These high school chemistry worksheets are full of pictures, diagrams, and deeper questions covering all aspects of chemical bonding! Using these unit pages, students can practice writing Lewis structures (8 pages of them, covering each type separately, like expanded octets, double/triple bonds, and ionic!) Students will practice skills like identifying formal charges, molecular shapes from the Lewis structure, and identifying the intermolecular and intramolecular forces at play. There are two real-world type problem pages where students identify types of solids.
In several places in this unit, I've included easier and more difficult pages to allow teachers to really differentiate. For example, I have two different molecular shape determination pages, but one page only asks students molecules that do not have expanded octets. This unit is designed to help students practice these skills that are important for the rest of the year in chemistry.
This unit contains these pages:
1. Valence Electron Determination Practice
2. Ionic or Covalent Bonds: Determination from Electronegativity Differences
3. Electron Dot Diagrams: Atoms and Ions (Free Sample)
4. Electron Dot Diagrams: Binary Ionic Compounds
5. Electron Dot Diagrams: Simple Covalent Compounds
6. Electron Dot Diagrams: Double/Triple Bonds
7. Electron Dot Diagrams: Polyatomic Ions #1 (without expanded octets)
8. Electron Dot Diagrams: Polyatomic Ions #2 (with expanded octets)
9. Electron Dot Diagrams: Multiple Central Atoms
10. Electron Dot Diagrams: Incomplete Octets and Expanded Octets
11. Formal Charge Calculation Practice
12. Identify the Molecular Shape (Simpler Diagrams)
13. Molecular Shape 1 (Identify molecular shapes from Lewis structures, but only asks for linear, bent, trigonal planar, trigonal pyramidal, and tetrahedral)
14. Molecular Shape 2 (Identify from Lewis structure, more complex)
15. Draw the Lewis Structure AND Identify the Shape
16. Drawing Dipole Moments (and label as polar or non polar)
17. Intramolecular and Intermolecular Forces
18. Mysteries from Mars: Solid Identification from Properties
19. Classifying Solids: Intermolecular and Intramolecular Forces Plus Data
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!
