile bubbles. This simple demonstration will introduce a complex engineering concept to children visually. Set includes 60 Geoshape squares, 54 Geoshape triangles, 30 Geoshape pentagons and Professor Art Johnson's book 'Build Up To Bubbles: Geometry Made Interesting With 3D Geoshapes/Grades 5-10'. The Bubble Geometry Class Set provides an excellent introduction to geometry concepts such as the Platonic solids, Euler's law and non-Euclidian geometry. Just click the Geoshapes together to form the 3D models and dip them into the bubble solution. Suitable for grades 5-10.
