  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.

  Combustion, Chemical Change, Catalysts, Acid Base Reactions, Chemical Change, Balancing Equations, Classification of Reactions, Observations, Chemical Change | High School, Middle School

  Demonstration: Stop & Go Gases Mark as Favorite (7 Favorites)

  In this demonstration, students will witness the ability of carbon dioxide to extinguish a flame and oxygen to feed a flame. They will also be introduced to the concept of catalysts. This demonstration could also be used as an opportunity to practice writing and balancing equations and classifying chemical reactions.

  Reaction Rate, Experimental Design, Scientific Method, Observations, Chemical Change | High School, Middle School

  Lab: Reaction Rate Mark as Favorite (22 Favorites)

  In this lab, students will explore factors that effect reaction rate and develop a general statement that describes how the factors (temperature, particle size, and concentration) effect the rate based on experimental data. This is an inquiry-based activity.

  Lab: Chemical Weathering in Geology Mark as Favorite (1 Favorite)

  In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

  Lesson Plan: Catalysis & Catalytic Converters Mark as Favorite (11 Favorites)

  In this lesson students will be introduced to catalysts while expanding their knowledge of chemical reactions and stoichiometry. They will first learn about catalytic converters and then be challenged to create the best “catalytic converter” of hydrogen peroxide to oxygen gas in an inquiry-based activity.

  Lab: Bath Bomb Chemistry! Mark as Favorite (28 Favorites)

  In this lab, the students will work in cooperative groups to investigate how to make a scented, effervescent bath bomb and explore the chemistry needed to create them. Groups will test a variety of different variables in order to compare the reaction rate of each sample. Students will use the results to determine which variables are optimal for making and using bath bombs.

  Solubility, Saturated/Unsaturated/Supersaturated, Mixtures, Reaction Rate | High School

  Lab: Rate of Solution Mark as Favorite (21 Favorites)

  In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.
