Аннотация:
Simple Chemistry presents information and investigations on these six concepts: Objects can be described by the properties of the materials from whichthey are made. Substances can exist in different states — solid, liquid, or gas. Substances have characteristic properties. Mixtures can sometimes be separated into the original substances using characteristic properties. Elements are organized in the Periodic Table. When substances react chemically, they can form new substances. These resource books provide the busy teacher with science lessons that are appropriate and doable. Step-by-step lessons aligned with National Science Education Standards, make science relevant to real life. There are hands-on activities with student record sheets.
