Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual components of light. After finding the desired angles, students use what they have learned to design their own spectrograph enclosure.

Students are introduced to different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors.

This activity is designed for students working in small groups to investigate light and some of its properties. Through observation and manipulating equipment students will conclude light travels in a straight line. They will be asked to show through drawings and written description what happened to the path of light when it comes in contact with an object. Questions will be generated for further investigation to reinforce their ideas. Groups will be asked to present their findings. The vocabulary words to be discovered are reflect, absorb, and redirect.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a magnifying glass works, students see how the orientation of an image changes with the distance of the lens from its focal point. They also discover how a prism works by refracting light and making rainbows. And, students investigate the polar nature of light using sunglasses and polarized light film.

This resource is from Tools4NCTeachers.  In this lesson, students explore 3D shapes, such as rectangular prisms and cubes. The students will identify the attributes for each 3D shape and build shapes using sticks, marshmallows, and other materials.  Pictures of sample student work and printable recording sheets are provided within this lesson.

This resource is from Tools4NCTeachers.In this lesson, students are given boxes to cut apart.  As they decompose the boxes, students notice the 2-dimensional shapes used to construct their 3-dimensional boxes.  A printable student recording sheet is provided within this lesson.Remix to include pictures of student work samples. 

Students use authentic spectral data from the Cassini mission of Saturn and Saturn's moon, Titan, gathered by instrumentation developed by engineers. Taking these unknown data, and comparing it with known data, students determine the chemical composition of Saturn's rings and Titan's atmosphere.
