Biosuit Design Challenge What is a Biosuit A

Biosuit Design Challenge

What is a Biosuit? • A Biosuit is any kind of protective suit that enables a human to maintain homeostasis while working in an environment that would not support human life. • Examples: Space Suit, Hazmat Suits, Wet Suits etc.

Why do we need Bio. Suits? • The systems of the body participate in maintaining homeostasis, that is, the relative constancy of the internal environment despite external environmental changes. • What does each system need in order to support the human body in maintaining homeostasis? – – – – Respiratory System. Circulatory System. Digestive System. Immune System. Excretory System. Integumentary System. Nervous System- http: //www. mhhe. com/biosci/genbio/maderbiology/supp/homeo. html

Where do we use Biosuits? • Biosuits are used in environments where the temperature, air pressure, amount of oxygen in the atmosphere and other factors are not conducive to a human maintaining homeostasis. • Examples: The ocean, space, Arctic regions, hazardous environments etc.

Vocabulary • Bio: prefix- of or relating to life • Accommodations: the process of adapting or adjusting to someone or something • Vacuum: a space entirely devoid of matter.

Vocabulary Continued • Homeostasis: The tendency of the body to seek and maintain a condition of balance or equilibrium within its internal environment, even when faced with external changes • Engineer: a person who designs, builds, or maintains engines, machines, or public works. • Engineering Design Process: the process of planning a study to meet specified objectives.

Vocabulary Continued • Biosuit: any kind of protective suit that enables a human to maintain homeostasis while working in an environment that would not support human life. • Hazardous: risky; dangerous

Vocabulary Continued • Procurement: the action of obtaining or procuring something • Budget: an estimate of income and expenditure for a set period of time • Constraint: a limitation or restriction. • Problem Solving: the process of finding solutions to difficult or complex issues.

Vocabulary Continued • Collaboration: the action of working with someone to produce or create something.

Vocabulary Continued • Neoprene- a family of synthetic rubbers. Exhibits good chemical stability, and maintains flexibility over a wide temperature range. (used in wet suits, laptop sleeves, knee braces etc. ) • Mylar- a polyester film used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation.

Presentations-Slide Show q. Scientific research and overview of the features of your Biosuit. q. Budget analysis that proves your model is economically feasible. q. Explanation for how your model would support homeostasis in a human being. q. Descriptions of how scientists and engineers would be able to work while wearing your Biosuit. q. Background information about your assigned environment and career

Presentations-Tell Your Story • Include all members. • Create a back story that is creative and maybe even funny about your group. • Talk about your design, and explain what each feature is and how it would be represented if you had real materials.

Presentations-Performance Task • Explain what your human model is doing as they perform the task. • Describe how the features you created are helping to complete the task.

Your Biosuit-Material Comparison • Could aluminum foil represent a bullet proof layer or Mylar? • Could felt represent nylon layers used in the space suit? • Could rubber represent neoprene? Be creative and explain the materials you use, and how they compare to “real world” materials.
