Science Can Be Revised
Scientific knowledge is provisional — it is the best current explanation based on available evidence, and it can and should be revised when better evidence arrives

Teaching Table
Set out your lesson
Use evidence, not confidence or authority alone, to decide when to revise an explanation and when to investigate further.
Ask for the difference between seeing two events together and showing that one caused the other. If this is unclear, use Guided as supported reasoning before attempting Try.
Pause the fresh check. Revisit the named prerequisite or repeat the Show with smaller steps; record supported practice rather than an independent result. Authored predecessor existence never proves this learner is ready.
Allow 25 minutes. All investigation records are invented for reasoning; none are reported as actual learner or published experimental observations. Use the supplied historical card and data table only. No science equipment, internet activity or printing is required. Keep the learner’s own answers separate from the fictional records.
Use paper or the supplied screen materials in a comfortable place. No special equipment or purchase is needed. Stop or take a break when wanted.
Record the learner’s actual words or work, task ID and any help. Do not prefill success. Allow oral, pointing or written responses as appropriate; oral independent reasoning is not automatically supported. Copied/scribed text is not independent composition or handwriting. No name, account, upload or real family record is required.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
No real investigation is performed. Fictional records cannot satisfy a requirement to collect actual observations.
Finite task opportunities, not learner mastery or universal canonical coverage.
Use the supplied materials on screen or print one current sheet; physical printing can vary.
Record the actual response and assistance; completing a task does not establish mastery.
Use paper or the supplied screen materials in a comfortable place. No special equipment or purchase is needed. Stop or take a break when wanted.
Record the learner’s actual words or work, task ID and any help. Do not prefill success. Allow oral, pointing or written responses as appropriate; oral independent reasoning is not automatically supported. Copied/scribed text is not independent composition or handwriting. No name, account, upload or real family record is required.

Check understanding
- Give an example of a scientific idea that changed when new evidence was found — e.g. people once thought the Sun orbited the Earth
- Explain that scientists update their ideas when experiments give unexpected results, and that this is a strength not a weakness
- Describe why it is important to keep testing ideas rather than just accepting them because an expert said so
“Does your child understand that scientific facts can be revised as new discoveries are made — and that this is science working properly, not a sign that scientists were wrong?”
