In this activity, students walk around a room and view mini-posters (8½ by 11) that list
the common name (if applicable), chemical name, chemical formula, and facts about ionic compounds used in daily life. Each mini-poster is missing either a chemical name or chemical formula. As students visit each poster, they will record the information given and determine the missing name or formula for the compound. In the example below, students would determine the chemical name for salt.
Common Name: Salt
Chemical Formula: NaCl
• Used to flavor and preserve food.
• Used to create a saline solution.
o Saline solutions are commonly found in eye drops.
o Saline solutions are administered at hospitals through an IV when a person is dehydrated.
Example Student Chart:
Item #1: Salt - sodium chloride - NaCl - Used to preserve food & used in IV's
The goal of this activity is to provide a review of ionic naming and formulas at the end of the unit as well as introduce students to the practical use and applications of ionic compounds. 23 compounds are discussed: 1 example and 22 items for student practice. 8 min-posters contain pictures. The remaining 15 mini-posters require the teacher to obtain items. A list of suggested items is available in the Materials List. In the example above, the teacher would need to obtain and provide salt, a canned good with salt listed as an ingredient, and/or an eye wash bottle with ingredients listed. These items would be placed at the station with the salt poster. The Materials List provides various suggestions for items that can be used to represent each compound. If a picture is worth a thousand words, then a real-life item is worth at least three thousand words . The purpose of utilizing items at the stations is to help students connect ionic compounds to application in life.
Students will be able to…
• Name ionic compounds.
• Write chemical formulas for ionic compounds.
• List common uses for ionic compounds.
• Ionic Compounds in Daily Life! – Teacher Directions
• Ionic Compounds in Daily Life! – Materials List
• Ionic Compounds in Daily Life! – Item Master List
• Ionic Compounds in Daily Life! – Student WS
• Ionic Compounds in Daily Life! – Student WS - KEY
• Ionic Compounds in Daily Life! – Posters
Additional Required Materials:
• 15 additional items will be required. Options for items are given in the Materials List. Items can be found in a local pharmacy, grocery store, or hardware store.
(Note: Use packaging or empty/used bottles that still contain the ingredient list. For example, an empty bottle of laundry detergent or make-up would be perfect.)
