Is That Website Telling the Truth?

Imagine you search online for a science project and find a page that says in giant letters: "SCIENTISTS PROVE CHOCOLATE MAKES KIDS SMARTER!" Below it is a photo of a happy kid and a big button that says "Buy Our Chocolate Now." Should you believe it? A smart thinker does not just accept it or reject it, they investigate. This lesson gives you three questions detectives use to check whether something online is really true.

What You'll Learn

- How to find out WHO made a website and why that matters - How to spot when someone is trying to sell you something - How to check a fact in more than one place - How to rate a real web page using a checklist you build

Question 1: Who Made This?

Every website was made by someone, and that someone has a reason. A page about tigers made by a zoo or a science museum is trying to teach you. A page made by a company selling tiger toys is trying to sell you toys. Look for an "About" link, an author's name, or the kind of website it is. A site that ends in .gov (government) or .edu (school or university) is usually careful about facts. A site with no author name at all is a yellow flag, slow down and be careful.

Question 2: What Are They Trying to Get Me to Do?

Go back to the chocolate page. Right next to the amazing claim is a "Buy Now" button. That is a big clue. When a page wants your money, it has a reason to stretch the truth. Ask yourself: does this page just want to inform me, or does it want me to buy something, click something, or feel scared or excited? Strong feelings, ALL CAPITAL LETTERS, and lots of exclamation points are tricks used to rush your brain past its careful thinking.

The Two-Source Rule

Never trust a surprising fact from just one website. If it is really true, you should be able to find the same fact on at least one OTHER trustworthy site that is not trying to sell you anything.

Question 3: Can I Check It Somewhere Else?

This is the most powerful step. Open a new tab and search for the same claim on a different, trusted site. If three careful sources agree that chocolate does NOT actually make you smarter, then the chocolate company's page was not telling the whole truth. Real facts show up in lots of trustworthy places. A made-up claim usually only appears where someone benefits from it.

Match each clue on a web page to what a smart thinker should do about it.

Terms

A giant Buy Now button next to the fact

An address ending in .gov or .edu

No author name anywhere

ALL CAPS and lots of exclamation marks

Definitions

Be careful, they may want your money

They are trying to rush your thinking

Slow down, you cannot tell who is talking

Usually a careful, trustworthy source

Drag terms onto their definitions, or click a term then click a definition to match.

🎯

Build a Website Trust Detector

Make a checklist card you can reuse. 1) On an index card, write these three questions: WHO made it? WHAT do they want me to do? CAN I check it elsewhere? 2) With a grown-up or teacher, find one real web page about an animal you like. 3) Answer all three questions about that page in writing. 4) Give the page a trust score from 1 (do not trust) to 5 (very trustworthy) and write one sentence explaining your score. Keep the card to use next time you research online.
