Combustion, Chemical Change, Balancing Equations, Reaction Rate, Conservation of Mass, Conservation of Matter, Stoichiometry, Limiting Reactant, Chemical Change, Conservation of Matter, Conservation of Mass, Graphing, Error Analysis, Accuracy, Observations, Inferences, Interdisciplinary, Reaction Rate, Catalysts, Measurements, Mole Concept | High School
In this lesson, students will learn about air pollution and some steps toward mitigating it. First, they will burn a candle and measure its mass and the concentration of CO2 over time. Students will discuss which data set they have more confidence in and why and then use stoichiometry to predict outcomes. Next, students explore incomplete combustion in a model-based worksheet that shows how a lack of O2 in the burning of fuels can produce air pollution. Students work together to interpret the models, define terms, and draw conclusions. Lastly, students work in groups using Lego models to illustrate how a catalytic converter works. They race “Nature” against catalysts “Palladium,” “Platinum,” and “Rhodium” to see what breaks down air pollution molecules fastest.
Limiting Reactant, Stoichiometry, Balancing Equations, Conservation of Mass, Conservation of Matter, Combustion, Conservation of Mass, Conservation of Matter | High School
In this activity, students will use an animation to visualize on the particulate level what happens in a limiting reactant problem. Assembling a bike is used as an analogy to introduce the concept of limiting reactant, and then the balanced equation of the combustion of methane is used in four quantitative examples to show what it means for a chemical to be a limiting reactant. The concept of the conservation of mass is also demonstrated by calculating masses from the mole quantities of the reactants and products.
Classification of Reactions, Conservation of Matter | 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.
Limiting Reactant, Stoichiometry, Conservation of Matter | 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.
Separating Mixtures, Observations, 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.
Conservation of Matter, Matter, Interdisciplinary, Renewable Energy | 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.
Polymers, Chemical Change, Conservation of Matter, Phase Changes | 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, Reaction Rate, Acid Base Reactions, Chemical Change, Conservation of Matter | 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.
Conservation of Mass, Conservation of Matter, Chemical Change, Classification of Reactions, Percent Yield, Balancing Equations, Error Analysis, Accuracy, Chemical Change, Chemical Properties, Conservation of Mass, Conservation of Matter, Observations, Separating Mixtures | High School
In this lab, students will convert copper metal into different copper compounds and then back to copper to illustrate conservation of matter.
Chemical Change, Conservation of Matter, Identifying an Unknown, Culminating Project, Elements | Middle School
In this lab, students will identify an unknown gas based on experimental evidence.
Conservation of Matter, Chemical Change, Photosynthesis, Balancing Equations, Reversible Reactions, Molecular Formula, Molecular Structure, Conservation of Mass, Interdisciplinary, Matter, Elements, Monomer | Elementary School
In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.
Conservation of Matter, Pressure | Elementary School
In this lab, students will conduct a chemical reaction that will be used to launch a rocket.
Conservation of Mass, Matter, Conservation of Matter, Conservation of Matter, Conservation of Mass, Balancing Equations, Chemical Change, Predicting Products, Experimental Design, Chemical Change, Observations | High School
In this lesson, students will investigate the Law of Conservation of Mass.
Balancing Equations, Conservation of Mass, Conservation of Matter, Conservation of Matter, Chemical Change, Chemical Change, Conservation of Mass, Polyatomic Ions, Precipitate | 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.
