What are hypotheses?

A hypothesis is like a guess that you can test to see if it’s true.

Imagine you're playing with your toys and you notice something strange: every time you push your red car, it goes faster than your blue car. You might think, “Maybe the red car is faster because it's lighter.” That thought, your hypothesis, is like a mini plan to figure out what’s really going on.

Now, you can test your guess by trying different things: maybe you take off the red car’s roof or put something heavy on the blue car. If the red car still goes faster, your guess might be right! If not, you try a new hypothesis, like “Maybe the wheels are smoother on the red car.”

It's just like when you're trying to figure out why your cereal is always in the last bowl, you make a guess, then test it with each spoonful. That’s how scientists work too, they use hypotheses every day to understand the world around them!
