Microscopes is a simply written, colorful introduction to an important and commonly used scientific instrument. Young readers will learn that some objects are too small to be seen with the eyes alone, for example, red blood cells and atoms, but a microscope can be used to magnify them to a size that can be seen. A light microscope has lenses for magnifying the sample, a stage to hold the sample, and a light to illuminate it. Red blood cells can be seen with a light microscope. There are also other types of microscopes that can be used to see smaller things, even atoms. Some microscopic images are shown.A pronunciation guide of scientific terms is included. 24 pages full of engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.

In the Acids and Bases leveled reader, fundamental chemistry science facts are explained through easily understood text and colorful illustrations and photographs. Children 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 that 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, while 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. Reading Level 1-3, Interest Level 2-5. Lexile measure 450L.

In the leveled reader Baseballs, Hockey Pucks, and Busy Ants: A Look at Linear Motion, fundamental scientific concepts in physics are explained through simply written text and colorful, fun illustrations. Young readers discover that any object moving in a straight line has linear motion. When moving in a straight line, objects such as hockey pucks, baseballs, and bicycles have linear motion. Living things such as ants, snails, horses, and people have linear motion when they are moving in a straight line. Children are encouraged to think of other examples of linear motion.A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.
