š§ Episode 27: The Root Beer Lab ā From Sublimation to Ocean Acidification If your students love lab daysā¦but struggle to connect them to actual chemistry concepts, this episode is for you. Today Iām walking you through one of my all-time favorite labs...making root beer with dry ice šŗ (donāt worryā¦no fermentation happening here š). It might feel a little āfluffyā at first, but I promiseāthere is some really solid chemistry packed into this activity. Weāre talking phase changes, intermolecular forces, acids and bases, and even ocean acidificationāall in one engaging lab your students will remember. š§Ŗ In This Episode, Youāll Learn: š§ Sublimation in Action How I use dry ice and āspooky fogā to help students see phase changes instead of just memorizing them š Making Phase Diagrams A simple way to compare water vs. carbon dioxide, so students understand why COā skips the liquid phase at normal pressure š§ Intermolecular Forces (Without the Eye Glaze š ) How I connect weak London dispersion forces to what students are actually observing in the lab š„¤ Why Soda Is Acidic (and Why That Matters) Using carbonic acid to connect COā + HāO to real-world examples like flat sodaāand ocean acidification š Real-World Connections That Stick How this lab leads naturally into a conversation about carbon sinks, ocean chemistry, and impacts on marine life š ļø Lab Tips & Teacher Moves From my āwitchās brewā stirring moment š§āāļø to managing dry ice safely and efficiently in class š Resources & Links š§Ŗ Free Root Beer Lab Slides [https://docs.google.com/presentation/d/1RTFZaGKHKZ9eONw74l26xvQBcWzGAZOu6WZjk0-LkGs/copy] & Worksheet [https://docs.google.com/document/d/1nFUEPSKgasROPbWf16H2dfjKrlNbpVyrmeYOFKcedMY/copy] Iām sharing the exact materials I use in my classroomāgrab them in the show notes and try it out yourself! š Itās 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 š§Ŗ 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 š Join the waitlist to get first access (and founding member pricing!) š” Teacher Tip of the Week: Dry ice doesnāt melt⦠it disappears š 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 aheadāhave your store hold it for you the morning of your lab. šļø Coming Next Week⦠Next episode, Iām switching gears a bit and sharing how Iām planning my summer goalsāboth for my classroom and my business. If youāve ever felt like summer flies by and you didnāt get done what you wanted to get doneā¦this oneās for you. š As always⦠Keep inspiring, keep experimenting, and keep being awesome in your classrooms. š Website: chemschemistryclassroom.com š©āš« Join our community: The Confident Chemistry Teacher Facebook Group https://www.facebook.com/groups/767528946010479/Ā šø Come say hi on Instagram: @chemschemistryclassroom š Grab resources on TPT:Ā Chemās Chemistry Classroom [https://www.teacherspayteachers.com/store/chems-chemistry-classroom]
