The January 2025 Xchange highlights just some of the contributions that have recently been published on ChemEd X. We hope you will take a moment to check in and see what you may have missed. 

Passing the Torch: A Fond Farewell Exciting changes at ChemEd X! A heartfelt farewell from outgoing editor, Deanna Cullen, and a warm welcome to Erica Posthuma, our new High School Editor.
	APTeach - Entering Equilibrium Join AP Teach in discussing chemical equilibrium to address common student misconceptions as well as ideas for engaging activities and labs to strengthen student comprehension.
The Diamonds of Winter Take a walk and explore the chemical winter wonderland of snowflakes...and diamonds!
	Models of Chlorinated Hydrocarbons and Dipoles Explore chlorinated hydrocarbons and dipoles with paper and toy models like LEGO, K’Nex, and Lux Blox! Paper models reinforce molecule polarity lessons, with templates and assignments included in the Supporting Information.
How a Burning Candle Can Teach Stoichiometry Make stoichiometry relatable! In this simple lab, students measure the mass of a burning candle and explore key questions like: 'How much CO₂ does a candle produce?' and 'How can we quantify CO₂ from engines?' Minimal setup, real-world impact, and engaging results!
	Application of the Ideal Gas Law and Avogadro’s Hypothesis Engage your Chemistry students with a dynamic, 40-minute lab that uses the Ideal Gas Law to uncover the molar masses of "mystery gases." Perfect for Grade 11 or Honors Chemistry, this adaptable experiment combines theory with real-world applications!
