In a good general chemistry class, strong problem solving asks students to do more than identify an equation and plug in numbers. They need to understand the situation, recognize the chemistry involved, plan a path forward, and evaluate whether their answer makes sense. A simple, repeatable process can help students build those habits: Read &…

Fall is a great time to turn everyday observations into chemistry questions 🍎🥧 Take a cut apple. Leave it on the counter for a few minutes, and the surface starts to turn brown. Why? Cutting the apple exposes compounds inside its cells to oxygen. Enzymes help drive reactions that produce brown-colored compounds, a process called…

Back-to-school season is the perfect time to think about the small things that can make a general chemistry course run a little more smoothly. Maybe that’s a new way to introduce a difficult concept. A different kind of practice before an exam. A quick look at where students are getting stuck. Or a resource that…

From comic book heroes to sci-fi movies, radiation gets a pretty dramatic reputation. But what actually makes an atomic nucleus radioactive? What makes one isotope stable while another decays? In this video, Ariel Anbar, professor and isotope geochemist at Arizona State University, takes us inside the atomic nucleus to explore the delicate balance between protons…

Have you heard of the ozone hole? Mario Molina discovered the chemistry that caused it, and he is one of five chemists we are celebrating as we honor Hispanic Heritage Month at REAL CHEM. The discoveries below range from the ozone layer to the insulin in a pharmacy today: • Mario Molina traced stratospheric ozone…

Which is your favorite, hot tea or iced tea? 🍵🧊 Temperature and pH help explain why the same tea can feel so different. In this lesson, Clarice Phelps, nuclear chemist at Oak Ridge National Laboratory, explores the chemistry behind temperature, pH, acids, bases, and proton transfer, and how these concepts connect to the world around…

Week two of the semester, and everyone is under stress. So, you NEED to reach a state of balance. Chemistry has a term for that, and it's called equilibrium! In this tutorial video, cobalt(II) nitrate dissolves in water to form a pink aqua cobalt complex. Adding hydrochloric acid introduces chloride ions. Then, those ions interact…

REAL CHEM’s Exploration gave Tori a new perspective on climate change in the Pacific Islands she calls home and deepened her appreciation for chemistry by helping her investigate the changes she sees in her own community. Biodiversity Month reminds us that connecting chemistry to what matters to students can motivate them to tackle challenging concepts…

Here’s a question worth ten minutes of your first week back-to-school: Where do students see chemistry in their lives, their communities, or future careers? Start with career, because chemistry sits at the front of more paths than students might realize: ✅ Nursing and health professions, where dosage math and pH come up daily ✅ Cosmetic…

The fall equinox is more than the unofficial beginning of sweater weather. It’s also a pretty great astronomy lesson! 🔭 On September 22, the Northern Hemisphere reaches the September equinox, when the Sun crosses the celestial equator moving southward. But the science behind the season is even more interesting. For college instructors, the equinox is…
