Science 4 Inquiry
All the Small Things
Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).

Elements, Compounds, and Mixtures
For this elements, compounds, and mixtures worksheet, students answer questions about the properties of elements, mixtures, and compounds. Students identify the physical changes that is made to a substance to determine if it is an element.

Pure Substances and Mixtures
Students compare and contrast the properties of substances and mixtures. For this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous mixtures.
