Lesson Plan: Redesigning a Car for the Environment Mark as Favorite (0 Favorites)
In this lesson plan, Chemland’s city public transportation board has requested the class to help them determine the direction the city should move towards in reducing the carbon footprint. Students will be divided into groups and will come up with proposals of how to reduce the carbon footprint from carbon dioxide released from vehicles. The groups will represent different ways to reduce the carbon footprint via an alternative fuel source or a new technology. They will debate their findings to determine the direction that the city council should move towards to reduce the carbon footprint.

Combustion | High School
Lab: Launching Rockets Mark as Favorite (0 Favorites)
In this lab, students create a stoichiometric mixture of hydrogen and oxygen gases to launch a soda bottle rocket.
-
Combustion | High School
Lab: Will O' The Wisp Mark as Favorite (0 Favorites)
In this lesson, students witness a chemical reaction that involves various states of matter and can include a stoichiometric problem.
-
Combustion | High School
Demonstration: Stop & Go Gases Mark as Favorite (0 Favorites)
In this demonstration, students will witness the ability of carbon dioxide to extinguish a flame and oxygen to feed a flame.
-
Combustion | High School
Demonstration: Liquid and Gas Burning Comparison Mark as Favorite (0 Favorites)
In this demo, students will witness the burning of a substance in its gas and in its liquid states. They will carry out the demonstrations themselves, and compare the results of the two reactions.
-
Combustion | High School
Demonstration: Grain Elevator Explosion Mark as Favorite (0 Favorites)
Download this demonstration in which students observe the combustion of lycopodium powder and discuss the effect of surface area on the reaction rate.
-
Stoichiometry | High School
Lesson Plan: How to do Stoichiometry Problems Mark as Favorite (0 Favorites)
In this lesson, students learn templates for performing stoichiometry problems. They then put the methods to the test with a practice worksheet.
-
Stoichiometry | High School
Lesson Plan: Stoichiometry Set-up Method Mark as Favorite (0 Favorites)
In this lesson, students will learn how to follow a process of visual cues in combination with a step-by-step problem solving method for different types of stoichiometric problems. This method can be particularly beneficial for students who struggle with completing multi-step calculations.
-
Stoichiometry | High School
Lesson Plan: Stoichiometry of Air Bags Mark as Favorite (0 Favorites)
In this lesson, students will be introduced to the concept of gram to gram stoichiometry calculations. Students will be guided through a scenario regarding air bags and will be tasked with calculating the amount of gas (NaN3) that must be used to inflate a vehicle air bag to the correct size. Follow-up practice problems are also provided.
-
Stoichiometry | High School
Lab: Baking Soda Stoichiometry Mark as Favorite (0 Favorites)
In this lab, students will decompose baking soda and use stoichiometry to determine the proper balanced chemical equation of its decomposition.
-
Net Ionic Equation | High School
Lab: White Lab Mark as Favorite (0 Favorites)
In this lab, students use molarity concepts to review limiting reactant concepts mathematically, conceptually, and graphically. They can then carry out a follow up investigation to identify an unknown using concepts learned in the first investigation.
-
Conservation of Mass | High School
Lab: Kitchen Reaction Mark as Favorite (0 Favorites)
In this lab students will observe an endothermic chemical reaction involving baking soda (sodium bicarbonate) and vinegar (acetic acid). Students will investigate the signs a chemical reaction has occurred (gas production, change in temperature). Students will perform the lab in an open system so they can see the change of mass due to gas production. This lab is a lead into the topic of conservation of mass. After the lab is completed, the teacher should do a demonstration of the exothermic reaction Hydrogen peroxide and potassium iodide.
-
Conservation of Mass | High School
Lab: Matter Matters Mark as Favorite (0 Favorites)
In this lesson, students will investigate the Law of Conservation of Mass.
-
Conservation of Mass | High School
Lab: Soap or Fuel Mark as Favorite (0 Favorites)
In this lab, students will transform vegetable oil into a soft soap and into biodiesel fuel. The two reactions emphasize that the products of a chemical reaction are under the control of the chemist. By noting the relationship of the reaction product to the reactants, students will gain a deeper understanding of the law of conservation of matter.
-
Conservation of Mass | High School
Lab: Reactions of Copper Mark as Favorite (0 Favorites)
In this lab, students will convert copper metal into different copper compounds and then back to copper to illustrate conservation of matter.
-
Balancing Equations | High School
Activity: Snowman Challenge Mark as Favorite (0 Favorites)
In this activity, students practice completing and balancing chemical equations with a partner.
-
Balancing Equations | High School
Activity: S'more Stoichiometry Mark as Favorite (0 Favorites)
In this activity, students determine the number of graham crackers and chocolate pieces required to complete a “reaction” with a given quantity of marshmallows (the limiting reactant). They then use the same thought process with a problem involving a real chemical reaction.
-
