Cool-Water Design Investigation
Is this the right resource?
- Audience / fit
- Intended Grade 6 science; selected Grades 6–8 standards ideas
- Teaching or planning target
- Plan a fair cool-water comparison, record baseline and prototype trials, then redesign and retest. Includes a complete supplied-data alternative.
- Essential prerequisites
- Read °C and time, subtract decimal readings, distinguish temperature from energy, and follow comparison conditions. Measuring 150 mL and safe probe placement are also required for practical work.
- Preparation
- Review the operational card and verify equipment/conditions before practical work; preparation time depends on local equipment. Supplied data needs only selected copies.
- Use time
- Practical: about 74 minutes per phase, with supervised continuation if needed (planning estimate). Supplied data: split comparison/proposal and retest/reassessment into separate stages; timing varies.
- Materials
- Supplied data: paper, pencil and Part 1, then Part 2. Practical: matching stable cups/covers, suitable non-glass probes, air thermometer, 150 mL cool water per cup, marked measure, timer, tray, probe supports, pre-cut felt and tape. Check the operational card before procurement or water use.
- What to print
- Use the stage-specific student choices below and the matching teacher guide. Give independent, new-evidence and later-assessment pages only at their intended stage.
Choose practical work or supplied data
Practical: assemble and compare
Adult supervision, checked equipment and qualifying conditions are required. Read the complete operational teacher guide before preparing materials.
Practical first comparison: directions and blank trials · PDF (11 pages)
Supplied data: compare, propose, then reassess
No equipment needed. The records are fictional constructed examples, not measurements from a class.
First: print Part 1, compare and record the proposal · PDF (7 pages)
Then: Part 2, reassess the specified retest record · PDF (3 pages)
Collect or retain each proposal before distributing Part 2. Keep the redesign results unseen until learners commit a proposed change. These values describe the specified fictional design, not the learner’s unbuilt proposal.
Teacher setup, procurement, complete keys and alternatives · PDF (17 pages)
For practical work, use the first-comparison directions and blank records; constructed first-trial and retest results are excluded. Read the current complete operational teacher guide before preparing equipment. Keep three fresh paired trials in each phase. Use the separate supplied-data Part 1 and Part 2 if equipment or conditions are unsuitable, and label that route as analysis of constructed records.

Learning target: Compare a baseline and prototype with cool water, then redesign and retest against an identified reference.
Use written, oral or labeled representations when they show the intended reasoning. This resource addresses selected standards ideas; supplied-data analysis does not establish actual construction or testing.
Prerequisites: Read °C/time and calculate change; measure 150 mL; follow paired-condition and probe-position instructions. The brief, assembly instructions and supplied-data teaching model provide the method bridge.
Materials: Per group: three identical stable 250–300 mL plastic cups with matching loose covers and existing probe slots; two suitable non-glass immersion probes; a classroom air instrument; 150 mL cool water per cup per fresh trial; a marked measure, timer, spill tray, probe supports, clean pre-cut 26 × 6 cm felt sheets and pre-cut tape. See the operational card for quantities, conditions and equipment checks. Paper and pencil support the supplied-data fallback.

Formats and all files
Complete reference files may include teaching, independent tasks, later evidence or teacher answers. Keep them with the teacher; use the separate stage selections above for handouts.
For supplied data, hand out Part 1 before Part 2. Full packets, combined reflection selections and mixed archives include later results: keep them with the teacher and give only the phase in use. Teacher keys and later checks stay separate.
