Teresa Tries a Fact-Check

M3-U3-L1-B Meet Teresa

One morning, she sees a post saying a food she eats daily “has been banned in Europe!”
It sounds dramatic — but is it true?

Teresa decides to check. She visits a website called PolitiFact and quickly finds out: the story is false. Now, Teresa always takes a moment to verify things before sharing them, and she teaches her friends how to do it too.

In this lesson, you’ll join Teresa in learning how to check the facts before clicking or sharing.

Trusted Tools for Fact-Checking

There are several reliable websites you can use to check whether a story, image, or post is true. These tools are trusted by journalists, educators, and everyday people — and they’re easy to use.

Here are some of the most useful fact-checking platforms you can explore:

International Platforms

  • EUfactcheck.eu – a European platform.
  • EDMO – a large European network of fact-checking organisations.
  • FactCheck.org – Verifies political and viral claims with evidence-based reports.
  • Snopes – Great for checking rumours, social media posts, and hoaxes.
  • Full Fact – UK-based, checks media and political claims with simple explanations.
  • Reuters Fact Check – Confirms or debunks images, quotes, and viral content around the world.

Portuguese Platforms

  • Polígrafo – Checks Portuguese media, political claims, and social content.
  • Observador Fact Check – Trusted fact-checking section of a national newspaper.
  • Lusa Verifica – Fact-checks public claims, launched by Portugal’s state news agency.
  • Global Fact-Check Chatbot – Multi-language tool that searches fact-checks from around the world.

How to Use These Tools

  • Search the main topic or quote from the post you want to check.
  • Look for trustworthy signs: sources, date, and neutral language.
  • Try cross-checking a story on two different sites.

 

You can save this list to your device or copy and share it with someone you care about. These tools are a great way to feel more confident — and help others stay informed too.

Tips for Helping Others

  • Ask: “Shall we double-check that together?”
  • Be kind, not critical
  • Share these tools as a gift, not a correction
