360Storylines—Fast & Slow Processes, 1-Year Access

Product Details

A 360Storyline is a collection of experiments that together let students engage in science in an authentic manner through the use of relevant phenomena. Each experiment in a 360Storyline builds on things learned in the preceding experiments until students develop a final, working explanation or model of the phenomenon. Every lab in any 360Storyline is completely editable and supported by videos and simulations. 

Includes:

• Access to digital content for 1 year
• Lab supplies for each experiment for a single class of 30 students

Fast & Slow Processes
Lead students to a written understanding/working model of chemical equilibria and reaction rates. Students will understand how different chemical reactions may achieve equilibrium and that reactions’ rates may follow different rate laws, and they will figure out how these rates can be measured. Following completion of this storyline, students will be able to examine the natural world and explain the usefulness of things like refrigeration and pressure and temperature control in manufacturing processes such as the Haber process, for nitrogen fixation.

What Students Do

Lab 1—Introduction to Chemical Reactions
Students observe and classify different reactions. In addition to classifying, students balance the chemical equations.

Lab 2—Kinetics of Crystal Violet Fading
Students apply spectroscopy and graphical analysis to determine the rate law for the color-fading reaction of crystal violet with sodium hydroxide.

Lab 3—Rate of Decomposition of Metal Carbonates
Students explore the kinetics of thermal decomposition of various metal carbonates at high temperatures.

Lab 4—Application of Le Chatelier’s Principle
Students investigate different chemical reactions to gain a deeper understanding of equilibrium and Le Chatelier’s principle. They apply deliberate stresses on these systems to cause their equilibria to shift.

Lab 5—Reaction Rates: Iodine Clock
Students carry out an investigation to determine how the rate of the iodine clock reaction is affected by the concentration of the reactants involved.

Lab 6—Explore Chemical Equilibrium
Students carry out an investigation to observe changes in equilibria when the amount of reactants, products and/or temperature are changed. Students observe how various reactions can shift to the product or reactant side and how it relates to Le Chatelier’s principle.

About 360Storylines

A 360Storyline is a collection of experiments that together let students engage in science in an authentic manner through the use of relevant phenomena. Each experiment in a 360Storyline builds on things learned in the preceding experiments until students develop a final, working explanation or model of the phenomenon. Every lab in any 360Storyline is completely editable and supported by videos and simulations. 

Students must drive the learning forward by developing procedures and asking questions. Each storyline is supported by editable documents that force students to think about how the data they collect relate to an individual experiment’s investigative phenomenon and how the data they collect in a series of labs relate to a broader, anchoring phenomenon.
