Unit 01 · Observation & Asking Questions

This is where every scientist starts and where this whole pack begins: looking closely, writing down exactly what is there, and turning a plain “huh, why did that happen?” into a question you can actually test. A student watches a bean seedling lean toward the window, times how long an ice cube takes to melt, or measures how far a paper airplane flies — and learns to separate what they saw from what they guessed. Mastery means your notebook records the world honestly and your questions are ones an experiment could answer.

CriterionNot yetApproachingMastered
Careful observation (qualitative & quantitative)Writes vague notes (“it changed”) or records conclusions instead of what was seen.Describes what happened but mixes in guesses, or skips the numbers a ruler or stopwatch would give.Records precise, separated observations — “the left seedling is 4 cm taller and leaning toward the window” — with no conclusions mixed in.
Asking testable questionsAsks questions that can’t be investigated (“which plant is prettier?”) or asks none at all.Raises a real curiosity but leaves it too broad to test (“what helps plants grow?”).Turns a curiosity into a sharp, investigable question: “does a seedling grow taller in the window or under the lamp?”
Forming a hypothesisOffers a vague guess or a restatement of the question, with nothing that could be proven wrong.States a prediction but leaves out the “if/then” or a clear way it could fail.States a testable, falsifiable if/then prediction: “if the ramp is steeper, then the toy car will roll farther.”
Identifying variablesCannot say what is being changed or what is being measured.Names one variable but confuses what is changed with what is measured, or misses what to hold steady.Names what could be changed (ramp height), what will be measured (distance), and what to keep the same — clearly and out loud.
Observation vs. inferenceReports opinions or interpretations as if they were facts (“the car likes the smooth floor”).Usually tells them apart but slips an interpretation into the observation list.Cleanly labels each note: “observation — the tablet fizzed faster in warm water; inference — heat probably speeds it up.”
Integration (cross-domain)Treats the skill as isolated; makes no connection to the year’s anchor.Mentions the Semmelweis story but cannot say what his careful observation had to do with this skill.Connects observing and questioning to Semmelweis — careful records of who washed hands and who didn’t — across History · Reading · Writing, and defends why it matters.
Mastered sounds like

“The left seedling is 4 cm taller than the right one and leaning toward the window — that’s what I saw. So my question is: does a seedling really grow toward the light, or was it just that plant? My hypothesis is, if I turn the pot around, then the new growth will bend back toward the window. Light is what I’m changing; the lean is what I’ll measure.”

Not yet sounds like

“Um… the plant looks better? I think it likes the window. That’s just kind of how plants are.”

How mastery works

You demonstrate this unit through watched observation and questioning tasks — describing what happens at the bench, then turning it into a testable question — plus short oral checks where you reason aloud. Not a multiple-choice test. A criterion counts as mastered only when a guide can watch you do it: observe carefully, separate what you saw from what you guessed, and ask a question an experiment could answer. Mastery is demonstrated, not awarded.
