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.

Activity: Simulation Activity: Energy Changes in Chemical Reactions Mark as Favorite (96 Favorites)
In this simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Through the use of this simulation students will have the opportunity to compare how energy is absorbed and released in each reaction. Additionally, students will make a connection between the standard energy diagrams associated with each reaction type.

Lab: Investigating Condensation Mark as Favorite (8 Favorites)
In this lab, students will explore the phase change of condensation and determine whether this process is endothermic or exothermic. Students will then investigate how water vapor condenses, what effect surrounding temperature has on the rate of condensation, and what is happening to the molecules when they condense.

Demonstration: Introducing Limiting Reactants Mark as Favorite (15 Favorites)
In this demonstration, the teacher will perform a series of reactions between acetic acid--vinegar-- and varying amounts of sodium bicarbonate --baking soda--in order to inflate several Ziploc bags. Students will observe the reactions and analyze the quantities of reactants used as well as the results in order to understand the concept of limiting reactants. Students will also determine if the reaction is an endothermic or exothermic process 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.

Lab: Chemistry is Cooler Stress Test Challenge Mark as Favorite (66 Favorites)
In this lab, students will design and build a device capable of insulating an ice cube submerged in boiling water for two minutes. In this open-ended inquiry based activity, students will be required to critically think about structure and function of the materials they wish to use to build a device to solve a complex real-world problem. Students must consider the thermal properties of the materials, density, and the need to form a non-permeable barrier between the ice cube and the boiling water.
