While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Because engineers and scientists have different objectives, they follow different processes in their work. Scientists perform experiments using the scientific method; whereas, engineers follow the creativity-based engineering design process.

What happens when you introduce an architect who builds "Transformer"-like self-assembling structures to an urban agriculturalist who makes futuristic farms and an engineer who designs nuclear reactors that eat radioactive waste? Watch National Geographic Emerging Explorers Skylar Tibbets, Caleb Harper, and Leslie Dewan share stories of how they're inventing tomorrow's realities in the fields of architecture, agriculture, and nuclear engineering.

Different disciplines follow different versions of the inquiry process. Graphic comparing: problem solving, scientific method, writing process, computation, theater, and engineering design.

In this case study, we'll follow the process of developing an edible vaccine for the hepatitis B virus and explore practical details of genetic engineering techniques. 

If you were limited to choosing only three crops to sustainably farm in an arid, inhospitable environment, what would they be and how would you decide? This interrupted case study places students in the role of a proposed self-sufficient Martian colony that requires an optimized profile of food crops. After students form small groups, they discuss the factors that affect sustainability of a food supply, determine criteria for selection of crops to grow, and rank crops using these criteria. Lists of criteria and of foodstuffs are provided, but the case can easily be transformed into a problem-based learning (PBL) case by having students research and generate their own lists. The case includes questions that walk students through the selection process and require them to explain why they chose their criteria and how those criteria apply to their chosen foods. The case is designed for undergraduate students at the introductory level in courses in astronomy/astrobiology, food science/nutrition, agricultural engineering, or any discipline where sustainability is a key theme.

The NISE Network offers a variety of programs and activities designed for small and large groups in different settings. Educational programs are a great way to introduce audiences to nanoscale science, engineering, and technology. Presenters can choose a format and topic that is appropriate for their audience. Facilitated experiences foster visitor conversation and interaction, and allow educators to adjust the science content, pace, and delivery style to suit their audience.

Nature's best kept secret is a wonder molecule called RNA. It is central to the origin of life, evolution, and the cellular machinery that keeps us alive. In this Lab you'll play the role of a molecular engineer by solving RNA folding puzzles. Then take your skills to Eterna, where you can design RNAs that could be at the heart of future life-saving therapies.

inquiryHub high school and middle school curricula are aligned to the Framework and guided by the Next Generation Science Standards (NGSS). Using research-based approaches to teaching science in a deeply digital environment, students contribute resources, observations, data, and analyses to solve larger scientific problems.  inquiryHub curricula are designed to go beyond traditional science content. By focusing on phenomena relevant to students' lives and communities, the coursesprovides opportunities to authentically engage with science and engineering practices.

THE prospect of creating intelligent designer babies has been the subject of ethical debate for decades, but we have lacked the ability to actually do it. That may now change, thanks to a new method of testing an embryo's genes that could soon be available in some IVF clinics in the US, New Scientist can reveal.

Designer babies, the end of diseases, genetically modified humans that never age. Outrageous things that used to be science fiction are suddenly becoming reality. The only thing we know for sure is that things will change irreversibly.

Biologists at the Massachusetts Institute of Technology have created a genetically modified version of a common bacteria found in the gut that can sense the environment there and fight disease. And when this designer bacteria works, the proof is in the poop - glowing poop. (In this case, mouse poop.)
