  2. What does an engineer do? • Solve problems, and shape the future! • Create and design new “things” essential to health, happiness and safety: • Chemical things – food, medicine, shampoo, fuels… • Building things – bridges, skyscrapers, roads… • Technology things – iPods, Cameras, electronic gadgets… • Fun things – toys, roller coasters, sporting goods... • Important things – water systems, medical devices and tools… • Much, much more….the list is endless images.businessweek.com www.wistatefair.com www.gettyimages.com ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  3. How do engineers do this? • Help others by solving all sorts of problems. • Use one of their most important tools: their own creativity. • Work in design teams. • Use cool tools such as computers, microscopes, testing machines, etc. • Communicate with lots of people about problems they need solved. • Share ideas and solutions with others through presentations and/or writing. www.engineeringmessages.org ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton underGrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  6. Engineering Design Problem • In Africa, two out of five people do not have clean water. Because so much of Africa’s water is contaminated, many people struggle to stay healthy, go to school/work, grow food, and build houses. • The villagers do not have a lot of money or materials available to them, so it is a challenge for them find a low-cost, simple way to clean their water. • You and your team know that a source for clean water would help solve these problems and improve the lives of thousands of people. So you decide to plan a trip to an African village and help.

  7. Engineering Design Challenge Today you will be a civil engineer – You will design, build and test a filtration system! • Before leaving for Africa, your team’s challenge is to design, build, and test a filtration system that could be used for removing harmful pollutants/contaminants from water. • It is important to conserve clean water, so beads and marbles will symbolize contaminated water while testing your designs. ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  8. Design Goals • Build a filtration system that will Prototype tested by A mixture of beads and marbles will be used to symbolize water during filtration system by using. • Beads represent clean, drinkable water. • Marbles represent contaminates in the water. • Only provided materials provided may be used: a cup, toothpicks, rubber bands , string, and cardstock. • The cup must be able to collect and hold clean water (beads). The design can be attached to the cup. • Only clean water (beads) should fall into the cup, while the contaminated water (marbles) remain above the filter. • Have fun!!

  9. Materials ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  10. Design Testing • Pour a mixture of marbles and beads onto the filter. • A successful design will: • allow only beads to collect in the cup. • filter (block) all marbles from entering the cup.

  11. Engineering Design Process ASK: What is the problem? How have others approached it? What are your constraints? IMAGINE: What are some solutions? Brainstorm ideas. Choose the best one. PLAN: Draw a diagram. Make lists of materials you will need. CREATE: Follow your plan and create something. Test it out! IMPROVE: What works? What doesn't? What could work better? Modify your designs to make it better. Test it out! www.teachengineering.org ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  12. Engineering Design Process • Imagine(10 min.) • INDIVIDUALLY: observe available materials, and brainstorm and write design ideas (5 min.) • TEAM: share individual ideas (5 min.) • Plan(5 min.) • Choose and sketch a team design plan • Create(10 min.) • Gather materials • Construct your team design plan • Improve and Test (10 min.) ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  13. Design reflection writing • Did your water filter remove harmful pollutants/contaminants from the water? Write a sentence or two about why your water filter did or did not remove harmful pollutants/contaminants from the water. • Write a sentence or two about how you will improve your water filter. ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  14. Design Reflection • What went well? Not so well? Why? • What aspects of other team designs stood out to you? • Did other designs give you ideas for ways to improve your design? • What modifications would you make if we had time to complete the design challenge again? • How does having the ability to filter contaminants from polluted water benefit an environment’s biotic factors (living things), including humans? • Why is it important to protect Earth’s water? ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.

  15. Wrap Up • What ideas do you have for engineering a better world? • How can you turn ideas into reality? ThismaterialisbaseduponworksupportedbytheEngineeringScienceFoundation of Dayton under GrantNo.AD2018-0001andthrough a 2017-18 grant from the Marianist Foundation.
