  Lesson Plan: What is Density Mark as Favorite (2 Favorites)

  In this two-part lesson, students will learn about density through a teacher-led demonstration and a hands-on activity. The demonstration will give students the opportunity to observe the formation of a density tower made from common drinks. Students will then create their own density tower using simple ingredients, and then further investigate differences in density when solid objects are added to the tower.

  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.

  Demonstration: Investigating Gas Density Mark as Favorite (8 Favorites)

  In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.
