Do it yourself
Projects are a hands-on learning experience which should be included in the schools curriculum. We believe that DIY projects are a huge hit with children because most of them don’t fully grasp the idea of a science topic when they see it.
Abakcus is the collection of perfect source of DIY projects about mathematics and science.
