In this lesson, students are going to look at sensors and how they are used in many applications. The lesson is connected to the STEM initiative, and gives students an opening to the world of science and engineering.  Students are going to investigate different sensors that are around them and what these sensors are gathering.  Students are going to draw and design a hygrometer which measures humidity levels, select from everyday items to build their hygrometer, test their machine using a spray bottle to increase humidity, evaluate the effectiveness of their construction and present their findings to the class.

Students will analyze how the role of mass media has changed over time, looking specifically at sexual content. Students will also theorize the impact of desensitization and overexposure to media on American society.

This video features the remarkable discovery Jonathan made in 1998 about Basking sharks, the second largest fish on Earth. While diving with Basking sharks in the frigid waters of the Bay of Fundy, Jonathan saw parasitic lampreys on the backs of the sharks. This had never before been documented, so he returned the next year with a shark biologist and a lamprey biologist to attempt to recover living lampreys from the backs of Basking sharks. They didn't think Jonathan could do it. Wait until you see what happens! Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

In the warm and blue waters off Hawaii, Oceanic White Tip sharks often follow behind pods of Pilot whales. For the longest time, biologists have had no idea what is going on. Are they eating the whales? Are they stealing food from the whales? In this video of an expedition to follow the sharks and observe them, Jonathan finally figured out what is going on, and you won‰ŰŞt believe the disgusting truth! Please see the accompanying study guide for educational objectives and discussion points.

This video features the Thresher shark, which may very well be the strangest looking shark in the world, with a tail almost as long as its body. This shark is very rare, almost never seen by divers...until now. Using advanced diving technology, Jonathan visits a remote reef in the Philippines where Thresher sharks show up every morning to be cleaned by small fish. Please see the accompanying study guide for educational objectives and discussion points.

In this video, filmed thirty miles off the coast of North Carolina, there is a shipwreck on the bottom, 130 feet down. Swarming around the wreck are dozens of Sand Tiger sharks. They look menacing, but they seem to be very docile. What are they all doing there, in one spot? That's what Jonathan wants to find out. Using a variety of filming techniques, Jonathan attempts to discover the secrets of the Sand Tiger shark gatherings at the wrecks, and does the first ever night dive with these shark..talk about scary! Please see the accompanying study guide for educational objectives and discussion points.

In this video from Science City, Shaundra Bryant Daily, an electrical engineer, describes a software program she developed to help girls reflect on their emotions, and how her two passionsí_í_íŹscience and danceí_í_íŹare connected.

Students will learn how to distinguish different video shots, angles, and movements by watching a professionally created movie trailer. Locate a movie trailer of your choice and convert it into a movie file that can be uploaded into a video editing software, such as iMovie. Students will then detach the audio so it is not a distraction while working during class. The next step will be to locate the different camera uses, angles, and movements as listed in the PowerPoint. Once the shots are located, students will split the video and use a freeze frame with on-screen text to key the name of the shot. An example would be "long shot with bird's eye view." Students should locate at least three examples for each of the camera uses, angles, and movements. Once done, the students will export their movie and submit for grading.

Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and electrons slowly creep along a wire. The light turns on when the signal reaches it.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts. Escapements are found in mechanical clocks, such as those driven by a pendulum or a spring. Learners will build the wrapping form of escapement said to be used in a fifteenth-century German clock.

Students apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the engineers and builders of the great pyramids. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action. This lesson guide provides one of many ways to build the spinner and links to other methods.

Is it a tumor? Magnetic Resonance Imaging (MRI) can tell. Your head is full of tiny radio transmitters (the nuclear spins of the hydrogen nuclei of your water molecules). In an MRI unit, these little radios can be made to broadcast their positions, giving a detailed picture of the inside of your head.

The purpose of this resource is to investigate the center pixel of a homogeneous land Cover Site in order to understand that individual land areas are part of a larger land system.

In this classroom/lab activity students investigate how complex machines are made up of simple machines by dissecting four common household appliances.

This is an activity about the electromagnetic spectrum and how the different wavelengths of light are used to capture the most complete picture of objects in space. Learners will view images of our galaxy in multiple wavelengths to compare and analyze what is seen. This activity requires a computer with Internet access, and is Astronomy Activity 3 in a larger resource entitled Space Update.

Small Districts, Big Hurdles: Cybersecurity Support for Small, Rural, and Under-resourced Districts, offers details on how state agencies and other support organizations are empowering their smallest districts to secure their data and networks. From detailing various funding sources to providing insights into statewide and regional partnerships and offering practical examples of cybersecurity training, the document is a must-read for everyone involved in helping districts improve their cybersecurity posture. It is the newest addition to SETDA’s Cybersecurity & Privacy Collection.

In this video segment adapted from NOVA scienceNOW, learn about engineering innovations that could help detect a bridge's structural weaknesses before they become dangerous.

The smart grid of the future is a complex electrical power system. Its study, design, and management requires the integration of knowledge from various disciplines including sustainability, technology and mathematics.

Smart grids show a level of complexity and heterogeneity that often cannot be covered by analytical methods. Therefore, modeling and simulation are of great importance.

In this course, you will apply modeling tools to study and analyze the performance of your self-designed intelligent electrical power grid. By modeling smart grids, you will explore the integration of renewable energy sources into a grid, its dynamics, control and cyber security.
