Lab4U is democratizing science education by turning smartphones into a lab in every student’s pocket and making it easier for educators to plan and teach rigorous, inspiring science classes based on scientific inquiry and exploration. Students can learn science through experimentation and play without the need to access expensive lab equipments.Traditional lab equipment is expensive, inaccessible and hard to use. We’re making digital tools that allow students to use smartphone sensors as lab equipment to learn through experimentation and play. Our mobile applications, Lab4Physics (live on App Store and Google Play) allow students to run pre-designed experiments and collect and analyze data in real time on their own smartphones or tablets. We pair our mobile technology with engaging science content and professional development for science educators to promote learning through experimentation and inquiry. Today, our products have been used by more than 150,000 around the world.
