Matter Lab Grades 6 to 8

Matter Lab Grades 6 to 8 is a 12-week chemistry course for middle schoolers that uses only kitchen materials. Students set up the Bench at home and keep a Bench Log. Week by week they learn what matter and atoms are and how to read the periodic table, how particles behave in solids, liquids and gases, how heat changes state, why things float or sink, how mixtures and solutions work, how atoms join into molecules, how to tell a physical change from a chemical change, why mass is conserved in a sealed bag, how a red cabbage indicator sorts acids from bases, why some reactions warm up and others cool down, and how natural resources become new materials. The course ends with a design project built, tested and improved at the Bench. Short daily lessons with checked answers, a hands-on Bench Lab each week and a Saturday Bench Day for the family. 100% free, start to finish.

• Explain what matter and atoms are and use the periodic table as the list of elements
• Use the particle model to explain solids, liquids and gases and how adding or removing heat changes state
• Measure and compare density, and separate mixtures and solutions with kitchen tools
• Build models of molecules and tell a physical change from a chemical change by the properties before and after
• Show that mass is conserved in a chemical reaction and sort kitchen liquids as acids or bases with an indicator
• Explain where synthetic materials come from and design, test and improve a device at the Bench
