Demonstration: Comparing Chemical Reactions Mark as Favorite (7 Favorites)
In this demonstration, the teacher will perform two chemical reactions, one will be between acetic acid (vinegar) and sodium bicarbonate (baking soda) and the other will be between Alka-Seltzer and water. Both reactions will produce gas and will be conducted in a Ziploc bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical change. Students will also determine that these are both endothermic reactions based on their observations.

Lab: Kitchen Reaction Mark as Favorite (18 Favorites)
In this lab students will observe an endothermic chemical reaction involving baking soda (sodium bicarbonate) and vinegar (acetic acid). Students will investigate the signs a chemical reaction has occurred (gas production, change in temperature). Students will perform the lab in an open system so they can see the change of mass due to gas production. This lab is a lead into the topic of conservation of mass. After the lab is completed, the teacher should do a demonstration of the exothermic reaction Hydrogen peroxide and potassium iodide.
