The Summary Quoteboard displays snapshot quote data. When available, Bid and Ask information from the Cboe BZX Exchange is updated as new data is received. Volume is also updated but is the delayed consolidated Volume from the symbol's exchange. Quoteboard data fields include:

The Barchart Technical Opinion widget shows you today's overall Barchart Opinion with general information on how to interpret the short and longer term signals. Unique to Barchart.com, Opinions analyzes a stock or commodity using 13 popular analytics in short-, medium- and long-term periods. Results are interpreted as buy, sell or hold signals, each with numeric ratings and summarized with an overall percentage buy or sell rating. After each calculation the program assigns a Buy, Sell, or Hold value with the study, depending on where the price lies in reference to the common interpretation of the study. For example, a price above its moving average is generally considered an upward trend or a buy.

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).

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.

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.

The Barchart Technical Opinion rating is a 100% Buy with a Strengthening short term outlook on maintaining the current direction.

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.

The Quote Overview page gives you a snapshot view for a specific symbol. Real-time prices are provided by Cboe BZX Exchange on individual U.S. equities quote pages. During market hours, the real-time Cboe BZX price displays and new trade updates are updated on the page (as indicated by a "flash"). Volume always reflects consolidated markets. If the symbol has pre-market or post-market trades, that information will also be reflected along with the last (closing) price from the symbol's exchange. Real-time prices are available during market hours (9:30 AM to 4:00 PM EST).

Note: The Cboe BZX Exchange currently accounts for approximately 11-12% of all U.S. equity trading each day. As a result, the real-time prices displayed may have minor discrepancies when comparing the information with other sites offering real-time data, or with brokerage firms.

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.

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

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.
