Demonstration: Plop & Fizz Investigation
In the demonstration the teacher will perform a reaction between water and Alka-Seltzer in order to generate the release of carbon dioxide. Students will observe the chemical reaction, while timing the release of carbon dioxide and observe 3 states of matter. This will be repeated 3 times, each time increasing the number of tablets used.

Demonstration: Apple's Oxidation
In this lab students will learn about the chemical reaction, oxidation, using apple wedges. They will apply different substances to a number of apple wedges to determine if these applications have any impact on the oxidation process. Students will also use a control sample so that they compare their results with an apple wedge that has not had any substance added to it. Students will measure and record the time it takes to see the changes to the apple which indicate oxidation. 3-46

Lab: To What DEGREE Does it Matter
In this lab the students will explore how factors such as temperature may influence chemical reactions. Students will use citric acid and sodium bicarbonate (Alka-Seltzer) and a catalyst (water) to induce a reaction at varying degrees. Observations will be made of the rate at which the reactions take place under these varying conditions. The students will make predictions of how the temperature of the water will affect the chemical reaction. They will use a stop watch to time the reaction between the Alka-Seltzer and the varying temperatures of water and graph their observations for analysis, they will compare data to deduce whether temperature has any influence during a chemical reaction.
