When we reach our Weather and Climate unit, the student notebooks fill with charts, graphs, and maps. They work to point out trends and ask questions. This is where the Science and Engineering Practice of Analyzing and Interpreting Data comes alive.
Start with Pre-Reading Before students dive into a graph, we pause to pre-read it together. This step helps them slow down and make sense of what they are looking at. We look carefully at the title, the x-axis, the y-axis, and any labels or keys. We talk about what each part represents and what kind of data is being shown. This simple routine helps students avoid jumping straight to conclusions. They learn to ask, "What is the graph trying to tell me?" before asking, "What does it mean?" That shift in order makes a big difference. Seeing Beyond the Numbers At first, students look at a weather graph the same way they would read a sentence, from left to right, searching for something to label "right." But with guidance, they start to notice relationships and patterns. They ask things like, "Why are some sections increasing and some sections remain constant?" or "What does that sudden drop in air pressure mean?" That is the shift I am looking for. They move from describing to wondering, and from wondering to explaining. Data Has a Story Each graph we study tells a story. The challenge is helping students find it. Sometimes we compare climate data from Jeju and Cairo. Other times, we study how temperature and air pressure interact over several days. I ask students to look for patterns, to think about cause and effect, and to use evidence to support their ideas. To help make this work accessible to all students, we use sentence starters such as: "When increases, tends to..." "The data suggests that..." "This might mean that..." These small supports help students focus less on decoding the graph and more on thinking about what the data actually means. Talking Through the Patterns Before they write, students discuss what they see. These conversations are where real understanding grows. When a student says, "I think the warm front caused that rise in humidity," and another replies, "But the wind direction changed first," I know they are thinking critically. They are testing ideas, revising them, and learning that scientific understanding is built through dialogue. From Patterns to Predictions By the end of the unit, students use real-world data to make their own short-term weather forecasts. They combine their understanding of air masses, fronts, and local data to predict what might happen next. Their final CER writing is not just about stating a claim; it is about showing how their interpretation of the data supports it. Why This Practice Matters Helping students analyze and interpret data is more than a science goal. It is a life skill. They learn that data is not something distant or abstract. It is evidence, something they can use to explain, predict, and understand the world around them. When students start to see patterns in the clouds and connections in the data, science becomes more than facts on a page. It becomes a way of thinking, and that is where the real learning happens.

One of the core Science and Engineering Practices in the NGSS framework is Engaging in Argument from Evidence. In my classroom, this practice is not about debating to win. It is about helping students learn how to support their ideas with evidence, listen respectfully to others, and refine their thinking through dialogue. Beginning with Inquiry: Who is Ms. Hart?
From Evidence to Dialogue: Science Circle
From Dialogue to Writing: CER Following the Science Circle, students synthesize their learning in writing through Claim, Evidence, Reasoning (CER). This framework gives them a clear structure for building arguments:
Why This Practice Matter Engaging in argument from evidence is more than a science skill. It builds critical thinkers who can support their ideas clearly, consider multiple viewpoints, and change their minds when stronger evidence is presented. These are habits that prepare students for advanced study, professional life, and responsible citizenship.
By designing a sequence that begins with inquiry (Who is Ms. Hart?), moves into dialogue (Science Circles), and culminates in synthesis (CER writing), I help students see how argument from evidence connects across all aspects of learning. This practice makes science both rigorous and meaningful. Students learn that evidence is the common ground where understanding grows, and that their voices matter when they bring evidence into the conversation. In our Grade 6 science program, Obtaining, Evaluating, and Communicating Information is not just a standard on paper. It is a habit we intentionally build, starting with projects like Who is Ms. Hart?
During this project, students obtain information by collecting data from videos, classroom observations, student feedback, and clues hidden around the room. They evaluate information as they sort which evidence is relevant, reliable, and strong enough to support a claim about my MBTI type. Finally, they communicate information by writing a Claim, Evidence, Reasoning (CER) paragraph that clearly states their claim and defends it with organized, cited evidence. Students often find it challenging to move beyond simply stating opinions like "I think Ms. Hart is" to using evidence effectively. By practicing this SEP in a low-stress, engaging context, they learn:

Welcome to Our SEP Series: Exploring Science PracticesOver the next few weeks, we’ll be diving into the Science and Engineering Practices (SEPs), exploring how each one plays a crucial role in developing critical thinking, problem-solving, and analytical skills in science education. These practices are central to how we learn and apply scientific concepts in the classroom. What Are SEPs?The Science and Engineering Practices are intentionally scaffolded across grade levels. This progression ensures students continuously deepen their understanding and application of modeling as their cognitive skills grow. The eight SEPs are:
Why SEPs Matter in Middle School Science Middle school is a pivotal time for students to develop problem-solving and critical thinking skills. SEPs provide a framework for students to experience science firsthand—engaging in activities that challenge them to think like scientists and engineers. Whether they are building models, conducting investigations, or analyzing data, students are practicing real-world skills that will benefit them in every aspect of their lives. By emphasizing the SEPs in middle school, students not only gain knowledge but also develop the tools to think critically, ask meaningful questions, and solve problems in innovative ways. These skills are essential not only for science but for life in general. This week, we’re focusing on Developing and Using Models—a cornerstone practice that helps students visualize, test, and refine ideas. Whether they're building a prototype, drawing a diagram, or using a simulation, modeling allows students to explore complex scientific phenomena in tangible and meaningful ways. What Does Developing and Using Models Mean? Models are simplified representations of complex objects, systems, or phenomena. These might include physical replicas, diagrams, graphs, simulations, or conceptual explanations. At the middle school level, students are expected to:
Common Challenges for Middle School Students
Models in Action: Investigating Human Leg Anatomy
Empowering Students Through Models Developing and Using Models isn’t just a checkbox on a science standard it’s a powerful lens through which students make sense of the world. Through modeling, students deepen their understanding, apply critical thinking, and engage in authentic scientific practices.
From the chicken wing dissection to weather system models and energy diagrams, students in our classroom learn by doing. They’re not just memorizing facts, they're building explanations, testing predictions, and revising their thinking as they uncover new evidence. By teaching students to think with models, we equip them with skills that will serve them in high school, in future STEM careers, and as scientifically literate citizens of the world. Why Hands-On Learning is the Secret to Unlocking Complex Science Concept Have you ever wondered why students learn science better when they can get their hands dirty? Hands-on learning is not just fun it’s an essential tool for helping middle schoolers master complex scientific concepts. By actively engaging with the material, students make connections that go beyond textbooks. Here’s a look at three exciting hands-on projects from my classroom that demonstrate why interactive learning is key to deepening understanding in science. Weather Water Tanks: A Fun Dive into Density and Fluid BehaviorIn the Weather Water Tanks experiment, students explore how temperature affects the density of fluids and how fluids with different densities interact. By mixing warm water with cold water, students can directly observe the effects of changing temperatures, helping them better understand concepts such as density, thermal energy, and fluid dynamics. This hands-on activity makes abstract scientific principles more accessible by allowing students to manipulate variables and see the results for themselves. Instead of just reading about density in a textbook, they experience it firsthand, strengthening their understanding of how temperature affects fluid behavior. What did students learn?
Save the Penguin: Insulating Against the HeatThe Save the Penguin project challenges students to design and test insulation structures to protect a “penguin” (a small ice cube) from melting in a cold environment. By experimenting with various materials like foam, cotton, and aluminum foil, students learn about heat transfer, insulation, and thermal energy. Not only does this project teach students valuable scientific principles, but it also connects to real-world issues, such as climate change and its impact on animal habitats. As students build their insulating structures, they develop an understanding of how rising temperatures affect ecosystems, fostering both scientific and environmental awareness. Who is Ms. Hart? The Great MBTI MysteryIn the Who is Ms. Hart? project, students gather evidence to guess my MBTI personality type based on various aspects of my life—such as my teaching style, hobbies, and past student feedback. They work in groups to collect six different forms of evidence, including video clips, readings, and a room walk, and then use the Claim, Evidence, Reasoning (CER) framework to analyze their findings. The ultimate goal is for students to make an evidence-based claim about what my MBTI type might be. This project is not only a fun and engaging introduction to the scientific method but also teaches students how to collect data, interpret it, and construct arguments based on evidence. By applying the CER framework to guess my MBTI, students practice critical thinking, observation, and scientific reasoning in a personal and relatable way. What did students learn?
Why Hands-On Learning WorksThese projects highlight why hands-on learning is essential for understanding complex scientific concepts:
Reflecting on the 2024-25 High School Volleyball Season: Growth, Resilience, and a First Gold Medal10/28/2024 This year’s high school volleyball season was unforgettable, and not just for the wins. As a coach and classroom teacher, I had the privilege of watching both our varsity and JV teams grow in incredible ways. It was a season of firsts, hard work, and unexpected bonds. Despite injuries and setbacks, both teams rallied to improve, eventually bringing home gold medals from KISAC—and for me, it was my first gold here at KISJ. Rising Above Challenges and Celebrating Milestones Injuries hit hard this season, from broken noses to sprained ankles. It could have been enough to shake any team, but our players rose to the occasion. They stepped up in new roles, adapted quickly, and learned to trust each other in ways they hadn’t before. Watching them dig deep and build on one another’s strengths reminded me that success isn’t about a perfect season but about the resilience we build along the way. Every match prepared us for the ultimate victory at KISAC, where both teams delivered outstanding performances to bring home gold. Winning my first gold medal here at KISJ was a special moment, made even more meaningful by witnessing how far these players had come. It was a season filled with personal and team milestones, each one building toward that shared triumph on the court. Coaching: A New Perspective on Connection and Growth
A Season of Skill Development and Connection Both JV and varsity worked hard to grow their skills, with JV focusing on foundational techniques and varsity building advanced tactics and court awareness. This development wasn’t easy, and it didn’t happen overnight, but each player pushed themselves to learn and improve. Practices became spaces of dedication, with everyone contributing to the team’s progress, learning new plays, and perfecting their game. Their work paid off when it mattered most, with both teams finding their rhythm and delivering impressive performances to earn those KISAC golds. More Than Teammates: Building a Sisterhood
As an American teacher working at an international school in Jeju, South Korea, I’ve come to appreciate the unique blend of cultures that surrounds me daily. Teaching 6th-grade science is an exciting adventure on its own. Still, the international setting offers me new perspectives that continually shape my outlook on life. With the Chuseok holiday break just around the corner, I’ve found myself thinking more about gratitude—both in the context of this Korean holiday and my personal journey here. Chuseok, often described as Korea’s Thanksgiving, is when families come together to celebrate the autumn harvest and honor their ancestors. It’s a major holiday in Korea, and its anticipation is palpable in the air, even in our international school. Students talk about going home to visit family, helping prepare traditional foods like 송편 songpyeon (rice cakes), and paying respects to their ancestors.
In my 6th-grade science class, teaching gratitude isn’t on the syllabus, but it finds its way into our lessons. Whether we’re studying ecosystems, discussing energy cycles, or completing experiments, I often see my students express their own forms of gratitude—sometimes, it’s for the opportunity to learn something new. Other times, it’s in small gestures, like sharing materials with classmates or helping one another solve a tricky problem. As a teacher, these moments remind me to be grateful for the curiosity and enthusiasm my students bring to the classroom. We’re constantly learning from one another, whether through science or simply through everyday interactions. I’m grateful for the opportunity to witness these moments of growth and collaboration, which make the classroom a richer environment. One of the greatest sources of gratitude for me comes from my students. Sixth graders are at an age where they are beginning to understand more about the world and their place in it. Teaching science allows me to fuel their sense of wonder and curiosity, something I consider a privilege. When they get excited about an experiment or ask a question that makes me think, it reminds me why I became a teacher in the first place.
As Chuseok approaches, I’m filled with gratitude for this chapter of my life. Teaching 6th-grade science in an international school on Jeju Island has been a life-changing experience that I wouldn’t trade for anything. The students, the school, and the island itself have all left a lasting impact on me, and I feel fortunate to be part of this community. As my students head home to celebrate with their families, and I take some time to reflect on my own journey, I’ll be thinking about the lessons that gratitude and Chuseok have taught me—lessons that I’ll carry with me long after the holiday has passed.
