Solving Real-World Problems: The internet of things (IoT) is a way for students to collect and analyze real-world data to solve important problems.

Today, almost every electronic device, even tiny ones, can be connected in some way to the internet. For that reason, it's critical to understand how data can move in and out of those devices! IoT lets us remotely control lights in our home, monitor our property and make data-informed decisions about our communities, factories, and businesses.

Students use App Inventor to perform data acquisition, then graph and analyze their results in the app!
