In the Proteins leveled reader, fundamental science concepts in chemistry are explained through simply written text and colorful, fun illustrations. Children will discover that a protein is a polymer-a long chain of atoms and molecules linked together. Atoms are the tiny building blocks that make up everything we touch, taste, smell, and see, and atoms link together to make molecules. Protein polymers fold into different shapes, including coils and sheets. The different shapes allow proteins to behave like tiny machines that do most of the jobs inside the body. A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 2-5, Interest Level 2-5.
