The phenomenon that launches this unit is a cell phone call to a student in the class, where the caller on speaker phone asks “How are you hearing me?”. Over the course of the unit, students discover the patterns with waves. Then use that understanding to explain ultrasound medical imagining technology and ultimately how cell phones work. Cell phone communication is operationalized by the engineering challenge of communicating a three letter signal by first coding a spreadsheet to digitize the signal in binary (ASCII), then transmit the digital signal using light and sound (AM and FM), then receive and decode the signal to complete the communication. This project models the sending and receiving of a text message.

The Triple E Framework, developed in 2011 by Professor Liz Kolb at the University of Michigan, School of Education, was created to address the desire for K-12 educators to bridge research on education technologies and teaching practice in the classroom.

This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe in more depth.

Our brains control every movement we make. Most of us take for granted our ability to pick up a cup or change the television station. However, for people who have lost a limb or become paralyzed, the inability to do these things means a loss of freedom and independence. This video segment from Greater Boston describes how neuroscientists and bioengineers have teamed up to create a system that allows people who have lost motor functions to control electronic devices through their thoughts alone. Grades 6-12

Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars.
Recommended for: Grades 3-12

In this video segment adapted from ZOOM, cast members make their own hovercraft and demonstrate how the air leaking out of a balloon can make a plastic plate hover above a table.

This is a science unit plan for 1st grade about different biomes/habitats and what the characteristics and adaptations are of the animals that live there. It is a technology based unit using resources like Nearpod, Adobe Spark, LMS, etc.Title Image: MathKnight -at- TAU, Nov. 11, 2015, Animals of Israel, CC-BY-SA-3.0

This video segment adapted from Building Big illustrates the strength of the arch in bridge design and construction.

Remember your multiplication tables? ... me neither. Brush up on your multiplication, division, and factoring skills with this exciting game. No calculators allowed! The students will be given mutiplication and division problems which they must answer. They also have the option of being given a number then stating the factors of how that number was attained using either multiplication or division.

Explore some of the wonders of modern engineering in this video from the Sciencenter in Ithaca, New York. Hear a diverse selection of engineers explain how things work.

In this video segment produced for Teachers' Domain, Andres Berrio, an associate scientist at Biogen Idec, discusses what he has done to succeed in the biotechnology field.

The engineering design process involves many steps. Not only must an engineer be able to devise a solution to a problem, he or she must also be ready to test and evaluate that solution to reach the best result. To successfully complete the design process, an engineer must be able to identify design flaws and learn from his or her mistakes. In this video segment adapted from ZOOM, learn about the design process as cast members create automatic door openers that enable them to open their bedroom doors while lying on their beds. For grades 3-8.

This professional development article describes approaches to using social media in harnessing the power of Web 2.0 technologies to reinforce the connection between multimedia literacy and powerful content-area learning in grades K-5. The emphasis is on collaboration with the school librarian. The article appears in the free online magazine Beyond Weather and the Water Cycle, which is structured around the seven essential principles of the climate sciences.

This lesson is a classroom activity where students learn to use their balance knowledge to create a beautiful mobile.

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction. Learners use the bicycle wheel like a giant gyroscope to explore angular momentum and torque. Learners can participate in the assembly of the Bicycle Wheel Gyro or use a preassembled unit to explore these concepts and go for an unexpected spin!

In this video segment adapted from NOVA scienceNOW, scientists discuss their attempts to grow human body parts in a jar.

This ZOOM video segment shows how to create a self-contained environment and explores evaporation, condensation, and precipitation.
