Water Through Rock Lab

Sequence outcome: Test rocks for whether they let water through (permeability).

🎯 Learning objective: I can follow or direct a fixed water-passage method, record what reaches the collector and make a careful comparison of supplied samples.
✅ Success criteria
  • Follow the fixed volume, time and sealed-route instructions safely.
  • Record surface observations and water collected below in mL.
  • Compare the supplied samples under this method without claiming waterproof forever.

  1. In Explore, water measured underneath showed passage through; a wet top, absorption or edge leak did not prove the same thing.
  2. Prior week: point to or describe one useful model.
  3. Older learning: what makes an observation useful as evidence?
  4. Lead-in: what do you notice in today’s first picture?
New to this class, absent, or not sure? Everything needed is in the retrieval box above. Read it, point to it or ask a familiar adult to read it exactly.
◆ Supported
  1. Last lesson: point to TOP, INSIDE and BELOW on the water model.
  2. Last lesson: choose absorb or pass through for water that stops inside.
  3. Last lesson: point to the collector under the sample.
  4. Lead-in: choose mL or cm for the amount of water collected.
▲ Standard
  1. Last lesson: what observation directly showed passage through?
  2. Last lesson: why did an edge leak fail the method check?
  3. Last lesson: state one sample-specific conclusion rule.
  4. Lead-in: why must the collar stay sealed?
★ Stretch
  1. Last lesson: distinguish absorption from permeability evidence.
  2. Last lesson: explain why no passage in 120 seconds is not permanent waterproofing.
  3. Last lesson: identify one sample feature that may affect a result.
  4. Lead-in: predict how unequal thickness could weaken a sample comparison.

🌱 Starter · create the need to know

Water appears in the tray, but the collar leaked around the sample edge. What should the lab team record?

LOCAL VISUAL HOOK · FRAME 1
SEAL · water must not bypass the sample
collector · 0 mLsealed
Red seals stop water sneaking round the edge.
LOCAL VISUAL HOOK · FRAME 2
FOLLOW · same volume, same time
collector · 6 mLsealed10 mL on top · wait 120 s
Same amount of water, same time, for every sample.
LOCAL VISUAL HOOK · FRAME 3
RECORD · what reached the collector
collector · 2 mLedge leak ✗
An edge leak is not "water through rock". Record it as a fault, not a result.

Commit one first idea. Predictions are held, not marked. Pointing, selecting, saying or signing all count.

👩‍🏫 I Do · picture first

WHAT THIS MODEL HELPS US SEE

Check in order: seal held → 5 mL added → 120 s timed → collector read in mL → claim names supplied samples and method.

WHAT THIS MODEL DOES NOT SHOW

The lab uses a short classroom test on prepared samples. Natural variation, tiny cracks, sample thickness and sealing can affect results; the test is not a full building-performance check.

Step 1

Staff check the stable tray, pre-inspected matched pieces, sealed collar and clear collector. Pupils may operate only agreed safe steps or direct an adult.

Step 2

Add the fixed 5 mL with a needle-free tool, start the 120-second timer and observe top, underside and collector without moving the rig.

Step 3

Record the amount collected below in mL and note surface-only, absorbed or passed-through evidence. Record a fault instead of inventing a result.

Word help keeps the scientific term visible and adds a plain-language bridge.

💧 Sealed water bench · run the fixed method

Simulated for rehearsal. Same 10 mL, same 120 s, sealed edges. Only the sample changes.

collector · 0 mLt = 0 s
Pick a sample. Pour 10 mL. Then press +30 s four times.
Results: —
A wet top is not the same as water through. Only the collector counts. "Waterproof forever" is never a fair claim from 120 s.

Sample A collects 0.5 mL and Sample B collects 3.0 mL after the same 5 mL and 120-second method. Which comparison is supported?

Everyone commits before explanation.

Use a button, point, say/sign or let an adult operate the chosen button. A retry is information, not a penalty.

👩‍🏫 I Do 2 · connect the second idea

Connect the model to the second idea

Connection: the model is useful when its visible pattern is translated into a scientific explanation.
Connection 1

Compare collected-water values only after checking that both runs were valid. A lower value means less passage was observed in the stated time, not proven permanent waterproofing.

Connection 2

Notice what the fixed method tried to hold steady: starting volume, time, collar area and prepared thickness. Lessons 11–12 will name and test these method controls directly.

Connection 3

End with one careful sentence: Under this method, more water passed through supplied Sample __. One result set is useful evidence, but samples and repeats can vary.

MODEL STRENGTH

Check in order: seal held → 5 mL added → 120 s timed → collector read in mL → claim names supplied samples and method.

MODEL LIMIT

The lab uses a short classroom test on prepared samples. Natural variation, tiny cracks, sample thickness and sealing can affect results; the test is not a full building-performance check.

Follow or direct the fixed water-passage lab for supplied Samples A and B, or analyse the fixed equivalent records, then give a bounded comparison.

👐 Physical route

Staff-built sealed rigs; pre-inspected prepared sample pieces; stable trays; 5 mL needle-free pipettes or syringes; marked collectors; 120-second timer; wipes; result sheet.

Same outcome: I can follow or direct a fixed water-passage method, record what reaches the collector and make a careful comparison of supplied samples.

🖥 Offline digital / director route

Use the embedded fixed records: A = 0.5 mL and B = 3.0 mL after the same 5 mL and 120 seconds. Complete the same observation and comparison table.

Same evidence: Method checklist, surface/underside observation, collector values with mL, valid/fault decision, bounded comparison and one method-control question for Lessons 11–12.

🧰 Equipment / setupStaff-built sealed rigs; pre-inspected prepared sample pieces; stable trays; 5 mL needle-free pipettes or syringes; marked collectors; 120-second timer; wipes; result sheet.
🛡 Safety / sensoryOnly staff build and approve rigs. No hammering, chipping, scratching, licking, tasting, smelling or dust blowing. Keep samples on trays, contain spills, stop for leaks/damage/flaking/dust and wash hands. A director or fixed-data route is full participation.
🖥 Offline parityUse the embedded fixed records: A = 0.5 mL and B = 3.0 mL after the same 5 mL and 120 seconds. Complete the same observation and comparison table.
No-equipment/access route: Use printed method and result cards. A pupil sequences the method and directs an adult scribe; no handling is required.

◆ Supported

Sequence the fixed method, place A and B result cards and complete an oral, pointed or scribed comparison.

Scaffold

Use: A collected __ mL. B collected __ mL. More water passed through __ in this test.

▲ Standard

Record both valid results, reject one fault record and explain the sample comparison with a time limit.

Scaffold

Check seal, volume, time, collector and claim boundary in order.

★ Stretch

Evaluate how thickness, seal or natural variation could affect the comparison and propose one control to investigate in Lessons 11–12.

Scaffold

Do not rewrite the observed values; improve the future method.
