In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of...

Salt dissolves in water; oil does not. But why? You can think of that glass of water as a big, bumpin' dance party where the water molecules are always switching dance partners -- and they'd much rather dance with a salt ion. John...

This video is a lesson about the Earth's four systems: the geosphere, biosphere, hydrosphere, and atmosphere. It explains the characteristics and interactions of each sphere and how they are interconnected. The video also discusses...

This saltwater density tower experiment will help you and your children understand density better. Density is the mass of a material per unit volume, and it is a fixed number for each material. The density of water is 997 kg/m³;...

Fishes survive underwater pressure as they do not breathe through their lungs. Therefore, they do not have air pockets that can be compressed due to the high pressures. However, fish aren’t the only creatures found at such incredible...

The video is a lecture presentation on the topic of neutralization and salt production. The presenter discusses the reactions between acids and bases, and demonstrates examples of reactions between different types of acids and bases,...

In Water as a Natural Resource we are introduced to words such as habitat, ecosystem, watershed and estuary. Not only do kids learn that water exists everywhere on Earth, but that it is vital for life in plants, animals, and all other...
