Classification of Matter
This is a great worksheet with an infographic to assist your students in categorizing matter into mixtures and non-mixtures. Information is given about the metric system of measurement. Your young students match 13 terms with their...
Science 4 Inquiry
States and Phases of Matter
Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.
