Students learn how 3D printing, also known as additive manufacturing, is revolutionizing the manufacturing process. First, students learn what considerations to make in the engineering design process to print an object with quality and to scale. Students learn the basic principles of how a computer-aided design (CAD) model is converted to a series of data points then turned into a program that operates the 3D printer. The activity takes students through a step-by-step process on how a computer can control a manufacturing process through defined data points. Within this activity, students also learn how to program using basic G-code to create a wireframe 3D shapes that can be read by a 3D printer or computer numerical control (CNC) machine.
In the first of two sequential lessons, students create mobile apps that collect data from an Android device's accelerometer and then store that data to a database. This lesson provides practice with MIT's App Inventor software and culminates with students writing their own apps for measuring acceleration. In the second lesson, students are given an app for an Android device, which measures acceleration. They investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Then they use the data to create velocity vs. time graphs and approximate the maximum velocity of the device.

Learn how computers can be programmed to beat the greatest human chess masters. Computers can use their understanding of the rules of chess to plan many more moves ahead than humans can. But when computers bring that kind of understanding to other situations they lack the intelligence needed to successfully master those tasks.
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.
How do drones automatically balance themselves when you let go of the controls? Find out in this project as you build and program an experimental setup to make a drone automatically control its tilt angle about a single axis.
How do we act when we are on the Internet? Here are some good manners for when we are on the Internet. Use good words, not rude or bad words. Be patient with others. Sometimes others are beginners and are just learning how to use the Internet. [1:57]
No matter where you go online, being a good digital citizen can make your experience smoother and safer. Thankfully, you can become a better digital citizen by following the simple steps outlined in this tutorial. [2:39]
Students learn how engineers gather data and model motion using vectors. They learn about using motion-tracking tools to observe, record, and analyze vectors associated with the motion of their own bodies. They do this qualitatively and quantitatively by analyzing several examples of their own body motion. As a final presentation, student teams act as engineering consultants and propose the use of (free) ARK Mirror technology to help sports teams evaluate body mechanics. A pre/post quiz is provided.
In this video, Paul Andersen explains how society influences the natural world through increasing science, engineering, and technology. As the world population increases, it will require more natural resources and it will impact the global conditions. Society can control some of these changes through regulations. A K-12 teaching progression is also included. [5:22]
Students learn about the similarities between the human brain and its engineering counterpart, the computer. Since students work with computers routinely, this comparison strengthens their understanding of both how the brain works and how it parallels that of a computer. Students are also introduced to the "stimulus-sensor-coordinator-effector-response" framework for understanding human and robot actions.
This lesson, based on the 11-minute animated story "Brand New Flag" from the PBS KIDS series MOLLY OF DENALI, helps children use captions to access and convey meaning in informational texts. After Molly learns about the history of Alaska's state flag, she holds a contest to design a flag for the Trading Post. Entries come flooding in with captions to explain each design. Molly must decide which one truly captures the spirit of the Trading Post. After watching, students create informational text with captions in the context of a current unit that they are studying.
Contains plans for five lessons that ask students to create PowerPoint presentations about shared experiences like field trips or other activities. Students take pictures of what happen, and then explain the sequence of events in words and images. In addition to objectives and standards, this instructional plan contains links to sites used in the lessons as well as assessment and reflection activities.
Students create projects that introduce them to Arduino—a small device that can be easily programmed to control and monitor a variety of external devices like LEDs and sensors. First they learn a few simple programming structures and commands to blink LEDs. Then they are given three challenges—to modify an LED blinking rate until it cannot be seen, to replicate a heartbeat pattern and to send Morse code messages. This activity prepares students to create more involved multiple-LED patterns in the Part 2 companion activity.
