0–5🎯 Hook"What do you notice about this bag of objects?" Pass around sorting bag.
5–18📖 Lesson 1–2Looking vs. observing · Attributes · Single & two-attribute sorting
18–35🎮 ActivityObject Sort Challenge — sort 20+ objects 3 different ways
35–45📖 Lesson 3–4Patterns in everyday life · Observation vs. opinion · Observation journal
45–53✍️ JournalStudents write 3 observations about one object — no opinions allowed
53–58🔁 Recap"One thing you noticed today that you wouldn't have noticed before?"
58–60👋 ClosePreview Session 2: "Next time — questions that data can answer."
Pacing note: The Object Sort is the heart of the session. Don't rush it — let students discover that the same objects can be sorted many ways. That surprise IS the lesson.
📦 Materials Needed
Prepare before class:
20–30 small objects per group (buttons, coins, shells, blocks, bottle caps) Sorting mats (plain paper or trays) Colored pencils Pencils Blank paper for observation journals 1 "mystery bag" per group (paper bag with objects inside)
💡 Tip: Raid your desk drawer — paper clips, erasers, sticky notes, coins all work perfectly.
📚 Key Vocabulary
Observation — noticing details carefully and on purpose
Attribute — a specific characteristic (color, size, shape, texture)
Sorting — grouping objects by shared attributes
Pattern — something that repeats or follows a rule
Category — a named group that objects belong to
Opinion — a judgment or feeling (NOT an observation)
💬 Discussion Questions + Teacher Notes
  • "What's the difference between looking at something and really observing it?"
    → Looking is passive. Observing is active — on purpose, with attention to detail. Use the hook bag to show: first glance vs. careful examination.
  • "How many ways could you sort these objects?"
    → No limit! Same objects sorted by color, then by size, then by texture. Point out: one object can belong to many categories depending on the rule.
  • "Is 'this rock is pretty' an observation?"
    → No — it's an opinion. "This rock is gray and has a rough texture" IS an observation. Anchor the difference early and refer back to it all session.
  • "Where do you see patterns every day?"
    → Seasons, school schedule, traffic lights, meal times, heartbeat. Patterns are everywhere — data science starts with noticing them.
  • "Why does a scientist need to observe before asking questions?"
    → You can't ask a useful question about something you haven't looked at carefully. Observation is step one of the data cycle.
🎮 Object Sort Challenge — Setup Guide
Groups of 3–4 students. Each group gets a bag of 20–30 mixed objects. Task: sort the same objects 3 different ways.
Steps:
  1. Groups open bags — 2 min of free exploration (touch, look)
  2. Sort #1: by one attribute they choose — label each group
  3. Sort #2: mix back up — sort by a different attribute
  4. Sort #3: try two attributes at once (big AND red)
  5. Gallery walk: groups see each other's sorts — discuss differences
Key debrief question: "Did your objects end up in different groups each time? What does that tell you about how we organize information?"
💡 Let students name their own categories. "Shiny things" is just as valid as "metal." Accept all attribute-based reasoning.
🎯 Opening Hook
Pass a bag of objects to the front row. Don't say anything — just wait.
"What do you notice?"
Accept ALL responses. Then ask: "What would you need to look at MORE carefully?" Give 1 extra minute to observe.
→ This sets the session's tone: slow down and pay attention.
✍️ Journal Prompt
Write on board:
"Choose one object from today. Write 3 observations about it. Use words AND a sketch. No opinions allowed!"
8 min quiet writing. Check: are students writing facts or feelings?
Good observation: "The button is round, blue, and has 4 holes."
Opinion (redirect): "The button is cute."
🧠 ND-Friendly Tips
  • Hands before words — Put objects in hands before giving any definitions. Tactile first, vocabulary second.
  • Movement = reset — The gallery walk and sort activities give physical learners an anchor.
  • Accept all attributes — "Smells like pencil case" is a valid observation. Don't narrow too fast.
  • Pair for journal — If a student struggles to write alone, allow quiet partner dictation.
  • Preview the sort — Tell students before they begin: "You'll sort 3 times. First sort in 5 minutes."
