See it before you commit

Look inside the Physical Science pack.

No sign-up, no email required. Here is a real week, a real rubric, a real lab-notebook page, and a real demonstration — the actual materials, not a brochure. Every sample links to the full artifact it’s drawn from.

1 · A real week

One week, two days at the bench.

The course runs on a two-day pulse — about two hours a day, across roughly 32 weeks. Here is week one of Unit 1 — Matter & Its Properties: the student measures matter for real before a single definition is memorized.

Concept Day · ~2 hrs
Meet matter through the properties you can measure — mass, volume, and density — and sort the world into pure substances and mixtures. Work through why a heavy object can still float while a light one sinks: it’s density, not weight.
  • Mass, volume & density
  • States of matter & changes of state
  • Mixtures vs. pure substances
Experiment Day · ~2 hrs
Measure the mass of each sample on a balance and its volume by ruler or water displacement, then calculate density and predict whether it floats or sinks — before dropping it in the tank to check.
  • Measure mass, volume & density
  • Predict float vs. sink from density
  • Report data with correct units

2 · A real rubric

How “mastered” is actually judged.

Every skill is scored at one of three levels against a published bar — no points, no curve. Here is one criterion from the Matter & Its Properties rubric — density — shown exactly the way a parent or guide reads it:

LevelWhat it looks like — “Measure density, then predict float or sink”
DevelopingThinks heavier objects always sink.
ProficientKnows density is mass over volume but cannot use it to predict floating or sinking.
MasteryCalculates density from measured mass and volume and uses it to predict whether an object floats or sinks.

3 · A real lab-notebook page

The artifact a student builds, keeps, and defends.

The lab notebook isn’t busywork — it’s the primary record, kept in pen at the bench and defended out loud. Here is one real Experiment Day, every section kept live — note the struck-through timing slip and the honest sources of error.

Sept 12 Does a heavier cart roll down faster?
Question
Does adding mass make a cart reach the bottom of a ramp sooner?
Hypothesis
I think heavier will be faster because it feels like it should push harder.
Materials
Ramp at a fixed angle; cart; three masses; stopwatch; meter stick.
Procedure
1. Release the cart from the top line. 2. Time it to the bottom. 3. Add mass and repeat — 5 runs each. ↪ started the watch late on run 1 — threw it out
Observations & data
Added mass (g)Time (s)
01.42
1001.40
2001.43
Labeled sketch: the cart on the ramp, start and finish lines marked.
Analysis
The times barely changed — within stopwatch error. Mass did not speed the cart up; gravity accelerates them all the same down the ramp.
Conclusion
A heavier cart does not roll down faster — my hypothesis was wrong. With friction small, mass doesn’t change the time.
Sources of error
Stopwatch reaction time (~0.2 s) is bigger than the differences I saw, so I can’t claim a real difference. Averaging 5 runs helped.
A model entry. One Experiment Day, kept live at the bench — graded against seven habits and defended out loud.
  • Dated & titled entries
  • A testable question & hypothesis
  • Units on every number
  • Significant figures, honestly reported
  • Calculations shown, not just answers
  • Pen in real time — struck, not erased
  • Error analysis with direction & size

4 · A real demonstration

The moment that can’t be faked.

Three times across the year, a student performs and defends a demonstration — standing with their own work and reasoning aloud while an adult asks unscripted follow-ups. In the timed prediction-and-test, they predict a physical outcome from their own measurements, then run it live and account for the difference.

“The steel bolt masses 31 g and displaced 4 mL of water, so its density is about 7.8 g/mL — well over water’s 1.0 — so I predicted it sinks. It did. The cork came out under 1.0, so I called it a float, and it floated.”

A passing answer from the timed prediction-and-test — reasoning from real measurements, not guessing from weight.

5 · What you’d print

The whole pack, ready for a binder.

Everything here is on the web to read — and every rubric, checklist, and guide also has a print-ready packet version, formatted 8.5×11 for a clipboard or a three-ring binder. You assemble the student’s binder from the pack itself; there’s nothing else to buy to hold it in your hands. We’ve put them all in binder order on one page: Assemble the Physical Science binder →
