Start Here · Five-resource route

Use this guide for the five-resource sequence. Each resource has student tasks, a separate teacher guide, focused follow-up tasks and a later check.

Choose a sequence or enter from a response

Read Temperature Data Before Explaining It: read measurements—headings,units,time,starts,change. Was It a Fair Comparison?: evaluate comparison conditions—question,confounds,matched repair,recording. Start Here: support a design choice—paired evidence across trials and limits. Explain Why the Temperature Changed: explain the pattern—sample/surroundings,net-transfer direction and scientific connection. Revise a Claim When Evidence Changes: revise a particular claim—compare new conditions/evidence and retain,narrow,change or remain uncertain.

Each resource has its own prerequisite bridge. The sequence helps connect ideas but is not required before entering a kit. Check the bridge; clarify task/language/representation access. A correct selected design does not by itself show explanation; a blank response does not identify a science difficulty.

Prepare and print

Required: paper and pencil. Optional: calculator,number line,pointing,projection,oral response or labeled representation. Read the one-page teacher quick start and relevant key. Print student files only,keeping keys separate. Use actual standalone selections listed here,not the whole packet when exposure/reveal matters.

Equipment-free supplied-data analysis is not evidence of conducting an investigation or designing,constructing and testing a physical device.

Vocabulary and scientific boundaries

Observation: a supplied reading at a stated time. Evidence: a relevant observation selected for a question. Explanation: connect that evidence to a scientific idea. Temperature: reading in°C here;change: start-to-finish difference with direction. Warming: higher final;cooling: lower final. Sample: matter studied;surroundings: parts outside it;net: overall transfer accounting for opposite directions.

Matched comparison: relevant conditions agree for the intended question. Confound: another relevant difference mixes possible effects. Independent trial: a fresh comparison;repeated time readings from one sample are one run. Complete design: construction choices together,not an isolated material property. Claim scope: conditions/results the statement actually concerns.

Revision can retain a bounded claim,narrow its scope,change a conclusion or withhold confidence. Decisions depend on exact wording and comparability. A new result does not require reversal. One design’s changed-condition record does not rank it against an untested design. Keep contrary raw records;an exclusion needs a procedural reason,not convenience.

A temperature reading is not total energy. Type, state and amount of matter also affect total energy. For these passive, single-phase cases, net thermal-energy transfer is from warmer parts toward cooler parts. An arrow represents that net transfer, not a substance called cold or an individual particle path. Temperature readings alone do not isolate conduction, convection or radiation, calculate total transferred energy, or show an instantaneous transfer rate. Limiting warming is not cooling; limiting transfer is not stopping it.

At idealized uniform equal temperatures,with no other input/output or phase change,there is no net thermal-energy transfer driven by a temperature difference;particles at 22°C still move. One unchanged reading does not establish equilibrium or absent particle motion.

Small/variable differences plus unknown accuracy can leave a comparison uncertain;overlap does not prove identical performance. Display precision is not accuracy. More trials do not automatically remove systematic bias. No joules,statistical significance or total-energy ratios from Celsius numbers are required.

Every dataset is constructed teaching data,not experiment measurements or computer simulation. All fictional responses are labeled. The Read Temperature Data Before Explaining It graph repeats its model table;the Explain Why the Temperature Changed arrow is an explanatory model,not an observed pathway. Text alternatives give equivalent information,not assessment answers.

Print choices · First three resources

In the classroom ZIP, the Read temperature data, Compare test conditions and Support a design choice folders each contain Student tasks, Teacher guide and Print choices folders. Choose the full student packet or the separate student selection you need. Each resource also has separate print-choice downloads; use the activity titles below to select them.

Print choices and new-evidence sequence

The Explain temperature change and Revise a claim folders each contain Student tasks, Teacher guide and Print choices. PDF, editable Word and readable HTML versions are supplied. Match each separate student selection to the keys and full-packet page references in its teacher quick start.

Revise a Claim When Evidence Changes: print one-sided;hand out initial record first;record the original claim;then hand out the separate new-evidence page. Keep both visible for revision. The revision record has seven fields;teacher revision record has a completed example. Student full packet/download preview is not a reveal-safe whole-class handout.

After Independent task,use a still-unseen Later Check;after reteach,use its supplied fresh recheck. Freshness is conditional on actual prior exposure,not the filename. If all were shown,use as practice and document that limitation.
