Chemistry Unit 11: Thermochemistry and States of Matter Homework Pages
These high school chemistry worksheets are full of pictures, diagrams, and deeper questions covering all aspects of thermochemistry and states of matter! This unit is meant to cover the basics of enthalpy, specific heat problems, standard heat of formation, phase diagrams, time and temperature graphs, Hess' Law, and even a Born-Haber diagram!
This unit contains these pages:
1. Systems and Thermodynamics
2. States of Matter and Changes
3. Time and Temperature Graphs
4. Phase Diagrams
5. Enthalpy Picture Problems: What’s the Formula?
6. Enthalpy Picture Problems: Write the Picture Steps
7. Melting and Evaporating Problems
8. Enthalpy and State Changes Problems
9. Specific Heat and Enthalpy Changes
10-11. What will the temperature be? (Parts 1 and 2)
12. Mystery Metal Enthalpy Changes
13. Calorimeter Energy Loss/Gain
14. Coffee Cup Calorimeter Problems
15. Elements and Standard Heat of Formation
16. Standard Enthalpy of Combustion
17. Hess’ Law: 2 Equations
18. Hess’ Law: 3 Equations
19. Enthalpy Diagrams
20. Born-Haber Cycle: Hess Application
Each page will be unique. Each is designed to roughly cover the material that I would teach in an hour long class period. These are terrific for daily homework assignments because they don’t take too long to complete.
These pages have been carefully designed in Illustrator. I have created a unique set of questions to help students to review material taught in class and think deeper about the material. Many of the pages ask students to highlight or color something, to identify items in a diagram, to match related concepts, or interact with a topic in a new way. Many of the pages ask students to connect more than one concept; they are intended to help students see the bigger picture in each unit. A few pages ask students to use the internet to do a little research.
If you own any of my other resources, don’t worry about repeat pages. These homework pages are truly unique and separate from my activities. These homework pages will truly complement any activities or resources you already have or use in your class.
Homework Page Implementation Suggestions:
* First of all, I don’t grade it. I learned in my early teaching years that when I grade homework, I am rewarding students who copied off of their one studious friend the period before my class, and I am penalizing students who have limited educational time outside of school. I often give time at the end of the period to work on “homework” pages. Often, I start off the next day’s class with the answer key projected onto some sort of screen (ELMO or projector) so that students can check their answers as they walk in. My students know that they will do better in my class if they do the homework and I care about effort more than being correct.
* Answer keys are included (for almost all of the pages, where it makes sense to have an answer key). I designed these pages to be pretty simple to grade, if you want to do that.
* In my time as a teacher, I have noticed that for some reason, homework assignments that have more than one side of a page are just neglected by students. If I hand out a one sided homework page and tell them, here’s your homework, they say, yay, it’s just 1 page! They will often at least start it if not finish it before the end of the day. I really think there is a psychological barrier to starting an assignment with two sides. Call me crazy, but test it out! Try giving my homework assignments and watch your class actually do their homework!
* A way to save paper would be to print all of the homework assignments and copy them as a packet. This is great to give students all at once in the beginning of the unit, so they have every page in advance, which works great if they’re absent!
