Start exploring the light sensor in the Arduino Science Journal app, here you will learn what light is measured in and understand what luminance means.

We will compare sunglasses with eclipse glasses, use multiple pairs of sunglasses, and other transparent materials.

Let's create our Sun-illuminated Earth! Let's measure how illumination level changes as latitude changes and discover more about seasons

Translates shadows into the best pop-music hit! We will build our own fully-costumized musical instrument.

This is a simple experiment for measuring the concentration of your favorite drinks.

CAN YOU HEAR ME? Well, the app certainly can! Measure the world in decibels and see the app react to the sounds around you.

Go out on an expedition! See if the app can pick up on the same things you hear. Perhaps there are secrets lurking behind that tree?

Your heart rate changes depending on what you are doing. Investigate how different physical activities affect your heart rate.

Can you observe the Doppler Effect? Yes you can! Measure the changing in decimals as you move around the source of the sound.

Can you track the mystery sound? Use your super sleuth sound skills to see if you can match a sound maker with its graph in this data-matching activity.
