Imagine you're going on a time-travel adventure to see what happened in science 50, 100, and 150 years ago, like visiting different parts of a big, fun playground!
50 years ago, scientists found out that people can be born with two sets of genes instead of one. This is called genetic disorders, and it helps doctors understand why some kids are born with special needs or talents.
100 years ago, something cool happened: people started flying in the sky like birds! The first airplane flew, showing that humans could conquer the air, just like how you can climb stairs and reach new heights!
150 years ago, scientists discovered that light behaves like both a wave and a particle. It was like finding out your favorite toy can act like two different toys at once, surprising and exciting!
Each of these events is like a stepping stone in the big science journey. Just like how you learn new tricks every day, scientists keep learning and discovering amazing things!
