This is science made easy! You don’t have to be a rocket scientist to understand matter and energy. Our Combined resource includes all the important concepts in an easy-to-understand way using simple language and vocabulary. Discover what matter is, and isn’t. Learn about solids, liquids and gases, properties and changes in matter, and the difference between a mixture and a solution. Then, explore the invisible world of atoms and molecules. Young scientists will be thrilled to learn why they are mostly empty space, then on to the periodic table of elements followed by the study of energy. Our resources are jam-packed with experiments, reading passages, test prep, and activities all for students in grades 5 to 8. Eighteen color mini posters and answer key included. All of our content is aligned to your State Standards and are written to Bloom's Taxonomy and STEM initiatives.
