Beskrivelse
A burning log, a rotting banana, and a rusting bicycle. These are examples of chemical changes. With this accessible narrative, readers are introduced to the basics of chemical changes. Easy-to-follow explanations cover matter, forms, properties, and changes. Further detail introduces how to make chemical changes and how to recognize them. Color photographs, fast facts, and an engaging activity expand and reinforce the newly learned ideas. This book supports Next Generation Science Standards, correlating directly with the NGSS Grade 2 standard to 'classify different kinds of materials by their observable properties.'
