A hypothesis is like a super smart guess! It's what you think will happen in an experiment 🔬. We make a hypothesis before we do the experiment. Usually, it's written as an 'If...then...' statement. 'If I water my plant every day, then it will grow taller' is a great example. We'll test our hypothesis by doing the experiment and see if our guess was right! 🎉
