  1. Evaluation/Application Projects • To apply what you have learned about chemical reactions to the following topics: • The Hindenburg Explosion: Explain how the reaction between hydrogen and oxygen affected the disaster. • Statue of Liberty Corrosion: Explain how the reaction between copper and oxygen affected this occurrence. Also explain how the reaction between copper and acid rain affected the rate of reaction. • Hydrogen Cars: How do chemical reactions cause hydrogen cars to run? • Air Bags: How are air bags being changed and/or redesigned to improve their safety and effectiveness. • Battery Technology: What is the new battery technology? What is involved in the chemical reaction inside the battery? • Electrolysis of Water: What is the chemical reaction that occurs during electrolysis? How is the electrolysis of water used? • Popcorn: What causes a popcorn kernel to pop? What variables affect the popping quality of kernels? What type of change is the popping? • Hot/Cold Packs: What is the chemical reaction that produces the heat or cold? What is a reaction called that gives off/takes in heat energy? • Caves (Limestone Landscape): What chemical reaction forms caves and how does it happen in nature? What speeds up or slows down this chemical reaction? • Fireworks: What are all the chemical reactions involved in fireworks? What is the history and uses of fireworks? What causes the different colors/sounds of fireworks?

  2. Evaluation Activity: Chemical Reactions Research Project • Objective: To apply your knowledge of chemical reactions by researching one chemical reaction occurrence and teaching the class about your chemical reaction occurrence. • Procedure: • Use the website resources provided to on the next slide to help you learn about your chosen reaction. Answer the project questions. • Create a 5-slide power point slide show presentation to be used as an instructional tool for teaching us about your reaction. (presentation is a past/fail grade) • Take notes on each presentation as it is presented. Answer the BCR question on each topic at the presentation of each. • Self assess all your BCRs and choose two to turn in for grading.
