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 this lesson, students learn about sound. Girls and boys are introduced to the concept of frequency and how it applies to musical sounds.

To further their understanding of sound energy, students identify the different pitches and frequencies created by a vibrating ruler and a straw kazoo. They create high- and low-pitch sound waves.

Music and sound are two different concepts that share much in common. Determining the difference between the two can sometimes be difficult due to the subjective nature of deciding what is or is not music. The goal of this activity is to take something constructed by students, that would be normally classified as just sound and have the class work together to make what can be perceived to be music. Students construct basic stringed instruments made of shoeboxes and rubber bands. This activity aims to increase student understanding of what distinguishes music from sound.

Students learn about ultrasound and how it can be used to determine the shapes and contours of unseen objects. Using a one-dimensional ultrasound imaging device (either prepared by the teacher or put together by the students) that incorporates a LEGO(TM) MINDSTORMS(TM) NXT intelligent brick and ultrasonic sensor, they measure and plot the shape of an unknown object covered by a box. Looking at the plotted data, they make inferences about the shape of the object and guess what it is. Students also learn how engineers use high-frequency waves in the design of medical imaging devices, the analysis of materials and oceanographic exploration. Pre/post quizzes, a worksheet and a LEGO rbt program are provided.

This instructional video shows educators how to set up a wave machine using wooden kabob sticks, jelly candies, and duct tape. The video also demonstrates how the wave machine can then be used to illustrate various wave properties. Background content on waves and wave energy is also provided.
