Chemistry Timeline

Timeline Interactive

In this interactive, you will learn more about key chemistry-related people and events from prehistoric times to the present. The timeline targets major breakthroughs in the development of chemical science, including the discovery of key elements, as well as the birth and death dates of important contributors chemistry history. As you scroll forward and backward in time, or use a navigation bar to quickly jump to different points of chemical history, you will see the connection between chemical discoveries and other key events in human history. Clicking on a person or date will bring up more information about the selection and provide links to relevant material in the Units. Targeted for all Units 1-13.

Control a Haber-Bosch Ammonia Plant

Haber Interactive

You will learn about the economics of operating a chemical factory as you try to optimize the process of a simulated Haber-Bosch process ammonia fertilizer plant. Key concepts include: equilibrium reactions, catalysts, reaction energies, thermo-chemistry, and kinetics. You are challenged to maximize profitability by fine-tuning the reaction: adjusting temperature and pressure in the reaction chamber, switching the type of catalyst, and adjusting the rate that the product (ammonia) and impurities are removed. Every input has a cost associated with it, so you will have to apply what you know about chemical reactions to be successful. This lab is most closely linked to concepts in Units 6, 7 9, and 12.

The Chemistry of Running

Running Interactive

You will learn about the chemistry of exercise through this running simulation lab. Key concepts include: the difference between aerobic and anaerobic exercise, aerobic fitness level (represented by a measure called VO2max), and blood pH. When the lab starts, you will run a marathon, controlling the speed of your runner and seeing how changing levels of effort changes the acid-base balance in the body. You will be challenged to improve your time by reviewing your chemical parameters after each race, and doing additional training to improve maximum aerobic levels. This lab is a practical application of the content in Units 6-11, including solutions, acid-base reactions, thermodynamics, and energy. Lesson Plan | Student Worksheet
