Students will listen to explorers (both historical and present-day) describe their favorite expeditionary gadgets, then choose and justify one piece of technology to bring on an imaginary expedition, drawing from today’s modern tech.
 
Listening activity: How has technology changed exploration?
Technology Search: What technology would you bring on your expedition?
 
Target Grades: 4th – 9th
Estimated time: 60 minutes
Subjects: English Language Arts, Engineering and Technology
Topics: History of Science, Innovation, Technology

For as long as explorers have been venturing into unknown territories, they have relied on the best science and technology of their day to survive the journey. Technology, the application of scientific understanding to solve a problem, is found in nearly every type of expeditionary gear, from the synthetic materials that make Arctic coats warm and waterproof to the food preservation techniques that have allowed astronauts to stay nourished in orbit.
 
As new technologies have emerged through scientific discovery, more advanced equipment has entered the field to overcome risks and inconveniences associated with exploration. By looking through the packing lists of famous expeditions, you can usually glimpse an era’s most advanced technology.

How has new technology changed exploration?

Each of the following excerpts is from an interview with a real explorer about his or her experience in the field. Listen for their descriptions of the advanced equipment and technology that they use, and consider the following questions: What problem has their technology solved? How has their technology made it easier for them to safely explore and make discoveries?

As you listen and watch, record your observations on this nifty technology and exploration graphic organizer (pdf version).

What technology would you bring?
The consequences of being poorly prepared in the field can be disastrous. Many famous exploratory expeditions, such as Colonel Percy Fawcett’s last journey into the Amazon, perished without a trace. As David Grann describes in his book The Lost City of Z, even Fawcett’s successful trips into the Amazon left many of his traveling companions lost, suffering, or dead from disease, starvation, and violence. If they had been traveling with today's technology, perhaps their fates would have been different. 
 
If you were to plan your own expedition, where would you go, and what one piece of technology would you bring? What problems would your chosen technology solve? In your response, describe how the environment and risks associated with your chosen destination factored into your decision.

Common Core Standards:

CCSS.ELA-LITERACY.W.8.7
Conduct short research projects to answer a question (including a self-generated question), drawing on several sources and generating additional related, focused questions that allow for multiple avenues of exploration.

CCSS.ELA-LITERACY.W.8.8
Gather relevant information from multiple print and digital sources, using search terms effectively; assess the credibility and accuracy of each source; and quote or paraphrase the data and conclusions of others while avoiding plagiarism and following a standard format for citation.

CCSS.ELA-LITERACY.W.9-10.8
Gather relevant information from multiple authoritative print and digital sources, using advanced searches effectively; assess the usefulness of each source in answering the research question; integrate information into the text selectively to maintain the flow of ideas, avoiding plagiarism and following a standard format for citation.

CCSS.ELA-LITERACY.SL.9-10.2
Integrate multiple sources of information presented in diverse media or formats (e.g., visually, quantitatively, orally), evaluating the credibility and accuracy of each source.

Next Generation Science Standards:
High School: Scientific Investigations Use a Variety of Methods
  • Scientific investigations use a variety of methods, tools, and techniques to revise and produce new knowledge.
  • Scienctific investigations use diverse methods and do not always use the same set of procedures to obtain data.
  • New technologies advance scientific knowledge.
High School: Science Is a Human Endeavor
  • Technological advances have influenced the progress of science, and science has influenced advances in technology.
  • Science and engineering are influenced by society, and society is influenced by science and engineering.
Middle School: Science Is a Human Endeavor
  • Scientists and engineers rely on human qualities such as persistence, precision, reasoning, logic, imagination and creativity.
  • Advances in technology influence the progress of science, and science has influenced advances in technology.
