What’s Taught
Simple unplugged coding activities
The Science Behind Hour of Code Week
Hour of Code Week has deep scientific roots. Hour of Code Week gets kids coding with fun, unplugged activities. No computer required, just logic puzzles and sequencing games that build early coding skills. The discovery and understanding underlying this event represents some of the most important intellectual advances in human history.
Scientists, mathematicians, naturalists, and explorers contributed to what we now celebrate on this day. Their curiosity, and their willingness to question accepted wisdom, changed how we see the world.
Teaching the history of this scientific concept helps students understand that science isn't a fixed body of facts. It's a living conversation across generations, one that students can join right now.
Why Hour of Code Week Belongs in Every Classroom
Science literacy is one of the most critical skills students in Kindergarten–Grade 1 can develop. Observing, questioning, experimenting, and explaining, these habits of mind apply far beyond the science classroom.
Hour of Code Week provides a compelling hook for inquiry. Whether your classroom has a full lab setup or a single windowsill, this event invites students to engage with the natural and designed world with genuine curiosity.
Teaching science is also teaching humility, the understanding that we don't know everything, that questions matter as much as answers, and that being wrong is part of the process. These are lessons that last a lifetime.
How to Teach Hour of Code Week by Grade Level
Kindergarten
For kindergarteners, make Hour of Code Week concrete and sensory. Use picture books, puppets, songs, and simple art activities to introduce the key concept. Focus on one big idea, "we are all connected" or "the world is changing", and return to it throughout the day through different experiences.
Grade 1
First graders are ready for simple explanations and structured discussion. Anchor Hour of Code Week with a shared read-aloud, then use sentence frames ("I notice… I wonder… This makes me think…") to guide responses. Drawing and labeling lets emergent writers participate fully.
Hour of Code Week Classroom Activities
Guided Inquiry Investigation
Students follow the scientific method to investigate a question connected to Hour of Code Week: ask a question, make a prediction, design a test, collect data, and draw conclusions. Even simple investigations build powerful scientific thinking.
Kindergarten–Grade 1STEM Design Challenge
Present a real-world problem related to Hour of Code Week. Students work in teams to design, build, test, and improve a solution using provided materials. Debrief focuses on the engineering design process, not just the outcome.
Grades 2–5Scientist Biography Study
Students research a scientist connected to the theme of Hour of Code Week. They create a biography poster or "scientist trading card" and present it to the class. Discuss: what questions drove this scientist? What obstacles did they face?
Grades 2–5Nature Sketchbook
Students make detailed observational drawings of natural objects connected to Hour of Code Week's theme, plants, weather patterns, insects, rocks. They label parts and add one question per drawing. Builds observation skills and scientific vocabulary.
Kindergarten–Grade 1Concept Mapping
Students create a concept map showing how key science ideas from Hour of Code Week connect to each other and to things they already know. This metacognitive tool shows students their own growing understanding.
Grades 2–5
Hour of Code Week Games & Interactive Ideas
Science 20 Questions
One student thinks of a science concept, object, or organism connected to Hour of Code Week's theme. Classmates ask yes/no questions to identify it in 20 questions or fewer. Builds scientific vocabulary and deductive reasoning.
Kindergarten–Grade 1Lab Prediction Challenge
Before a demonstration or experiment, all students record their predictions. Reveal results and count how many students predicted correctly. Discuss: what prior knowledge helped? What surprised you? Builds scientific reasoning.
Kindergarten–Grade 1Science Pictionary
Teams draw and guess science vocabulary, diagrams, or concepts related to Hour of Code Week. Students must illustrate abstract concepts, which reveals and deepens understanding in ways that writing alone cannot.
Kindergarten–Grade 1STEM Feud
Modeled after Family Feud, ask questions where teams guess the most common answers about science topics related to Hour of Code Week. "Name a thing that needs sunlight to survive." Great for activating prior knowledge and misconceptions.
