đ§ Episode 27: The Root Beer Lab â From Sublimation to Ocean Acidification If your students love lab daysâŠbut struggle to connect them to actual chemistry concepts, this episode is for you. Today Iâm walking you through one of my all-time favorite labs...making root beer with dry ice đș (donât worryâŠno fermentation happening here đ). It might feel a little âfluffyâ at first, but I promiseâthere is some really solid chemistry packed into this activity. Weâre talking phase changes, intermolecular forces, acids and bases, and even ocean acidificationâall in one engaging lab your students will remember. đ§Ș In This Episode, Youâll Learn: đ§ Sublimation in Action How I use dry ice and âspooky fogâ to help students see phase changes instead of just memorizing them đ Making Phase Diagrams A simple way to compare water vs. carbon dioxide, so students understand why COâ skips the liquid phase at normal pressure đ§ Intermolecular Forces (Without the Eye Glaze đ ) How I connect weak London dispersion forces to what students are actually observing in the lab đ„€ Why Soda Is Acidic (and Why That Matters) Using carbonic acid to connect COâ + HâO to real-world examples like flat sodaâand ocean acidification đ Real-World Connections That Stick How this lab leads naturally into a conversation about carbon sinks, ocean chemistry, and impacts on marine life đ ïž Lab Tips & Teacher Moves From my âwitchâs brewâ stirring moment đ§ââïž to managing dry ice safely and efficiently in class đ Resources & Links đ§Ș Free Root Beer Lab Slides [https://docs.google.com/presentation/d/1RTFZaGKHKZ9eONw74l26xvQBcWzGAZOu6WZjk0-LkGs/copy] & Worksheet [https://docs.google.com/document/d/1nFUEPSKgasROPbWf16H2dfjKrlNbpVyrmeYOFKcedMY/copy] Iâm sharing the exact materials I use in my classroomâgrab them in the show notes and try it out yourself! đ Itâs All About Carbon Activity (TPT) [https://www.teacherspayteachers.com/Product/Its-All-About-Carbon-An-Introduction-to-Environmental-Chemistry-Earth-Day-6738056] If you want to go deeper with carbon cycles and real-world connections, this is a great extension for your students đ§Ș Join the Lab Membership Waitlist [https://learn.chemschemistryclassroom.com/lab-membership-waitlist] This lab is a perfect example of the kind of ready-to-run, classroom-tested resources coming to the Confident Chemistry Teacher Lab Membership this October đ Join the waitlist to get first access (and founding member pricing!) đĄ Teacher Tip of the Week: Dry ice doesnât melt⊠it disappears đ If you buy 5 pounds the night before, you might walk into school with only 2 pounds left by first period. Save yourself the stress and call aheadâhave your store hold it for you the morning of your lab. đïž Coming Next Week⊠Next episode, Iâm switching gears a bit and sharing how Iâm planning my summer goalsâboth for my classroom and my business. If youâve ever felt like summer flies by and you didnât get done what you wanted to get doneâŠthis oneâs for you. đ As always⊠Keep inspiring, keep experimenting, and keep being awesome in your classrooms. đ Website: chemschemistryclassroom.com đ©âđ« Join our community: The Confident Chemistry Teacher Facebook Group https://www.facebook.com/groups/767528946010479/ đž Come say hi on Instagram: @chemschemistryclassroom đ Grab resources on TPT: Chemâs Chemistry Classroom [https://www.teacherspayteachers.com/store/chems-chemistry-classroom]
