Classroom Resources: Reactions & Stoichiometry
1 – 18 of 18 Classroom Resources
Reaction Rate, Reaction Rate, Catalysts, Activation Energy | High School
The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach the topic of kinetics to your students.
Solubility, Reaction Rate, Balancing Equations, Stoichiometry | High School
In this lab, students will examine the reaction between citric acid and baking soda. They will analyze the chemical equation, balance it and calculate needed quantities of each reactant for a complete reaction. Based on their observations, students will determine if all reactants were completely used during the reaction.
Reaction Rate, Reaction Rate, Catalysts, Order of Reaction , Activation Energy, Rate Constant, Rate Determining Step | High School
In this lesson students explore reaction mechanisms and their connection to rate laws and energy profile graphs through a game, relay race, and finally a chemical demonstration.
Reaction Rate, Reaction Rate | High School, Middle School
In this simulation, students will have the opportunity to investigate several factors that can affect the initial rate of a chemical reaction. Students will have the opportunity to manipulate several variables including concentration, temperature, or surface area of the reactants as well as the addition of a catalyst during the simulation. These reaction rates will be compared to a controlled reaction. Students will interpret a simplified qualitative representation of the reaction as well as analyze corresponding data organized on a graph.
Precipitate, Reaction Rate, Reduction, Redox Reaction, Chemical Change, Oxidation, Solubility Rules | High School
In this lab, students investigate the use of milk of magnesia poultice to remove copper stains on masonry in copper architecture. They use chalk as the model for masonry, copper(II) chloride solution as a model for soluble copper and a freshly prepared slurry of copper phosphate as a model for a hard stain of copper on masonry. Through a series of investigations students have the opportunity to connect chemistry topics with real-world applications, such as environmental hazards, engineering practices of copper architecture, corrosion control, and structural protection.
Concentration, Reaction Rate, Reduction, Redox Reaction, Chemical Change, Oxidation, Beer's Law | High School
In this lesson students learn about factors affecting the rate of corrosion and evaluate the efficiency of different protective coatings to simulate products used in industry when building metal structures like ships or bridges.
Reaction Rate, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School
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.
Reaction Rate, Reaction Rate, Chemical Change | High School, Middle School
In this demonstration, students observe the effect of temperature, concentration, and particle size on the rate of a chemical reaction.
Reaction Rate, Reaction Rate, Catalysts, Combustion, Activation Energy | High School
In this series of demonstrations, students will be introduced to factors that affect the rates of chemical reactions. They will observe and record their observations, while also describing the rate-influencing factor for each demonstration as well as evidence supporting whether or not the reaction rate was increased or decreased by the factor.
Phase Changes, Reaction Rate, Reaction Rate, Chemical Change | Elementary School
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.
Solubility, Reaction Rate, Solute & Solvent, Physical Change | Elementary School
In this lab, students will investigate dissolving using M&M’s and will determine whether dissolving happens faster without assistance, or with the assistance of the tongue and teeth.
Observations, Chemical Change, Reaction Rate, Reaction Rate, Catalysts, Chemical Change | Elementary School
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.
Observations, Reaction Rate, Reaction Rate, Chemical Change | High School, Elementary School, Middle School
In this demonstration, students will see that different food dyes react with bleach at different rates.
Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School, Elementary School
In this lab, students will have the opportunity to construct a rocket, with the challenges of both designing it and preparing a chemical reaction for its “fuel” in order to propel the rocket over the furthest distance. Students will investigate available materials, quantities and ratios during allotted planning and testing phases. Student will record their plans, modifications and designs during the process. The lab will culminate with a competition amongst students to see whose rocket will travel the longest distance.
Reaction Rate, Reaction Rate, Acid Base Reactions | High School, Middle School
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.
Solubility, Physical Change, Phase Changes, Reaction Rate, Solute & Solvent, Molecular Motion | Elementary School
In this lesson, students learn that particles that make up matter are in constant motion.
Observations, Chemical Change, Interdisciplinary, Physical Change, Reaction Rate, Reaction Rate, Chemical Change | Middle School
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.
Reaction Rate, Reversible Reactions, Le Châtelier's Principle, Establishing Equilibrium | High School
In this lab, students will explore equilibrium using paper clips to mimic a chemical reaction.
