Students will demonstrate knowledge of visible light interactions with different materials and through different mediums (air, solids, and water). Students will use Sphero Bolt to create a flashlight. The goal is to create the brightest light from the LED lights on the Sphero BOLT. Students will need to understand how light interacts with different substances to successfully create the brightest flashlight. They will also test their lights in water to see how waves change direction and speed in different mediums.  The Light intensity will be measured using the function in google science journal.

In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine flashlights on a number of preselected objects. To understand refraction, students create indoor rainbows. An understanding of the fundamental properties of light is essential to designing an invisible laser security system.
