This video introduces students to the "Send That Signal" lesson plan from Science Buddies. Students will use light, sound, and vibrations to communicate to a phone using an app that accesses the built-in sensors on a mobile phone.

To view full directions for this science project, see the "Send That Signal" lesson plan at Science Buddies: https://www.sciencebuddies.org/lesson-plans/send_signal
