Science is scary- REALLY scary. But of all the subject areas we practice in school, science should be the least scary for students. Where else do they openly get to make a guess or prediction, try it out, learn from their mistakes, and then try again? Simple activities such as learning to focus a microscope give students such a window into their own capabilities. By learning to focus a microscope, by actually touching it, not being lectured about, students get the pure joy of seeing into a whole new world- literally! And that's exactly what STEM does for students.
If we, as teachers, don't allow students to try and try again, they'll never have their "ah-ha" moment with science. If we always tell them all the steps to build a successful rocket, they'll never feel pride or true joy in seeing their bottle rocket shoot above the school blacktop. Too often we want to give students the answers- honestly, it's easier- but to cultivate a love of STEM we have to give students the chance to try and fail. We can't just teach them about inventors scientists like Edison and the Wright brothers, we have to make them into those innovators and scientists. No greater subject allows for this process than STEM.
