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.

Lesson Plan: Designing & Engineering a Fast Defroster
In this activity students use their understanding of energy transfer to “design a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.” And “evaluate a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.” The real world problem is to help a cook who is trying to make a meal, but realizes some of the ingredients are frozen and must be thawed before he can begin.

Lab: Cool Science: Building and Testing a Model Radiator
In this lab students construct a model of a car radiator to investigate parameters that lead to efficient cooling. Students investigate multiple variables as they experiment with various radiator designs. This lesson focuses on thermochemistry calculations and engineering practices.

Lesson Plan: Particle Modeling of Hand Warmers
In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a physical process, such as the crystallization of a solid from a supersaturated solution.
-
Phase Changes, Physical Change, Observations, Temperature | Elementary School, Middle School
Lab: Condensation
In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

Simulation: Energy Changes in Chemical Reactions
In the November 2016 simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Students will have the opportunity to compare how energy is absorbed and released in each reaction, and will make a connection between the standard energy diagrams associated with each reaction type.

Simulation: Heating Curve of Water
In the May 2015 issue, students explore the heating curve for water from a qualitative and quantitative perspective. Students compare illustrations of each physical state depicted on the curve and calculate the energy required to transition from one state to another.
