Episode 34: 3 Hands-On Matter and Change Activities for High School Chemistry Matter and Change can sometimes feel like one of those basic vocabulary units in high school chemistry—but I actually think it’s a great opportunity to get students into the lab and start building skills they’ll use all year long. In this episode of The Confident Chemistry Teacher Podcast, I’m sharing three of my favorite hands-on Matter and Change activities: my Goodie Brittle Lab, paper chromatography, and Matter and Change Stations. Yes, students are learning about physical and chemical changes, mixtures, and separation techniques. But they’re also learning how to use lab equipment, follow procedures, make good observations, take measurements, and use evidence to support their conclusions. And those are skills we’re going to come back to again and again throughout the year. 📚 In This Episode, You’ll Learn: Why I teach Scientific Measurement before my Matter and Change unit How I use my Goodie Brittle Lab to let students actually experience physical and chemical changes A few different ways to use paper chromatography to teach separation techniques How chromatography can connect to Biology, AP Chemistry, and even a little forensic science How I set up my Matter and Change Stations as a hands-on review before the test Some of my favorite chemistry lab stations, including magnetic separation, evaporation, conductivity, burning magnesium, filtration, and precipitation reactions How I use these early chemistry labs to build students’ confidence with lab equipment and procedures 💬 Teacher Tip of the Week When you’re planning an early chemistry unit like Matter and Change, think beyond just the content you need to cover. Ask yourself: What can my students practice now that will make things easier later in the year? That’s really why I love these activities. Instead of just memorizing that melting is a physical change or that chromatography is a separation technique, my students actually get to experience these things. They’re also getting comfortable with hot plates, Bunsen burners, conductivity meters, filtration, measuring, making observations, following procedures, and cleaning up their lab stations. Then, when we use those skills again later in the year, they’ve already done them before. 🧪 Activities, Labs & Strategies Mentioned Goodie Brittle Lab This is basically a peanut brittle lab—but I call it Goodie Brittle because students can add things like Oreos, graham crackers, gummy bears, or other goodies instead of peanuts. As the students melt the sugar and make their brittle, they can observe physical and chemical changes happening right in front of them. I also like this lab because it gives students some early practice using a hot plate, handling hot materials, following procedures, working with a group, making detailed observations, and cleaning up a lab station. And let's be honest—chemistry is always a little more fun when you get to eat something at the end. Paper Chromatography Paper chromatography is one of my favorite simple ways to introduce separation techniques in chemistry. You can keep this activity really simple and use different black markers, or you can make it more involved by comparing plant pigments or turning it into a mystery students need to solve. Students get practice setting up their chromatography correctly, making observations, measuring distances, comparing results, and drawing conclusions from their evidence. If you want to take it a little further, you can even introduce Rf values. Matter and Change Stations My Matter and Change Stations are usually a culminating activity that I use as a hands-on review before the unit test. Depending on how much time I have, I might set up anywhere from four to eight different stations and have students rotate through the mini experiments. Some of my favorites include: Separating iron filings from sand with a magnet Evaporating water from a saltwater mixture Testing conductivity Burning magnesium Separating sand and water using filtration Observing a precipitation reaction Some of these experiments are really simple, but that’s okay! Especially at the beginning of the year, students are still gaining confidence in the chemistry lab. I want them using equipment, following procedures, making observations, and practicing the vocabulary we’ve been learning.   💻 Let’s Connect Looking for more high school chemistry labs, activities, teaching strategies, and classroom resources?

Episode 33: 3 Activities to Strengthen Scientific Number Sense in Chemistry Can your students do the math…but struggle to understand what the numbers actually mean? I remember sitting in my own honors chemistry class, successfully calculating Ka and Kb values without really understanding why I was doing those calculations. That experience has shaped the way I teach chemistry today. I want my students to understand the concepts first and then use the math to support that understanding. And lately, I’ve noticed that students are coming into chemistry struggling with some pretty basic number sense — exponents, scale, units, precision, and even understanding what makes one number bigger or smaller than another. In this episode, I’m sharing three simple activities I use to strengthen scientific number sense and give students a better foundation for the calculations they'll encounter throughout chemistry. 🧪 In This Episode, You’ll Learn Why scientific number sense deserves some intentional attention at the beginning of chemistry How a physical number line can help students visualize scale, magnitude, units, and exponents A simple paperclip activity that helps students understand estimated digits and why significant figures matter How different measuring devices can help students see the relationship between measurement and precision How a density of metals lab moves students beyond simply calculating an answer to actually interpreting and evaluating their results Why building these skills early can make later chemistry calculations more meaningful 📏 Activity #1: Build a Physical Number Line Atoms, wavelengths, particles, and moles require students to work with numbers that are either incredibly small or incredibly large. Instead of jumping immediately into scientific notation, I like to give students something more concrete. Students arrange familiar objects — from something as large as the sun to something as small as an atom or proton — along a physical number line. From there, we add units, measurements, and powers of ten. The goal is to help students move from visual → numerical → conceptual and really think about what it means for something to be 10, 100, or even thousands of times larger or smaller. 📎 Activity #2: Paperclips, Rulers & Estimated Digits Why do we need significant figures anyway? For this activity, students measure the same paperclip using three rulers with different levels of precision. As the measuring devices become more precise, students begin to see why we record an estimated digit and why 5.0 communicates something different from simply writing 5. It's an easy activity, but it opens the door to some important conversations about: Accuracy and precision Estimated digits The precision of measuring instruments Significant figures Why we don't report eight or ten decimal places just because our calculator gives them to us Best of all, you can do it with something as simple as a paperclip! 🔬 Activity #3: Density of Metals For the third activity, students put those measurement skills into practice with a density of metals investigation. Students use mass and water displacement to calculate the density of an unknown metal — but I don't want them to stop when they get an answer. Instead, we start asking questions: Does your calculated density make sense? What metal do you think you have? What evidence supports your conclusion? How might the precision of your measurements affect your result? The goal is to help students understand that chemistry isn't just about getting a number. It's about being able to interpret, evaluate, and use that number as evidence. 🛒 Resource Mentioned in This Episode If you're teaching scientific measurement, I have a Scientific Measurement Google Slides presentation available in my TPT store. The resource includes instruction and practice with significant-figure rules, identifying and counting significant figures, significant-figure calculations, fill-in-the-blank student notes, and videos students can use if they're absent or need additional support.

Episode 32: What Chemicals Do You Really Need in Your Chemistry Classroom? If you’re a new chemistry teacher staring at your chemical storage room wondering, “What do I actually need?” — this episode is for you. Over 19 years of teaching chemistry, I’ve learned that you don’t need every chemical in the catalog to create meaningful, hands-on experiences for your students. What you need are versatile chemicals that can be used across multiple units and labs. In this episode, I’m walking you through the chemicals I find most useful for teaching everything from acids and bases to chemical reactions, stoichiometry, solutions, and atomic structure. I’ll also share some inexpensive grocery-store alternatives you can use when your lab budget is tight — plus the five chemicals I would prioritize if I had to start from scratch.   🧪 In This Episode, You’ll Learn Which chemicals can be used across multiple chemistry units My go-to chemicals for acids, bases, reactions, precipitation, solutions, stoichiometry, and flame tests Why I love magnesium ribbon so much that it gets a chef’s kiss 💋 How everyday materials like vinegar, baking soda, Alka-Seltzer, sugar, salt, oil, and dish soap can support meaningful chemistry investigations Why buying every chemical you might use isn't necessarily the best way to spend your lab budget How to gradually build a chemistry stockroom around the labs you actually teach   🔬 Labs & Activities Mentioned Throughout the episode, I share ways these chemicals can be used for: Acid-base indicators and pH testing Neutralization and titration Physical and chemical changes Single and doublereplacement reactions Precipitation and solubility investigations Gas production and catalyst demonstrations Flame tests and atomic emission spectra Solution preparation and serial dilution Limiting reactants and stoichiometry Conservation of mass Density and polarity Reaction-rate inquiry labs And remember — you don’t necessarily need specialized laboratory chemicals for every one of these experiences. Some great chemistry can happen with materials from the grocery store!   ⭐ If I Could Only Buy Five Chemicals... If I were building a chemistry stockroom and had to prioritize just five, I would choose: Hydrochloric acid Sodium hydroxide Copper(II) sulfate Magnesium ribbon Calcium chloride These give you lots of flexibility across different units and can support a surprising number of labs and demonstrations throughout the year. Of course, always follow your school or district's chemical purchasing, storage, handling, and disposal requirements and the appropriate SDS information.   🛒 Chemistry on a Budget Don't have a fully stocked chemical storage room yet? That's okay. Vinegar, baking soda, Alka-Seltzer, hydrogen peroxide, sugar, salt, corn syrup, vegetable oil, and dish soap can give students hands-on experiences with acids and bases, reaction rates, gas production, density, solutions, polarity, conductivity, and physical and chemical changes. Start with the labs you know you'll teach, and build your chemical inventory over time. You don't have to create your dream chemistry lab during your first year.   🚀 Want More Chemistry Teaching Support?

Episode Intro In this episode of The Confident Chemistry Teacher Podcast, I’m taking you inside my mole unit — not as a day-by-day plan, but through the thinking and teaching decisions behind it. The mole unit is one of the first truly skill-heavy units students encounter in chemistry, and it can feel overwhelming for both students and teachers. I share how I introduce the mole conceptually, how I scaffold practice, how I check for mastery along the way, and how I help students build confidence before the test. My goal is always the same: helping students actually learn chemistry, not just survive the unit.   Key Takeaways By the end of this episode, you’ll hear how to: Frame the mole as a skill-based unit, not a memorization unit Help students visualize the scale of the mole before jumping into math Scaffold mole conversions so students don’t shut down Balance independent practice with more active, collaborative practice Use mastery checks to guide instruction before the unit test Reinforce the importance of showing work and using units   How I Introduce the Mole Unit I begin the unit by helping students understand scale. Before touching conversions, I want them to grasp how large Avogadro’s number really is. I use a short video, How Big Is the Mole?, to help students visualize scale. We discuss why chemists need a way to count particles they can’t see. I connect atomic mass units to grams to show why mass is the bridge between the microscopic and real-world chemistry. To make this concrete, I use a “measuring by mass” activity with paperclips, which helps students understand how counting by mass works in a tangible way.   Teaching & Practicing Core Mole Skills Even though this is a math-heavy unit, I rely on explicit modeling through Google Slides. My slides focus on how to think through problems, not just the answers. I typically teach skills in this order: Molar mass Mole-to-gram and gram-to-mole conversions Moles to representative particles and liters Multi-step (double conversion) problems Percent composition, empirical formulas, and molecular formulas Throughout the unit, I remind students that dimensional analysis is a tool, not a trick — something they already know how to use.   Practice: Boring Practice + Fun-ish Practice Because chemistry skills require repetition, I intentionally plan for both types of practice. Independent practice: Worksheets for building confidence Quiet work time so students can’t rely on neighbors Active or “fun-ish” practice: Rock–Paper–Scissors review Whiteboarding Small-group and partner practice Practice tests in mixed-ability groups This balance supports both skill mastery and student engagement.   Mastery Checks (Before the Test) Instead of waiting until the unit test to find gaps, I use short mastery checks throughout the unit. Each mastery check is only a few questions. Students receive feedback quickly. Retakes are built in when students show effort These checkpoints: Create urgency Prevent last-minute cramming Help me adjust instruction with warm-ups, extra practice, or short videos   Labs & Hands-On Learning Labs in the mole unit help students connect math to real substances. Some of my favorites include: Counting by measuring mass (early in the unit) Avogadro and the Mole lab using real substances Extension activities like Mole Olympics or sewing a mole These activities don’t replace instruction — they enhance understanding and make the unit more memorable.   Assessment & Grading Philosophy My assessments are a mix of multiple choice and free response, with a strong emphasis on showing work. I use a consistent grading approach: Credit for showing work Partial credit for reasonable answers Points for units and significant figures Using the same expectations from the start helps students understand what matters and builds confidence over time.   Final Takeaway The goal of the mole unit isn’t just passing a test — it’s helping students believe they can do hard, skill-based chemistry. When students leave this unit knowing they can: Set up conversions Use units correctly Explain their thinking …it sets them up for success in stoichiometry and beyond.   Closing As always, thank you for listening to today’s episode.

Episode Intro In this episode of The Confident Chemistry Teacher Podcast, I’m sharing the key systems and teaching practices I’m focusing on in 2026 to help me feel more organized, reduce decision fatigue, and actually enjoy the spring semester with my students. Like many teachers, I’ve felt overwhelmed this year — new responsibilities, new classes, and the constant pressure to keep up with curriculum pacing. Instead of trying to do everything, I’m intentionally focusing on a few core systems that support both student learning and teacher sustainability. If you’re feeling stretched thin right now, this episode is meant to remind you that you’re not alone — and that small, intentional shifts can make a big difference. Key Takeaways By the end of this episode, you’ll hear about: How creating structured weekly routines can reduce decision fatigue and improve student behavior Why I’m committing to a monthly checklist system to stay organized and prepared How modeling expectations more intentionally leads to smoother lessons and labs Why being intentionally positive with students matters — especially during challenging semesters Teaching Systems & Practices Featured 🧪 1. Structured Weeks I’m moving toward a more predictable weekly structure: Monday: Notes and light practice Tuesday & Wednesday: Activities or labs Thursday: Review, notebook organization, and practice test work Friday: Quiz or test This structure helps me prioritize essential content, reduces planning stress, and gives students clear expectations. 📋 2. Using a Monthly Checklist To manage everything on my plate, I’m leaning into a monthly checklist broken into four sections. Instead of trying to do everything at once, I focus on one section per week and use staff development days strategically. I’ve also committed to staying one extra afternoon a week (Thursdays) for focused planning, grading, and lab prep — so work doesn’t spill into every evening or weekend. 🎯 3. Modeling More for Students This semester, I’m being more intentional about: Modeling procedures Modeling lab techniques Modeling notebook setup If students don’t do something correctly, I’m having them go back and repeat it. I’ve learned that when I’m frustrated later, it’s usually because I skipped modeling earlier. 🌱 4. Being Intentionally Positive I’m working on using more positive language and recognition in my classroom, including: Verbal praise for effort and growth Calling out groups who are working well Stickers on assessments Small academic rewards The goal is to help students build confidence so that external motivation can eventually turn into internal motivation. What’s Coming Next on the Podcast As the year continues, I’ll be sharing: How I plan chemistry units using these systems Deeper explanations of why I structure lessons the way I do Episodes on labs like my dry ice root beer lab, gas laws activities, and other high-engagement chemistry experiences My goal is to help you adapt strategies — even if you don’t teach the exact same labs or units. Final Encouragement If you’re feeling overwhelmed, remember: You don’t need to do a thousand new things You don’t need a complete overhaul. One intentional system can make a big difference Closing As always, thank you for listening to today’s episode. Teaching chemistry can feel overwhelming, but I hope this episode gave you one idea, one strategy, or one small shift you can take back to your classroom. If you found this episode helpful, please share it with another chemistry teacher who might need some encouragement. And until next time — keep inspiring, keep experimenting, and keep being awesome in your chemistry classroom. Happy teaching.
