Researchers have found special atomic patterns called quasicrystals in 3D-printed aluminum alloys. Quasicrystals increase the strength of 3D-printed aluminum, the researchers discovered, making it ...

A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they have. A three-dimensional (3D) shape is a solid shape. 3D shapes have ...

A 2D shape could have line symmetry or rotation symmetry, or both! 3D shapes are described by their faces, edges and vertices. The faces can be the same shape or different, and a 3D shape could ...

Shapes and colors printables have been a key part of our early learning routine for years. As a homeschool mom, I’ve found that hands-on activities like these make it easier for kids to learn shape ...
