Chemistry of Lightsticks: Determination of Activation Energy, a Guided Inquiry Approach

Lightsticks, with their eerie glow, capture the interest of students of every age. Capitalizing on this, the authors describe how they developed and used a guided inquiry approach to help students determine the activation energy of the chemiluminescent reaction in a lightstick. They also describe how they used a Vernier LabQuest 2 system, while acknowledging that any data collection system that allows simultaneous collection of data from light and temperature probes may be used instead. In addtion, they explain how they employed the natural logarithm form of the Arrhenius equation and spreadsheet software.

States of Matter and Phase Changes Listimage simulation cropped sept18

In this simulation, students will participate in a 10 question quiz. Some questions will challenge students to analyze data to identify the correct state of matter for a specific sample, and then connect the chosen state with an animated particle diagram. In addition, students will examine the behavior of particles in an animated sample as they undergo a phase change, and must correctly identify the change that occurs.
