Why should learning be hard? Answer - it doesn't need to be. With STEMpump, learn whatever you want, however you want. Just like that. How you learn is just as important as what you learn. So join a camp, and learn with us live. Or if you'd instead go at your own pace, maybe a course is a better fit. We can help if you have to study for the test in the morning or if you want to build an app in an hour. STEMpump is 100% student-led, student-built, and student-run. We're taking the ways we learned and giving everyone access. We designed this app to share our passion for STEAM. But, the fact is, educational resources and content on STEAM topics are hard to come by. Some resources are locked behind paywalls. Others are outdated and haven't been updated in forever. And some are just difficult and confusing. Since the founding of STEMpump in September 2019, we have taught over 120,000+ students worldwide. We believe that every student should always have access to the same resources and opportunities. EXPLORE OUR EXPANSIVE COURSE LIBRARY We divide our courses into six subjects, built upon STEAM: • Science • Technology • Engineering • Art • Math • Other (everything else!) Study up for your AP class or learn some of the most incredible skills, such as Swift, React.js, or even Figma. DISCOVER SOMETHING NEW, LIVE Say hello to STEMpump Camps, a free and live online platform for students to explore STEAM. You can register and watch camps for free! Our camps contain content across the STEAM spectrum. We're always teaching something new. In our camps, you'll learn how to do something specific rather than learn everything. There are new camps every month! No camp is the same, and mistakes are a part of our process. LEARN THE WAY YOU WANT TO Now on STEMpump, you can test your knowledge with our new Quizzes and Projects. With quizzes, test what you've learned with multiple choice and text-based questions! And in projects, you can apply what've you learned in open exercises to solve real-world problems. Tired of reading? Select lessons have videos to make things a bit easier. And soon, unplug and play. Download STEMpump content for offline learning. The app even has a few unique features not available on our website, making it the best option for on-the-go learning. TRACK YOUR LEARNING STEMpump can even keep track of your learning, ensuring you stay on task. Find something you want to check out later? Just add it to your Favorites. Then, you can jump back into it whenever. Widgets can show your recently viewed courses to help you continue learning. You can also share courses, camps, and lessons! --- STEMpump is a 501(c)(30 nonprofit organization. Our mission is to provide the world with free education and give students a platform to create and share. For more information, visit our website: https://www.stempump.org
