Classification of Matter
Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...
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).
Teach Engineering
Chromatography Lab
Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places.
