The Electromagnetic Spectrum (Developed by SEPUP)
kit #209S
In this multi-day, three-part activity:
• students begin by sharing their current understanding of light and then observing how visible light can be separated into different colors.
• In Part B they conduct an investigation to further explore the visible spectrum that uses unique Lab-Aids© equipment to collect evidence about the amount of energy carried by different colors of visible light.
• The follow-up reading introduces students to the classic experiments that established the existence of infrared and ultraviolet radiation.
• Students learn about the electromagnetic spectrum, applications of infrared energy, and ways that humans have used electromagnetic energy to extend their sensory capabilities.
Accommodates unlimited classes each with 8 groups of 4 students.

- When light shines on an object, it is transmitted through the object depending on the object’s material and the frequency (color) of the light.
- A wave model of light is useful for explaining brightness and color.
- Because light can travel through space, it cannot be a matter wave, like sound or water waves.
- The Sun’s energy arrives as light with a range of wavelengths, consisting of visible light, infrared, and ultraviolet radiation.
- Technology influences society through its products and processes.
- Students develop conclusions based on evidence and reasoning and evaluate and synthesize information from text.
