Molecular Kit

thingiverse

This model was designed specifically for the MakerEd Challenge. With this kit, students and teachers can assemble a variety of molecules in the classroom to enhance learning. Furthermore, it is also possible to explain the molecular geometry by showing the angles between bonds. Print Settings Printer Brand: RepRap Printer: Prusa i3 Resolution: 0.2 mm Infill: 30% How I Designed This These objects are extremely simple, and I used Tinkercad to create them using a few basic geometric shapes and some precise intersections. I created balls with multiple cylinders positioned in the exact right position at precise angles using the rotation tool. In the inspector, I configured the spheres as 'Color' and the cylinders as 'Hole.' After grouping these components, I enabled intersections. Project: Molecular Kit Objectives The main goal of this kit is to help students and teachers in the classroom by physically showing some molecules and illustrating how links are connected along with the necessary connections and angles between them. Audiences High school students; Chemical classes; Entrance exam preparation courses; Home-schooled students; Preparation Students should have a basic understanding of chemistry, molecules, chemical composition, and molecular geometry. Step 1: Research about Molecular Geometry I studied molecular geometry in high school, but I had to review the connections, their names, and angles all over again. Step 2: Create the Model In Tinkercad, I created models using geometric shapes and precise intersections. The key challenge here is positioning the links at the correct angle. For example, in a 'linear' molecule, the links are at 180 degrees to each other. In a 'trigonal planar' molecule, there's a 120-degree angle between the links. In a 'tetrahedral' molecule, all connections are at 109.5 degrees apart. A 'trigonal bipyramidal' molecule has three middle connections at 120 degrees and two outer connections at 180 degrees. An 'octahedral' molecule has 90-degree angles between all its links. Results After printing, students should be able to assemble various molecules and understand how molecular geometry works.
