The ChemCollective: Find Activities The ChemCollective is a collection of virtual labs, scenario-based learning activities, tutorials, and concept tests. Teachers can use our content for pre-labs, for alternatives to textbook homework, and for in-class activities for individuals or teams. Students can review and learn chemistry concepts using our virtual labs, simulations, and tutorials. In the game Mixed Reception, students use molar mass calculations, the scientific method, and basic knowledge of chemical reactions to solve a murder mystery. misterguch.brinkster.net/2009homework.html My 2008-09 Chemistry Homework Assignments! Because I know it’s sometimes handy for new (and not so new) chemistry teachers to see what other teachers are doing, I’ve decided to post, in chronological order, links to each of the homework assignments I gave my chemistry classes in the 2008-09 school year. As you can tell, I like to write my own questions as opposed to using the textbook. A couple of warnings: Because I use these worksheets myself and my students are very aware of my website, I have not included the answer keys to any of these worksheets. You’ll need the Adobe Acrobat Reader to access these files. 9/5: Safety and equipment homework sheet, safety contract 9/9: Scientific method worksheet. 9/11: SI units homework 9/15: Taking measurements at home homework, significant figures homework 9/17: Data Collection Review Sheet 9/19: Elements, Compounds, and Mixtures Homework Sheet. 9/23: Chemical and Physical Changes Homework 10/3: Average Atomic Masses Homework 10/28: “Periodic Table Fun!”
chempodcasts.com Off the Shelf Chemistry 1. The student will learn that chemicals are not something just found in laboratories. Our physical environment is composed of chemicals. Our bodies are composed of chemicals. Understanding the principles of chemistry helps us better understand our world. 2. 3. 4. 5. 6. This chemistry lab manual is designed to use consumer products for student chemistry experiments. Safety: All standard chemistry lab safety procedures must be strictly followed. Obtaining the Chemicals: Here is a list of where the chemicals for the experiments may be purchased. No Lab Tables Required: These experiments are especially suited to schools that have intensive scheduling. Background Information: As in any scientific endeavor, the first step is to gather information about the subject. Language Skill Building: Clear precise communication is a key to good science. Students often tell the teacher that they "know" something but can't put it into words. 1. 2. 3. 4. PDF lab for What is the Pop in Popcorn? 5. 6. 7.

CSIP Student Inquiry Projects - Tamara Hanna's CSIP Project Detection of Ions in Solutions Using Acid/Base Chemistry: A Quality Control Test Tamara Hanna 2004-2005 CSIP Fellow This curriculum unit allows students to become quality control testers and determine the amount of Ca2+ in Tang® and Mg(OH)2 in milk of magnesia through the use of acid/base titrations. Students will standardize three solutions that will be used in detecting the ions and will learn about titrations, indicators, pH and pH meters and the preparation of solutions, all included in a Regents curriculum. These experiments were designed for use by high school chemistry classes, either Regents or AP. This curriculum gives students a chance to see how solutions are analyzed in a chemical setting. The unit was developed/modified by Tamara Hanna, a graduate student in chemistry at Cornell University and was adapted from a lab written by Dr. Downloadable WORD files: Teacher's Guide Student Version

Making Measurement Meaningful or Why to Avoid Saying "Sig Figs" in Class. | JCE Chemical Education Xchange Every year when the day came to discuss the rules for significant figures in measurements with my classes I would write the rules on the board, we’d work through a couple examples, and I’d try to find a way to explain why we needed to use them when reporting measurements. This has never been my favorite topic to teach, mostly because I had a difficult time helping students see why these rules for measurement and reporting uncertainty were important. My students came to believe that sig figs were only important because there would be a grade penalty for not reporting to the right number of digits. This year I was determined to do a better job. The modeling curriculum has a sequence of activities I used to help illustrate how and why we report uncertainty in measurement. The sequence begins with practicing reading various devices – rulers, graduated cylinders, beakers, and burets. Why is a buret more precise than a beaker? What determines a device’s precision?
