Acids and Bases

Erken Öğrenme

In the Acids and Bases leveled reader, fundamental chemistry science facts are explained through simply written text and colorful, fun illustrations. Children will discover that everything we see, touch, and taste is made of atoms. Atoms are the fundamental building blocks of matter and can link together to make molecules, which have different properties. Acids and bases are two types of molecules that have different properties. Sour molecules, such as those in lemons, are often acids; and molecules that are slippery, such as those in soap, are often bases. Acid molecules contain an "H" group made of one hydrogen atom. Base molecules contain an "OH" group made of an oxygen atom bonded to a hydrogen atom. "H" groups and "OH" groups give acids and bases their different properties. A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.
