Worksheet & Discussion: As students go through the stations, have them complete the worksheet chart with their predictions and results. In a class discussion, have students share and compare their results and conclusions. Results will vary, depending on the exact materials and light sources used, but in general, expect:

Refractioncauses the bottom of a swimming pool to appear

refraction: The change of direction of a ray of light, heat or sound in passing from one medium into another in which its wave velocity is different.

Students learn about the science and math that explain light behavior, which engineers have exploited to create sunglasses. They examine tinted and polarized lenses, learn about light polarization, transmission, reflection, intensity, attenuation, and how different mediums reduce the intensities of ...

In designing laser-based security systems, engineers consider the implications of the penetrating properties of electromagnetic radiation. The concepts of wave absorption and transmission are fundamental in the design of laser based security systems, and have additional applications in biomedical engineering. In x-ray imaging, various tissue types result in a range of transmittances that can be recorded to depict bones on x-ray film. Engineers must also be aware of safety concerns; even low doses of high-energy radiation can be dangerous, especially in the case of gamma radiation. For cancer radiation treatments, control of high-energy radiation can be beneficial, but must be carefully managed. Students consider the potential real-world uses of various types of radiation in questions 2 and 5-9 of the post-activity assessment handout.

Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.

Today's activity brings a little fun and excitement to the concepts we have recently learned. The purpose of today's hands-on exploration is to reinforce your understanding of how different materials respond to a beam of light. We will explore light absorption, transmission, reflection and refraction. To explore refraction, you will create your own rainbow in the classroom. For the activity, you will spend 15 minutes at each of four stations set up throughout the classroom, answering questions and recording your predictions and observations on a worksheet.

Concluding Handout: After the activity, have students return to their desks and individually complete the What have you learned today? Handout. This assessment contains both content questions and application questions in which students consider applications to designing a security system.

All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org).

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials. (Grades 6 - 8)

Through two classroom demos, students are introduced to the basic properties of lasers through various mediums. Students will gain an understanding of how light can be absorbed and transmitted by different mediums.

This activity provides students with a hands-on means of exploring the light properties of reflection, absorption, transmission and refraction.

Students apply everything they have learned about light properties and laser technologies to designing, constructing, defining design limitations and presenting laser-based security systems that protect the school's mummified troll. In the associated activity, students "test their mettle" by constru...

With an understanding of the properties explored in this activity and an understanding of lasers gained in a future lesson and activity, you will be able to design your invisible laser security system to protect our mummified troll.

Students learn the basic properties of light — the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic spectrum and then provides more in-depth information on visible li...

In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

Units serve as guides to a particular content or subject area. Nested under units are lessons (in purple) and hands-on activities (in blue).
