Classroom Resources: Reactions & Stoichiometry
1 – 12 of 12 Classroom Resources
Conservation of Matter, Classification of Reactions | Middle School, High School
In this lesson, students will be introduced to five basic types of chemical reactions through a metaphor about a high school dance. Afterwards students will complete research to fill out a graphic organizer and reinforce the introductory information.
Conservation of Matter, Stoichiometry, Limiting Reactant | High School
In this lesson, students will identify limiting reagents (and the amounts of product produced) using the mole of reaction concept. This approach is designed to focus on calculations related to limiting reactant after a conceptual understanding of what a limiting reactant is has already been established.
Observations, Separating Mixtures, Physical Properties, Conservation of Matter | Elementary School
In this lesson the students will become familiar with some ways that chemistry is present in their everyday lives. The teacher will read a book and show a short video about how a plastic bottle is made. Following these activities, students will interact with a variety of materials made of plastic, ultimately organizing them according to the recycling code printed on the bottom of each or by physical properties. Finally students will collect data and have an opportunity to construct a graph based on their data.
Renewable Energy, Interdisciplinary, Conservation of Matter, Matter | Elementary School
In this lab students will explore ways to conserve natural resources. They will then have the opportunity to create their own recycled paper that can be used in the classroom.
Phase Changes, Conservation of Matter, Polymers, Chemical Change | Elementary School
In this lesson, students explore the science behind chemical reactions as well as the processes used by chemical engineering principles to develop new materials. The idea that mixing two substances can result in an explosion, the release of gas, and the formation of an entirely new substance is both fascinating and mysterious to most young students.
Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Elementary School, Middle 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.
Observations, Separating Mixtures, Chemical Change, Conservation of Mass, Lab Safety, Conservation of Matter, Balancing Equations, Percent Yield, Conservation of Mass, Classification of Reactions, Accuracy, Chemical Change, Chemical Properties, Conservation of Matter, Error Analysis | High School
In this lab, students will convert copper metal into different copper compounds and then back to copper to illustrate conservation of matter.
Elements, Identifying an Unknown, Conservation of Matter, Culminating Project, Chemical Change | Middle School
In this lab, students will identify an unknown gas based on experimental evidence.
Elements, Interdisciplinary, Molecular Formula, Conservation of Mass, Conservation of Matter, Molecular Structure, Balancing Equations, Reversible Reactions, Chemical Change, Matter, Photosynthesis, Monomer | Elementary School
In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.
Pressure, Conservation of Matter | Elementary School
In this lab, students will conduct a chemical reaction that will be used to launch a rocket.
Observations, Chemical Change, Conservation of Mass, Conservation of Matter, Balancing Equations, Conservation of Mass, Chemical Change, Matter, Conservation of Matter, Predicting Products, Experimental Design | High School
In this lesson, students will investigate the Law of Conservation of Mass.
Polyatomic Ions, Chemical Change, Conservation of Mass, Precipitate, Conservation of Matter, Balancing Equations, Conservation of Mass, Chemical Change, Conservation of Matter | Middle School, High School
In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
