When we look at the night sky, we see stars and the nearby planets of our own solar system. Many of those stars are actually distant galaxies and glowing clouds of dust and gases called nebulae. The universe is an immense space with distances measured in light years. The more we learn about the universe beyond our solar system, the more we realize we do not know. Students are introduced to the basic known facts about the universe, and how engineers help us explore the many mysteries of space.

In this lesson students are introduced to another high-level protocol of the Internet, [v HTTP]. The lesson begins with a review of the layers of the Internet covered thus far, before transitioning to a video covering high-level protocols of the Internet, most notably HTTP. Students will investigate HTTP traffic generated within their own browser by accessing the browser’s developer tools and visiting a variety of websites. A handout summarizing the structure of HTTP is provided to help students understand the components of the HTTP requests and responses they will observe. The lesson concludes with students sharing their findings with their classmates and a reflection on how the layers of the Internet make use of abstraction.

Christopher Columbus is one of the most controversial figures in history.  By some, he is viewed as a grand explorer who opened up new areas for European conquest and profit.  But by others, he is viewed as a butcher, who brought disease, and who's actions began the destruction of an entire continent's population.  This lesson will show you two different views of Columbus so that you can draw your own conclusions about whether we should celebrate Columbus or not.

In this class we will focus on the connections between urban exploration and reading, attending to such shared concerns as pacing, legibility, transgression, attention and distraction, tracing and retracing, and memory. This idea of re-reading cities will be both a theme centering our discussions and a guiding principle of the course design, as we continuously loop back, returning to haunt texts we left behind earlier in the semester.

"I never knew a whole family to live together, till all were grown up, in my life," recalls Lewis Clarke of his twenty-five years enslaved in Kentucky.1 Families were separated due to sale, escape, early death from poor health, suicide, and murder by a slaveholder, overseer, slave patroller, or other dominant person. Separation also occurred within the plantation itself, e.g., by segregating "field slaves" from "house servants," removing children from parents to live together with a slave caretaker, or bringing children fathered by the slaveholder to live in the "Big House." How, then, did the slave family provide solace and identity? "What the family does, and what the family did for African Americans," writes historian Deborah White Gray, "was create a world outside of the world of work. It allowed for significant others. It allowed a male slave to be more than just a brute beast. It allowed him to be a father, to be a son. It allowed women to be mothers and to take on roles that were outside of that of a slave, of a servant."2 When did the enslaved child realize how his or her family life differed from the slave-holder's? How did enslaved adults cope with the forced disintegration of their families? Here we read a collection of texts—two letters, a memoir, and interview excerpts—to consider these questions.

There are many different topics within exploration that students have some background information with.  Topics like the Atlantic Slave Trade and the Columbian Exchange are parts of history that students either have background knowledge on or they are easy for students to grasp.  However, there are other topics, like mercantilism and triangular trade, that students struggle with.  This lesson is designed to be done in an 80-minute period (or more), or over the course of two days.  It allows students some autonomy to work on their own, and to take the notes that they need, but also allows the teacher to lead a portion of the lesson and clarify any quesitons that might arise.

This lesson can be used to introduce students to the concept of different map projections that they might encounter throughout the year.  It helps them to understand that there are many different ways to view the world and that certain views give them different information.

This collection uses primary sources to explore early exploration of the Americas. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Scientists can spend years planning, conducting, analyzing, and publishing the results of their investigations. It’s not surprising that trying to design and conduct scientific investigations in a vastly shorter time span, can often be frustrating for instructors and students, and may lead to misunderstandings about how investigations are done. Students’ attempts at quick investigations are often messy, and data can be inconsistent and fairly inconclusive. But scientists often do “messy” exploratory investigations before doing a full investigation. The goal of an exploratory investigation is to observe and record basic patterns in nature, as well as to explore various methods and improve the ultimate design of an investigation. Exploratory studies can be “quick and dirty” but are important to understanding a phenomenon well enough to develop a testable question and appropriate methods for investigating. Similarly, the goal for students in this activity is not coming up with great data, but to observe and record patterns in nature, and to think about how the investigation could be improved in the future. After being assigned a general topic, such as “exploring where fungi live,” students brainstorm questions, sort questions as testable or not testable, plan a brief exploratory investigation, do it, analyze the results, discuss ideas, and brainstorm ways the investigation could be improved in the future. In a relatively short amount of time, we can give students an experience that’s authentic to field science, while emphasizing how this can lead to a more thorough investigation that answers important questions about the natural world.

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.

This lesson will discuss the details for a possible future manned mission to Mars. The human risks are discussed and evaluated to minimize danger to astronauts. A specialized launch schedule is provided and the different professions of the crew are discussed. Once on the surface, the crew's activities and living area will be covered, as well as how they will make enough fuel to make it off the Red Planet and return home.

The Mission to Mars curricular unit introduces students to Mars the Red Planet. Students discover why scientists are so interested in studying this mysterious planet. Many interesting facts about Mars are revealed, and the history of Martian exploration is reviewed. Students will learn about the development of robotics and how robots are beneficial to science, society and the exploration of space. Details on engineers' involvement in space exploration are presented. Furthermore, students will learn how orbits allow astronauts to move from planet to planet and what type of equipment is used by scientists and engineers to safely explore space. Lastly, the specific details on and human risks for a possible future manned mission to Mars (and back to Earth again!) are discussed.

This activity sets an exciting tone of exploration and discovery, encouraging an inquiry mindset in students that helps establish a community of curious, active learners. Students gain tools to explore the natural world—and are inspired to discover and attempt to explain the abundant nature mysteries that surround us. NSI works well at the start of a field experience, to get students excited about nature mysteries. It provides an opportunity for an instructor to coach students in inquiry skills, by using the language of science and engaging in scientific discussions. For instructors with less experience leading open-ended explorations and discussions, this can be a challenging activity to lead successfully the first time. The write-up includes detailed support, by providing information and strategies for the instructor. Students focus on a mystery object, generate observations, questions, evidence-based explanations and share what they already know from other sources. Once students are familiar with these practices, they can use them to investigate and make explanations about anything they find in nature through their field experience(s).

This lesson will start with a brief history of robotics and explain how robots are beneficial to science and society. The lesson then will explore how robots have been used in recent space exploration efforts. The engineering design of the two Mars rovers, Spirit and Opportunity, will be used as prime examples. Finally, the maneuverability of their robotic arms and the functionality of their tools will be discussed.
