These channels make the cell membrane selectively permeable to various ions and other substances (like glucose). The selective permeability of the cell membrane allows the inside to have a different composition than the outside. For the purposes of nerve signals, we are interested in the following...

Glass is a unique substance that makes up materials all around us. It is very useful because of all its special properties. Learn about glass and...
We always like to include a bit of homemade slime science around here! Slime is an excellent chemistry demonstration and kids love it too! Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored wi...
Most jewelry is fashioned out of precious metals and jewels that are found buried in the earth, but pearls are found inside a living creature, an oyster. Pearls are the result of a biological process — the oyster's way of protecting itself from foreign substances. Oysters are not the only...
