Molecular Kit

thingiverse

This model was created for the MakerEd Challenge. With this kit, students and teachers can assemble several different molecules pair to help learning in the classroom. Furthermore, it is also possible to explain the molecular geometry, showing the angles between the bonds. Print Settings Printer Brand: RepRap Printer: Prusa i3 Resolution: 0.2 Infill: 30% How I Designed This These objects are very simple, I used Tinkercad to create them with a few geometric shapes and some intersections. Ball with an intersection I did some balls and multiple cylinders positioned them in the right position with the exact angle using the rotation tool. In the spheres in the inspector I I configured as 'Color' and the cylinders I I configured as 'Hole' after group these components I have intersections. ball with three intersections Bond with two intersections Project: Molecular Kit Objectives The objective of this kit is to help students and teachers in the classroom, showing some molecules physically and how the links in addition to the students to learn the amount of necessary connections and the angle between them. Audiences high school; chemical classes; entrance exam preparation courses; home schooled students; Preparation Students should know a little chemistry, molecules, chemical composition and molecular geometry. Step 1: Research about molecular geometry I studied molecular geometry in high school, but I had to give a revised to remember all connections, their names and angles. Step 2: Create the model In Tinkercad I created models using geometric shapes and their intersections. The challenge here is to position the links at the correct angle. The way 'linar' is the simplest, it 180 ° between its links. The way 'trigonal planar' is 120 ° between its links. The way 'tethahedral' has 109.5 ° between all its connections. The form "trigonal bipyramidal 'has three connections 120 ° in the middle and 180 ° between the two other connections. The way 'octahedral' has 90 ° of all your calls. Results After printing the students should be able to mount several different molecules and understand how the molecular geometry.
