Classroom Resources: Reactions & Stoichiometry
51 – 61 of 61 Classroom Resources
Introduction, Conservation of Mass, Balancing Equations, Conservation of Mass, Limiting Reactant | High School, Middle School
In this lesson students, through their physical movement, will model the law of conservation of mass during a chemical reaction. Students will also explore the concepts of limiting and excess reactants as well as balancing a chemical equation. Through this activity they also develop a means of representing particles at the molecular level.
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.
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.
Polymers, Molecular Structure, Polymers, Chemical Change, Molecular Structure , Chemical Bond, Monomer, Monomer | Middle School
In this lesson students will use lab activities and discussion to explore polymers and their use in 3D printing, with an emphasis on the benefits of 3D printing in automotive manufacturing.
Polymers, Polymers, Chemical Change, Chemical Bond | High School, Middle School
In this demonstration, students will observe the process of making a polymer, casein plastic, from the casein protein found in milk.
Chemical Change, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules | Middle School, High School
In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.
Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Middle School, Elementary School
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.
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.
Density, Chemical Change, Density, Chemical Change | High School, Middle School, Elementary School
In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.
Observations, Phase Changes, Combustion, Chemical Change | Middle School, Elementary School
In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.
Observations, Chemical Change, Acids & Bases, Chemical Change, Mixtures | High School, Middle School, Elementary School
In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
