  Lab: Plop, Fizz Mark as Favorite (0 Favorites)

  In this lesson, students will react Alka-Seltzer tablets with water. By varying the temperature of the water, particle size of the Alka-Seltzer, and concentration of the Alka-Seltzer they can see the effect on the rate and strength of the chemical reaction.

  Lab: To What Degree Does it Matter Mark as Favorite (0 Favorites)

  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.
