Exploring Nondestructive Evaluation Methods
Read the Fine Print
Educational Use
Rating
0.0 stars

Through this lesson and its series of hands-on mini-activities, students answer the question: How can we investigate and measure the inside of an object or its structure if we cannot take it apart? Unlike the destructive nuclear weapon test (!), nondestructive evaluation (NDE) methods are able to accomplish this. After an introductory slide presentation, small groups rotate through five mini-activity stations: 1) applying Maxwell’s equations, 2) generating currents, 3) creating magnetic fields, 4) solving a system of equations, and 5) understanding why the finite element method (FEM) is important. Through the short experiments, students become familiar with the science and physics being used and make the mathematical connections. They explore components of NDE and see how engineers find unseen flaws and cracks in materials that make aircraft. A pre/post quiz, slide presentation and worksheet are included.

Rating
0.0 stars

Students learn about video motion capture technology, becoming familiar with concepts such as vector components, magnitudes and directions, position, velocity, and acceleration. They use a (free) classroom data collection and processing tool—the ARK Mirror—to visualize and record 3-D motion. The Augmented Reality Kinematics (ARK) Mirror software collects data via a motion detector. Using an Orbbec Astra Pro 3D camera or Microsoft Kinect (see note below), students can visualize and record a robust set of data and interpret them using statistical and graphical methods. This lesson introduces students to just one possible application of the ARK Mirror software—in the context of a high school physics class. Note: The ARK Mirror is ported to operate on an Orbbec platform. It may also be used with a Microsoft Kinect, although that Microsoft hardware has been discontinued. Refer to the Using ARK Mirror and Microsoft Kinect attachment for how to use the ARK MIrror software with Microsoft Kinect.

Educational Use
Rating
0.0 stars

Students are introduced to the growing worldwide environmental problems that stem from plastic waste. What they learn about microplastics and the typical components of the U.S. water treatment process prepares them to conduct three engaging associated activities. During the lesson, students become more aware of the pervasiveness and value of plastic as well as the downstream pollution and health dangers. They learn how plastic materials don’t go away, but become microplastic pollution that accumulates in water resources as well as human and other animal bodies. They examine their own plastic use, focusing on what they discard daily, and think about better ways to produce or package those items to eliminate or reduce their likelihood of ending up as microplastic pollution. A concluding writing assignment reveals their depth of comprehension. The lesson is enhanced by arranging for a local water treatment plant representative to visit the class for Qs and As. In three associated activities, students design/test microplastic particle filtering methods for commercial products, create mini wastewater treatment plant working models that remove waste and reclaim resources from simulated wastewater, and design experiments to identify the impact of microplastics on micro-invertebrates.

A Tale of Friction
Read the Fine Print
Educational Use
Rating
0.0 stars

Roller coasters projects are frequently used in middle and high school physics classes to illustrate the principle of conservation of mechanical energy. Potential energy transforms to kinetic energy and vice versa, with gravity being the driving force during the entire process. Even though friction force is mentioned, it is rarely considered in the velocity calculations along the coasters’ paths. In this high school lesson, the friction force is considered in the process. Using basic calculus and the work-energy theorem for non-conservative forces, the friction along a curved path is quantified, and the cart’s velocity along this path is predicted. This activity and its associated lesson are designed for AP Calculus. Practice problems/answers, a PowerPoint® presentation and student notes are provided.
