Health claims need careful evidence

1 · Learn

Food, movement, rest and substances taken into the body can affect how it functions. Medicines are drugs used for particular purposes under appropriate adult and professional guidance; some substances can harm the body. 'Natural' does not automatically mean safe.

A claim about health needs trustworthy evidence, not just an advertisement or a single person's story. Never experiment with unknown substances or change medicine because of a school activity.

Key words and supplied examples.

2 · Worked example

A fictional advert says one drink makes everyone run twice as fast. I ask how that was tested, who was compared and whether the evidence supports such a sweeping claim.

3 · Your turn

Does one testimonial prove the drink works for everybody?

Check your answer

No. One story cannot establish the effect for everyone and may omit other explanations.

4 · Apply your learning

Compare two invented health adverts and list questions about their evidence, without using any products.

Adult guidance and safety

No dosing, diagnosis or personalised health advice. Medicines remain under the learner's responsible adults and healthcare professionals.

Check a calculation · Year 5 onward

Use this only when your teacher or adult allows a calculator for the task. Show your thinking first. It does not replace mental or written arithmetic and does not mark your lesson answer.

My observation notebook

With an adult, look at a safe real example or a checked photograph. Name the example and say which you used. Record what you actually notice. Do not taste plants or materials, approach unknown animals or invent missing observations.

Ask your teacher for support with the method and recording. A prediction is what you think might happen; an observation is what you actually see, hear or feel safely.
