Science Buddies and Google's Science Journal App

Works with Google's Science Journal app!

Skip collecting a box full of meters, sensors, and measurement tools and, instead, try Google's Science Journal. The free app, available for Android and iOS, transforms smartphones and other mobile devices into a suite of tools for hands-on science, technology, engineering, and math (STEM). Using sensors already on smartphones and mobile devices, the app allows students to collect, visualize, and analyze data in real-time. Ready to give it a try? Our collection of tutorials, classroom-ready lesson plans, and student project ideas will help you get started. Additional activities are available on Google's website.
