If a material contains highly directional bonds, the shear modulus will increase and give a low Poisson ratio. A material is also considered hard if it resists plastic deformation. If a material has short covalent bonds, atomic dislocations that lead to plastic deformation are less likely to occur than in materials with longer, delocalized bonds.

Also materials for the development of the senses, mathematical materials, language materials, music, art and cultural materials, including more science-based activities like 'sink and float', Magnetic and Non magnetic and candle and air. [27] Activities in Children's Houses are typically hands-on, tactile materials to teach concepts.
She slows down and uses an upbeat voice because that's what helps kids learn best. "When you speak to a child naturally, actually, everywhere around the world, you do slow down. Your voice goes up.
