Stoichiometry and Moles—Laboratory Kits
Rockets, Reactions and Ratios—Guided-Inquiry Kit
By: Deborah Maloney
Hollis Brookline H.S., Hollis, NH
Take the common reaction of baking soda and vinegar to new heights in this exciting STEM inquiry-based competition! The goal is to find the right ratio of rocket mass to baking soda mass to propel a paper rocket a vertical distance of 1 meter.
Students design and construct a paper rocket to contain a film canister “fuel tank.” Next, they determine the optimal amount of baking soda for a given amount of vinegar to use as the rocket fuel. Students then identify and test variables that may affect the reaction and the rocket trajectory. For the final competition, the rocket that clears the meter mark with the greatest rocket-to-baking soda mass ratio is the winner!
Complete for 30 students working in pairs.
Stoichiometry... Can You Make 2.00 Grams of a Compound? Super Value Guided-Inquiry Kit By: Mark A. Case
Emmaus High School, Emmaus, PA
Students become industrial chemists! Their goal—to apply stoichio- metric relationships from a balanced equation to make 2.00 grams of a product. Using two compounds, students calculate the amount of each chemical they need and, through a double displacement reac- tion, produce exactly 2.00 grams of a precipitate. The dried precipitate will be turned in for verification and grading. The percentage of error for the experiment will also be calculated. Instructor’s Notes provide ample background information, detailed procedures and sample data. A reproducible student worksheet is also provided. Ample amounts of six different chemicals are provided.
Super Value Kit is complete for 5 classes of 24 students working in pairs.
Target Stoichiometry—
Student Laboratory Kit
By: Bob Becker
Kirkwood H.S., Kirkwood, MO
Using stoichiometry and a balanced chemical reaction, students predict the mass of product for their reaction! How close the prediction is to the final mass weighed determines their final score. Students will stay engaged and on target in this fun and challenging activity. To achieve the top grade, students will need to utilize their best lab etiquette! Have fun motivating your students to stay on target using the law of conser- vation of mass!
Complete for 30 students working in pairs.
