Simple model to demonstrate interaction between Sun, Earth and Moon. Here is the short assembly video Print Sun in Orange color, Earth in Blue color and Moon in white color. 2mm and 3mm metal rod is used as an axle. Support is required…
Concepts of Longitude and latitude with respect to center of the Earth can be explained nicely with the help of this model. Norther Hemisphere is broken into two parts. It represents slice from 0 longitude to 73 E. When printed on the…
Conic sections are great way to visualize various cuts given to a solid cone. This 3D printed model can be printed easily with no support. Here is the reference video of the same.
We use containers of different shapes and sizes to measure ,transfer as well as store things. Amount of quantity stored depends on the shape as well. We will consider 3 shapes Sphere, Cylinder and Cone . These are hollow shapes so that we…
Center line on this rectangular bar is drawn with the help of parallelogram. Normally we will use a ruler to mark center points at a couple of locations. Joining these two points will give us a center line. We can instead use…
Longitudinal view of the Earth enables student to map how hours are derived on the equatorial sundial. There are 24 petals or divisions on the sphere with spacing at 15 degrees each. This sphere can also be used to represent two…
A cardioid is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed circle of the same radius. I decided to use gears instead of plain round discs to draw a cardioid These two gears have the same…
Use triangle to find out how levelled horizontal surface is ! Spirit level, a tool designed to help us decide if a surface is perfectly horizontal or not . Can we achieve a similar result with this ? You must have thought it's a simple…
