3Technology in a Bag What is technology? What does your technology do? What problem does it solve?How else could you use it?What materials are used to make it?What other material could be used to make it?Hand out mystery bags. Have participants open the bag, pass the object and examine it. As they examine their technology, ask the groups to take 5 to 10 minutes to discuss these questions.After 5 – 10 minutes ask three to five groups to share their technology with the whole group. Also ask some of these questions while the groups are presenting:How is the shape of the technology important to its function?What are the benefits of one material over another?What are the properties of the materials used to make the technology? How do these properties contribute to its function?
4What is technology? Technology is: Anything human-made or used to solve a problem or to fulfill a desireTechnology can be an object, system or a process.Can you identify a technology in this room that is a:SystemProcessDefine technologyDifferentiate a system from a processProcess: recipeSystem: juice box – because the container and straw function independently to contain and to dispense the juice
5What can you do with a spoon? What is an alternative function for this spoon?If you were to think about redesigning this spoon so that it functioned better as a ______, what you change and why?Who does this kind of work? Who uses their knowledge of science, materials properties and ergonomics to design technologies?Hold up a plastic spoon – this is your example of technology
6Science, Technology, Engineering A body of knowledgeSeeks to describe and understand the natural world and its physical propertiesScientific knowledge can be used to make predictionsScience uses a process--the scientific method--to generate knowledgeEngineering:Design under constraintSeeks solutions for societal problems and needsAims to produce the best solution given resources and constraintsEngineering uses a process--the engineering design process--to produce solutions and technologiesTechnology:The body of knowledge, processes, and artifacts that result from engineeringAlmost everything made by humans to solve a need is a technologyExamples of technology include pencils, shoes, cell phones, and processes to treat water
7Comparison of typical processes Scientific Inquiry1.) Observation and form a question2.) Hypothesis & procedure3.) Conduct an experiment4.) Refine hypothesis and experiment again5.) Form a conclusion and communicate itRESULT: Facts and theoriesEngineering Design1.) Define the problem and resources available2.) Develop a design3.) Test the design4.) Modify the design and test again5.) Analyze the design and use or market itRESULT: Products and processes
8Engineering at work…Ms. Campbell-Klett wants to put on display some of the Rainbow Lab Cylinders that her students have made in the 9th grade physical science in the large display cases near the Trojan head.What is the problem?In order to solve this problem, what do you need to know?Introduce the Tower Activity with a story.Ms. Campbell-Klett wants to put on display some of the Rainbow lab grad cylinders that students have made in 9th grade physical science in the large display cases near the Trojan head.What is the problem? (Too small to see, no shelves, etc)
9Tower ActivityConstruct a tower to hold up a student rocket, the tower must be:At least 2 feet tallStructure must support a stapler for 10 secondsCannot test the structure until the deadline is reached (30 minutes) and cannot be anchoredSupplies your group may use:1 pack of 100 index cardsScotch tapeScissors15 minutesWander around the groups asking questions: What are you designing? Why do you think it will be successful?
1030 minutes Tower Activity 15 minutes Wander around the groups asking questions: What are you designing? Why do you think it will be successful?
11Tower Activity What is similar about these solutions? What is different about them?After testing, what would you do if given the chance to improve your tower?After the deadline, have all groups look at the various towers. And ask the first 2 questions. Then with the entire group watching let each test their design. Then ask the 3rd question above.
12Action WordsWhat are some action words that describe what you did during the design process?After the deadline, have all groups look at the various towers. And ask the first 2 questions. Then with the entire group watching let each test their design. Then ask the 3rd question above.
13Rocket lab redesignMs. Campbell-Klett wants to find a way to make the film canister rockets go higher. Brainstorm ideas in your lab groups for how this could look.
