Ninja Walk with Science Journal

Can you move as smoothly and silently as a Ninja? In this experiment, participants will use their stealthy Ninja skills to move through a noisy obstacle course while wearing a smartphone. They must figure out how to navigate around obstacles with the sound sensor and accelerometers detecting as little motion and sound as possible.

Zipline with Science Journal

What’s it like to be an amusement park engineer? In this design challenge, participants are tasked with creating a fun zipline experience. Their job is to create a model version of the transport vehicle for a zipline. However, like an engineer, participants must keep in mind that their experience can be fast, but it still needs to be stable, safe and enjoyable. Using Science Journal, an app that can use the sensors in everyday smartphones, participants can find out if their zipline ride can stand the test of amusement park guests.

Toy Top with Science Journal

You’ve played with fidget spinners and spinning tops, but have you ever designed them? In this design challenge, participants will develop and test their very own spinning toy! Toy designers and engineers get to play with their toys, but they also need a scientific way to figure out how to make it most fun. Use everyday materials to build a spinning toy, then test it using the accelerometer sensors found in smartphones!

Using Science Journal

Science Journal is a free app designed by Making & Science, an initiative by Google. It allows you to gather data about the world around you by harnessing the sensors in your smartphone. The Tech Museum of Innovation uses Science Journal to hone our ninja skills, explore the sounds around us, test our reflexes and much more.  Watch this video, and then check out the other Data Science activities that use Science Journal: Toy Top, Ninja Walk, and Zipline Descent.
