Reigate Grammar School VietnamHanoi, Vietnam
Which wrapping material could keep an ice cube from melting as quickly? Use a Primary inquiry to compare predictions with observations. Bring your PYP unit, year group and safe test setup to PLAI™, then review a draft that asks learners what their evidence supports.

Give the question a test learners can explain.
Reigate Grammar School Vietnam uses the IB Primary Years Programme in its Preparatory School. Connect a materials investigation to the unit you actually teach: learners predict which wrapping might slow melting, help plan a fair comparison and revisit their explanation after observing the result.

What can you tell me about Reigate Grammar School Vietnam and its IB Primary Years Programme? Use public sources, recognise its former name International School of Vietnam, and distinguish the Primary programme from secondary qualifications. Ask for my year group, unit of inquiry and learning objective before suggesting a task. Flag anything you cannot confirm.
School context
Reigate Grammar School Vietnam
Curriculum IB PYP and Diploma; Cambridge IGCSE
Topic focus investigating which wrapping material slows the melting of ice
What are you preparing next?
Before choosing a material, agree what makes the test fair.
Offer two wrapping materials and ask learners to predict which could slow melting. Agree what must stay the same, including the amount of ice, the containers, the location and the observation time. Compare the result with the prediction, then ask what one trial can and cannot tell them.
Your lesson prompt
Help me plan a Primary materials investigation for my confirmed PYP year group, unit and objective. Ask for my materials, safe setup, class experience and available time. Compare two wrapping materials around identical containers holding equal amounts of ice. Keep the location and observation time consistent, with an unwrapped comparison if appropriate. Have learners predict, identify what stays the same, record observations and revisit a claim. Use teacher-supervised handling; do not invent results or a prescribed Reigate unit. Include teacher-check notes on fair comparisons and heat moving from warmer surroundings towards the ice.
Plan the comparison before testing.
Inspect the supervised Year 5 investigation report: question, prediction, variables, repeated results, graph and conclusion. The supplied example concerns dissolving sugar. For this page’s task, prepare the material around investigating which wrapping material slows the melting of ice.
Open the worksheet prompt
Help me prepare an original task about investigating which wrapping material slows the melting of ice for my confirmed class. I will supply the source content. Use Sugar dissolving investigation report as a model for the teaching structure. Ask for my year group, goal and prior learning. Check the new subject content and age suitability, offer optional support and leave an independent explanation. Keep source facts distinct from this new task and do not infer school criteria.
Refine the worksheet
Review the new investigating which wrapping material slows the melting of ice task for my confirmed class. Check the subject content, reading load and response space. Add optional support while keeping an independent explanation. Prepare a separate teacher-approved investigation for the current topic. Keep the method, equipment, safety and expected reading level suitable for the confirmed year group.
Use the source as a teaching model, then review the new task for your confirmed class.
Check the next explanation.
For investigating which wrapping material slows the melting of ice, decide what pupils must explain independently. Prepare a separate teacher-approved investigation for the current topic. Keep the method, equipment, safety and expected reading level suitable for the confirmed year group.

Questions about using PLAI™ at Reigate Grammar School Vietnam
Does this belong to a particular PYP unit?
This is a suggested investigation, not a named Reigate unit. Add your actual unit of inquiry, year-group objective and current learning context. Decide whether the comparison helps learners explore the idea your class is working on.
What if the result does not match the prediction?
Ask learners to describe the observation before explaining it. Check whether the comparison was fair, consider repeating it and keep uncertainty visible. A changed claim supported by evidence can be more useful than a prediction that happened to be right.
Do learners need exact measurements?
Choose observations or measurements that fit your objective and year group. Keep the starting conditions and observation time consistent. If using measurements, include units and check the method before asking learners to interpret a difference.
Are the recordings specific to this school?
The recordings show general PLAI™ worksheet workflows. They do not show this task or work from Reigate Grammar School Vietnam. The prompts here are suggested starting points to adapt and review for your class.
Is this an official school page?
This is an independent TopSchool Teachers Hub page. It does not establish school endorsement or a partnership.
Does selecting my school give me school access?
Selecting a school or sharing a public link does not verify membership or grant access to private materials. Follow your school’s access arrangements.
Bring a question your class can test.
Start with the unit, materials and conditions you have. Use PLAI™ to shape a draft that keeps predictions, observations and explanations distinct, then check it before teaching.
