These high school chemistry worksheets are full of pictures, diagrams, and deeper questions covering reaction rates! This unit is meant to cover the concepts and calculations surrounding activation energy, free energy diagrams, reaction mechanisms, rate laws, and rate constants!
This unit is designed with the more advanced (mainly pre-AP and AP Chemistry) students in mind, as most regular level chemistry students do not go very far with equilibrium.
This unit contains these pages:
1. Reaction Rates and Equilibrium Graphs
2. Changes in Reaction Rates
3. Free Energy Diagrams and Activation Energy
4. Effects on Reaction Rate at Molecular Level
5. Elementary Reactions and Reaction Mechanisms
6. Rate Law and Rate Constant 1
7. Rate Law and Rate Constant 2
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!
