Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.

Consistent housing is a continual issue for our community, evidence of this is readily observable in the neighborhoods surrounding our classrooms. Over the course of 15 classroom hours, students will be exploring how they can insulate structures to protect from extreme hot and extreme cold using recycled and/or repurposed materials.

Students will make observations and collect data related to temperature. Student findings will be communicated through science journals, student generated models (charts, 3D structures, drawings, etc.).

Students learn and use the properties of light to solve the following challenge: "A mummified troll was discovered this summer at our school and it has generated lots of interest worldwide. The principal asked us, the technology classes, to design a security system that alerts the police if someone tries to pilfer our prized possession. How can we construct a system that allows visitors to view our artifact during the day, but invisibly protects it at night in a cost-effective way?"

The learning of linear functions is pervasive in most algebra classrooms. Linear functions are vital in laying the foundation for understanding the concept of modeling. This unit gives students the opportunity to make use of linear models in order to make predictions based on real-world data, and see how engineers address incredible and important design challenges through the use of linear modeling. Student groups act as engineering teams by conducting experiments to collect data and model the relationship between the wall thickness of the latex tubes and their corresponding strength under pressure (to the point of explosion). Students learn to graph variables with linear relationships and use collected data from their designed experiment to make important decisions regarding the feasibility of hydraulic systems in hybrid vehicles and the necessary tube size to make it viable.

This Lifespan Development textbook is an up-to-date summary of human development from conception to the end of childhood. The material chosen has relevance to health sciences (nursing and pre-professional), psychology, education, human services/social work, and clinical mental health counseling students. The biopsychology of the developing person is emphasized over the history of psychological theories. The data focuses on American children and society; every effort was made to counter the bias that is implicit in many textbooks on this topic.

¡Listos! is a series of units for Heritage Spanish learners in grades 6-12. Three lessons aligned to the K12 Texas Essential Knowledge and Skills (TEKS) form four thematic clusters. Relevant scenarios related to personal life, college tasks, career readiness and civic participation frame each lesson and increase student engagement by making learning authentic and relevant to real issues that students face. Each lesson identifies an intermediate or advanced proficiency target that supports language acquisition in the interpersonal, interpretive and presentational modes. The project also provides teachers with a replicable approach to lesson design for adapting or creating their own materials.

The Lost in the Amazon curricular unit is a series of minds-on and hands-on engineering activities based on an adventure scenario set in the Amazon rainforest in Brazil. Students imagine themselves to be a team of EnviroTech engineers returning to the U.S. from a conference in Brasilia, Brazil. When their plane crashes deep in the Amazon forest, they work in groups to overcome various obstacles in their quest to survive and reach the nearest city as quickly and safely as possible. Motivated by this adventurous theme, students discover, learn and apply the following: 1) classification of plants and insects; 2) general categorizing skills; 3) process skills: problem solving and critical thinking; 4) scientific testing and experimentation; 5) materials properties.

Students are given an engineering challenge: A nearby hospital has just installed a new magnetic resonance imaging facility that has the capacity to make 3D images of the brain and other body parts by exposing patients to a strong magnetic field. The hospital wishes for its entire staff to have a clear understanding of the risks involved in working near a strong magnetic field and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks, the physics behind those risks, and the safety precautions to be taken by all staff members. This 10-lesson/4-activity unit was designed to provide hands-on activities to teach end-of-year electricity and magnetism topics to a first-year accelerated or AP physics class. Students learn about and then apply the following science concepts to solve the challenge: magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's law and Faraday's law. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.

Students will breed fruit flies through several generations and record their data using mathematical models in order to demonstrate the inheritance of trait variations.

Through two lessons and four activities, students learn about nanotechnology, its extreme smallness, and its vast and growing applications in our world. Embedded within the unit is a broader introduction to the field of material science and engineering and its vital role in nanotechnology advancement. Engaging mini-lab activities on ferrofluids, quantum dots and gold nanoparticles introduce students to specific fields within nanoscience and help them understand key concepts as the basis for thinking about engineering and everyday applications that use next-generation technology nanotechnology.

Through this unit, students act as engineers who are given the challenge to design laparoscopic surgical tools. After learning about human anatomy and physiology of the abdominopelvic cavity, especially as it applies to laparoscopic surgery, students learn about the mechanics of elastic solids, which is the most basic level of material behavior. Then, they explore the world of fluids and learn how fluids react to forces. Next, they combine their understanding of the mechanics of solids and fluids to understand viscoelastic materials, such as those found in the human body. Finally, they learn about tissue mechanics, including how collagen, elastin and proteoglycans give body tissues their unique characteristics. In the culminating hands-on activity, student teams design their own prototypes of laparoscopic surgical robots remotely controlled, camera-toting devices that must fit through small incisions, inspect organs and tissue for disease, obtain biopsies, and monitor via ongoing wireless image-taking. They use a (homemade) synthetic abdominal cavity simulator to test and iterate the prototype devices.

Students learn about the human body's system components, specifically its sensory systems, nervous system and brain, while comparing them to robot system components, such as sensors and computers. The unit's life sciences-to-engineering comparison is accomplished through three lessons and five activities. The important framework of "stimulus-sensor-coordinator-effector-response" is introduced to show how it improves our understanding the cause-effect relationships of both systems. This framework reinforces the theme of the human body as a system from the perspective of an engineer. This unit is the second of a series, intended to follow the Humans Are Like Robots unit.

Amidst tensions over European political and territorial boundaries, the assassination of Archduke Franz Ferdinand by a Serbian terrorist in 1914 derailed peace in the western world by sparking World War I—one of the highest-casualty conflicts in modern times. While European nations quickly engaged, the United States immediately declared neutrality. By 1917, however, remaining neutral was no longer an option. The Great War would bring the United States out of isolationism and onto the world stage. It would also change life on the American home front forever. A centralized government took control of American life in an unprecedented fashion by instating a mandatory military draft, controlling industries, initiating food and ration restrictions, and launching elaborate campaigns to encourage patriotism. One of the most important, if temporary, changes brought by the war at home came from the stifled flow of labor, as men were pulled away by the draft and immigration slowed. The need for American labor provided second-class citizens, such as women and African Americans, a brief opportunity for better jobs. This glimpse would help foment in them a desire for more and equal opportunities after they were pulled away once more at war’s end. This exhibition was created as part of the DPLA’s Public Library Partnerships Project by collaborators from Digital Commonwealth. Exhibition organizer: Anna Fahey-Flynn.

Through a series of four lessons, students are introduced to many factors that affect the power output of photovoltaic (PV) solar panels. Factors such as the angle of the sun, panel temperature, specific circuit characteristics, and reflected radiation determine the efficiency of solar panels. These four lessons are paired with hands-on activities in which students design, build and test small photovoltaic systems. Students collect their own data, and examine different variables to determine their effects on the efficiency of PV panels to generate electrical power.

From drinking fountains at playgrounds, water systems in homes, and working bathrooms at schools to hydraulic bridges and levee systems, fluid mechanics are an essential part of daily life. Fluid mechanics, the study of how forces are applied to fluids, is outlined in this unit as a sequence of two lessons and three corresponding activities. The first lesson provides a basic introduction to Pascal's law, Archimedes' principle and Bernoulli's principle and presents fundamental definitions, equations and problems to solve with students, as well as engineering applications. The second lesson provides a basic introduction to above-ground storage tanks, their pervasive use in the Houston Ship Channel, and different types of storage tank failure in major storms and hurricanes. The unit concludes with students applying what they have learned to determine the stability of individual above-ground storage tanks given specific storm conditions so they can analyze their stability in changing storm conditions, followed by a project to design their own storage tanks to address the issues of uplift, displacement and buckling in storm conditions.

On December 7, 1941, Imperial Japan attacked a US naval base at Pearl Harbor, Hawaii. Pre-existing racial tensions and “yellow peril” hysteria magnified as the American public grew increasingly suspicious of Japanese Americans and uncertain of their loyalty. They were regarded as potential spies and anti-Japanese propaganda quickly spread. Then, on February 19, 1942, President Franklin Delano Roosevelt issued Executive Order 9066. 120,000 people of Japanese ancestry (two-thirds of whom were US citizens) were forced to evacuate from their homes and report to assembly centers. From there, they were moved to one of ten internment camps, or War Relocation Centers, located in remote areas of seven states—California, Arizona, Colorado, Wyoming, Idaho, Utah, and Arkansas.For the next three years, Japanese Americans acclimated to life behind barbed wire and under armed guard. Uprooted from their lives, they found themselves in strange and uncomfortable environments. They had to adapt to their new situation by adjusting to new living conditions, attending new schools, and finding inventive ways to pass the time. They attempted to maintain a sense of normalcy by attending religious meetings and by finding employment.This exhibition tells stories of everyday lives in Japanese Internment camps during World War II. It was created as part of the DPLA’s Digital Curation Program by the following students as part of Dr. Joan E. Beaudoin's course "Metadata in Theory and Practice" in the School of Library and Information Science at Wayne State University: Stephanie Chapman, Jessica Keener, Nicole Sobota, and Courtney Whitmore.

After World War II, there was non-violent, political hostility between the United States and the Soviet Union (USSR), which became known as the Cold War. During this contentious time, both nations created rockets for long-range military weaponry. The Cold War catalyzed the expansion of rocket technology and each country’s desire to conquer outer space. Not only did America want to explore one of the last frontiers, it also wanted to claim technological dominance over the USSR and ensure America’s title of superiority in a time of unease and tension. In 1955, the US and the USSR each announced plans to launch a satellite into orbit. Who would be the first to succeed? On October 4, 1957, the USSR launched Sputnik I into orbit, taking the lead in the Space Race. Only four months later, the US successfully launched its own satellite, the Explorer I, into space. In the wake of these first successful orbital space flights, President Dwight D. Eisenhower recommended to the US Congress that a civilian agency should be established to direct non-military space activities. Thus, the National Aeronautics and Space Administration (NASA) was born and the Space Race was underway. Throughout the 1960s and 1970s, the American space program and its new classes of astronauts achieved breakthroughs in science and space exploration—even sending a man to the Moon. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students in Professor Helene Williams's capstone course at the Information School at the University of Washington: Danielle Rios, Dianne Bohach, Jennifer Lam, and Bobbi deMontigny.

Since before the creation of the first National Parks and Wilderness areas, the Mountain West region has provided ample recreational opportunities in its wide open spaces and rocky terrains. The mountains, deserts, and plains have given visitors the chance to commune with nature and participate in a plethora of outdoor sports and activities. Utah, in particular, but the rest of the Mountain West states (Colorado, Montana, Wyoming, and Idaho) generally, has unique natural settings for many recreational activities that continue to be enjoyed by tourists from across the world. The impact of tourism on the economy and development of the region has been largely positive. However, tourism also increases the human footprint in natural areas, landmarks, and historic sites. This exhibition describes the benefits to the region and its visitors, as well as some of the impacts that tourism has on the natural environment and other economic activities. This exhibition was created as part of the DPLA’s Public Library Partnerships Project by collaborators from Mountain West Digital Library. Exhibition organizer: Della Yeager.

In partnership with teachers, the Louisiana Department of Education arranged OpenSciEd (grade 6-8 science) content in a manner that stays true to the vision of the materials and provides clear guidance on how to use them in a fully remote environment. The modified materials assume that teachers will have synchronous virtual meetings with students in addition to home learning.
The site also provides a variety of resources with options for students who do not have internet access.
