Educational Objective - “I Wonder…” Statements - Guided ReadingEducational Objective: Students should understand the importance of thermochemistry. Thermochemistry revolves around the energy (heat) associated with reactions and other materials. This area of chemistry has a variety of terms and applications that should be understood before embarking on college-level chemistry courses. Terms such as temperature, specific heat, calorimeter, and enthalpy are commonly used in laboratory experiments. These terms also relate to common items that students may see on a daily basis. Warm hands and the number of calories in food are linked to thermochemistry. What two places can cause students difficulty while reading? The introduction of the specific term Have any of you wondered about the magic that happens in a hot hand? The hot hand is a small pouch containing mysterious elements that combine to trigger a heat-producing reaction. There is a specific area of chemistry that studies the heat associated with reactions, and today we begin our journey by learning about this form of chemistry called thermochemistry! Thermochemistry is a fascinating area of chemistry that contains new terms and ideas that must be understood in order to proceed with the mathematical applications of thermochemistry. We'll create "I wonder..." statements to help you explore these new terms as we read the document. So let's say I read the section on heat and temperature. I learned that heat and temperature are related, but they are different quantities. This idea of difference leads me to think about how the two terms are related but different, so I began writing a statement that expresses my curiosity about these terms and will hopefully find a response in the text or during a class discussion. I wonder… how heat and temperature are integrated in chemistry. I will now go ahead and read the next section of the text to hopefully respond to my statement. While reading I came across the term "specific heat" and the definition stated that specific heat is the amount of energy required to raise the temperature of one gram of a substance by one degree Celsius or one kelvin . I learned that specific heat is a value needed to increase the temperature of a gram by one degree! Since I found my answer in the text, I will write this definition by my statement, so that I can discuss it later in
