Here is a challenge for your students: you need to send a number to someone on the other side of the classroom. The twist? You are not allowed to talk, write the number down, or use gestures or sign language! How would you do it? In this project, your students will explore different means of transmitting information by sending a message to a phone that can graph light, sound, and vibrations using Google's Science Journal app. They will learn about different sensors and interpreting graphs, and use the data they gather to collaborate and determine how best to transmit the message.
