Periodic Trends and Properties of Elements—Super
Chemical Demonstration Kit
Safe Swimming with Sodium is safe yet spec- tacular demonstration of alkali metals reacting with water. Pour water then mineral oil into a graduated cylinder. Add a small pre-cut piece of sodium, and it falls through the top layer of mineral oil, reacts with the water at the inter- face and is forced back into the mineral oil layer, then the process begins again. Teacher Demonstration Notes included.

Safe Swimming with Sodium—
Value Laboratory Kit
This microscale experiment identifies trends in reactions and solubility of the alkaline earth metals. Students compare reactions to discover trends within a group and across a period, then study solubility patterns of compounds and use that to identify an unknown. Includes reproducible student handouts, detailed teacher notes and all neces- sary chemicals and consumables. Super Value Kit is complete for 5 classes of 30 students working in pairs.

Periodic Table Basics—Student Laboratory Kit
In this kit, students first gather information and complete the ultimate element crossword puzzle to prepare for two hands-on labs compar- ing alkaline earth metal reactivity and investigating the solubility of alkaline earth metal cations. Includes chemicals, reusable pipets, periodic tables, detailed Teacher Notes and reproducible student handouts. Complete for 24 students working in pairs.

FLINN SCIENTIFIC I THE PERIODIC TABLE
All in the Family—Periodic Trends Demonstration Kit
This inquiry-based demonstration explores similarities and differ- ences in the reactivity of halogens. Freshly prepared dilute aqueous solutions of chlorine, bromine and iodine are mixed in capped
glass bottles pair-wise with chloride, bromide or iodide ions in a two-phase solvent system. Students rank the halogens from most to least active and discover the periodic trend in their reactivity. Teacher Demonstration Notes and student worksheet included.
