  • Kool aid smaller v2
    Resource Feature | November 2017 A Particulate Representation of Molarity

    In addition to using a simple activity about investigating the differences Kool-Aid concentration and completing molarity calculations, students work with pictures at the particle level to develop a deeper understanding of solutions and molarity.

  • Cs november 2017 simulation
    Simulation | November 2017 Predicting Shifts in Equilibrium: Q vs K

    In this simulation, students will take a 15 question quiz. Each quiz question has two parts. The first part requires the student to calculate the value of the reaction quotient, Q. In the second portion of the question, the students will compare the value of Q to the equilibrium constant, K, and predict which way the reaction will shift to reach equilibrium. The simulation includes five different reactions which each have three scenarios: Q > K, Q = K, and Q < K.

  • Simulation measuring volume 1
    Simulation | September 2017 Measuring Volume

    In this simulation, students will participate in a 10 question quiz. The quiz questions are each made of two parts, with the first part requiring the student to analyze an image of a graduated cylinder in order to report an accurate measurement. Students must use the correct number of digits based on the markings presented on the cylinder when reporting the measurement. In the second portion of the question the students will determine the uncertainty value of the graduated cylinder, again by analyzing its markings. The simulation is made up of several different sizes of graduated cylinders, each containing unique markings, so students will be challenged to analyze each individually.

    Classroom Commentary | September 2017 One Teacher’s Journey on the Path to Modeling Instruction

    This article describes a teacher’s journey and reflections over her 27-year career as she moved from a traditional chemistry classroom to one using modeling instruction techniques. To illustrate a central insight she gained along her journey, she describes one activity in particular, Sticky Tape. In this activity, students find evidence for charged particles smaller than an atom, and the discussion after the activity ultimately leads them to the subatomic particle we know as the electron. Making the move to incorporating modeling instruction transformed the author’s classroom and teaching style, and her students are now much more engaged in their own learning.

  • Vsepr 220
    Resource Feature | September 2017 ​Increasing Student Comprehension of VSEPR Theory​

    In the activity described in this article, students construct physical models of molecular shapes. However, students are not told what the preferred arrangements of electron pair domains are. Instead, they derive the arrangements. Students are given the opportunity to conceptualize what is happening when one electron pair domain acts upon another, and to understand how those interactions result in the molecular geometries predicted by VSEPR theory. As an outcome of examining the physical basis of the VSEPR model, students should have a much better grasp of the implications of electron pair repulsions on molecular shape, and should be better able to understand, communicate, and apply that understanding.
