This lab introduces students to the physical and chemical properties of the alkali metals. Students experiment to rank these elements in order of reactivity with water, reactivity with air, and softness. Indicator is used in the lab to help students visualize the speed of each reaction.
My students really enjoy the excitement this lab brings! In the end, they learn to predict the properties of elements below potassium on the Periodic Table and they understand why these elements are a "family." It's a lab they won't soon forget!
This product includes lab procedures, a student data sheet, and an answer key in WORD format, so that you can edit them.
