Properties of Metals

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating. The alloy station is a matching game where elements are combined to make alloys, and the other three are hands-on chemistry experiments. A final adult-led demonstration related to fireworks provides a dramatic conclusion to the lesson. This lesson-plan lays out a schedule for a full hour, but each activity station requires only about 10 minutes to complete. If time is limited, the activities can be used independently as mini-lessons or demonstrations. Safety note: the Metal Plating station involves lye and an open flame; adult supervision is recommended. [Activity is publicly available through a web crawler capture on Archive.org.]
