Classroom Resources: Reactions & Stoichiometry
26 – 33 of 33 Classroom Resources
-
Exothermic & Endothermic, Chemical Change, Heat, Temperature, Classification of Reactions | Middle School, High School
Lab: Designing Exothermic and Endothermic Reactions
In this lab, students will design and test an experiment for producing either an endothermic or an exothermic reaction. The goal of the lab is for students to successfully construct a reproducible procedure for a reaction that either releases or absorbs thermal energy, and that can be supported with data.
-
Chemical Change, Chemical Change | High School, Middle School
Lab: Corrosion in Motion
In this lab, students will expose metal samples to various solutions and observe the amount of corrosion of a period of time.
-
Conservation of Mass, Chemical Change | High School, Middle School
Lab: Conservation of Mass
In this lab, students perform three simple experiments, recording the mass of a substance before and after a reaction. They then explain how the law of conservation of mass was not violated, even if the mass changed.
-
Chemical Change, Observations, Chemical Change, Reaction Rate, Interdisciplinary, Physical Change, Reaction Rate | Middle School
Lab: Chemical Weathering in Geology
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.
-
Chemical Change, Physical Change, Observations, Chemical Change, Interdisciplinary, Acid, Chemical Change | Middle School
Lab: Break It Down!
In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.
-
Chemical Change, Classification of Reactions, Oxidation, Reduction, Redox Reaction, Electrons, Electron Transfer, Ions, Observations, Inferences, Chemical Change | Middle School
Lesson Plan: One Tube Reaction
In this lesson, students will observe a chemical change involving oxidation and reduction.
-
Oxidation, Chemical Change, Oxidation, Reduction, Redox Reaction, Electrons, Electron Transfer | Middle School
Lesson Plan: Old Rusty
In this lesson, students will explore the concept of oxidation of metals by creating designs on fabric or paper using rusty objects.
-
Chemical Change, Observations, Mixture, Acids & Bases, Chemical Change | Elementary School, Middle School, High School
Demonstration: Inflating a Balloon with Chemistry
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.
