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.

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.

transmittance: The ratio of the radiation transmitted through and emerging from a body to the total radiation incident on it. Also equivalent to one minus the absorptance.

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...

Refractionoccurs whenlightpassingfromone medium to another

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.

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.

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.
