This art history video discussion looks at "The Seated Scribe"‚ c. 2620-2500 B.C.E., c. 4th Dynasty, Old Kingdom, painted limestone with rock crystal, magnesite, and copper/arsenic inlay for the eyes and wood for the nipples, found in Saqqara (Musee du Louvre, Paris).

In this lesson, students learn about major landforms (e.g., mountains, rivers, plains, valleys, canyons and plateaus) and how they occur on the Earth's surface. They learn about the civil and geotechnical engineering applications of geology and landforms, including the design of transportation systems, mining, mapping and measuring natural hazards.

In this task students use ratio and rate reasoning to solve the real-world problem of placing a security camara in a shop.

Students apply everything they have learned about light properties and laser technologies to designing, constructing and presenting laser-based security systems that protect the school's mummified troll. In the associated activity, students "test their mettle" by constructing their security system using a PVC pipe frame, lasers and mirrors. In the lesson, students "go public" by creating informational presentations that explain their systems, and serve as embedded assessment, testing each student's understanding of light properties.

Survey of the important aspects of modern sediments and ancient sedimentary rocks. Emphasis is on fundamental materials, features, and processes. Textures of siliciclastic sediments and sedimentary rocks: particle size, particle shape, and particle packing. Mechanics of sediment transport. Survey of siliciclastic sedimentary rocks: sandstones, conglomerates, and shales. Carbonate sediments and sedimentary rocks; cherts; evaporites. Siliciclastic and carbonate diagenesis. Paleontology, with special reference to fossils in sedimentary rocks. Modern and ancient depositional environments. Stratigraphy. Sedimentary basins. Fossil fuels: coal, petroleum.

Students learn how to create two-dimensional representations of three-dimensional objects by utilizing orthographic projection techniques. They build shapes using cube blocks and then draw orthographic and isometric views of those shapes—which are the side views, such as top, front, right—with no depth indicated. Then working in pairs, one blindfolded partner describes a shape by feel alone as the other partner draws what is described. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills.

The purpose of this task is to identify the structure in the two algebraic expressions by interpreting them in terms of a geometric context. Students will have likely seen this type of process before, so the principal source of challenge in this task is to encourage a multitude and variety of approaches, both in terms of the geometric argument and in terms of the algebraic manipulation.

Students examine the existence of sound by listening to and seeing sound waves while conducting a set of simple activities as a class or in pairs at stations. Students describe sound in terms of its pitch, volume and frequency. They use this knowledge to discuss how engineers study sound waves to help people who cannot hear or talk.

The purpose of this task is to help students see that 4_(9+2) is four times as big as (9+2). Though this task may seem very simple, it provides students and teachers with a very useful visual for interpreting an expression without evaluating it.

Students participate in a variety of activities modeling different disabilities. They gain a better understanding of physical limitations while performing tasks at workstations without the use of their thumbs (taped down), impaired vision (various glasses) and impaired mobility (using crutches and wheelchairs). After discussing their experiences, they work in teams to create or improve on an adaptive device. Like biomedical engineers, students are challenged to design with the purpose of helping make a particular task easier for another person.

Through this concluding lesson and its associated activity, students experience one valuable and often overlooked skill of successful scientists and engineers communicating your work and ideas. They explore the importance of scientific communication, including the basic, essential elements of communicating new information to the public and pitfalls to avoid. In the associated activity, student groups create posters depicting their solutions to the unit's challenge question accurate, efficient methods for detecting cancer-causing genes using optical biosensors which includes providing a specific example with relevant equations. Students are also individually assessed on their understanding of refraction via a short quiz. This lesson and its associated activity conclude the unit and serve as the culminating Go Public phase of the Legacy Cycle, providing unit review and summative assessment.

Our school, Kelly Middle School, is one of the oldest middle school buildings in 4J (primary construction was completed in 1945). Each year we practice earthquake drills. Why? Why should we be concerned about earthquakes? Where might an earthquake occur in the northwest area? Might it be minor or violent? How might this be measured? Is an earthquake a singular event, or a series of events? What increases or decreases an earthquake hazard? Do we have any early-warning systems? Is the school earthquake drill correct? Considering these questions students need to develop an understanding of how to prepare for, and react to an earthquake event. When students are comfortably informed, who should they report to?

Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.

Students learn about seismology by using a sample seismograph constructed out of common classroom materials. The seismograph creates a seismogram based on vibrations caused by moving a ruler. The students work in groups to represent an engineering firm that must analyze the seismograph for how it works and how to read the seismogram it creates.

General study of modern architecture as a response to important technological, cultural, environmental, aesthetic, and theoretical challenges after the European Enlightenment. Focus on the theoretical, historiographic, and design approaches to architectural problems encountered in the age of industrial and post-industrial expansion across the globe, with specific attention to the dominance of European modernism in setting the agenda for the discourse of a global modernity at large. Explores modern architectural history through thematic exposition rather than as simple chronological succession of ideas.

This short video and interactive assessment activity is designed to teach fourth graders about selecting the incorrect statement.

Students learn that engineers develop different polymers to serve various functions and are introduced to selectively permeable membranes. In a warm-up activity, they construct models of selectively permeable membranes using common household materials, and are reminded about simple diffusion and passive transport. In the main activity, student pairs test and compare the selective permeability of everyday polymer materials engineered for food storage (including plastic grocery bags, zipper sandwich bags, and plastic wrap) with various in-solution molecules (iodine, corn starch, food coloring, marker dye), assess how the polymer’s permeability relates to its function/purpose, and compare that to the permeability of dialysis tubing (which simulates a cell membrane).
