Systems and Problem Solving is a 22 day introductory unit during which the students use LEGO Technic kits to explore mechanical power transmission principles through the building of realistic, motorized models. Pneumatic systems and computer control will be introduced if time allows.

The unit has three components: the influence technology has on their lives today, and how technology will continue to expand at an exponential rate.

• Each student will develop a technology timeline related to one of the major clusters of technology which will be presented to the class for furthe discussion.
• Using a hands-on, lab style format, concepts related to mechanical systems such as gears, pulleys, and chain drive will be introduced.
• The students apply concepts presented in the labs and learn to use a "systems approach" to problem solving as they
• Design, build and test their solution to a problem presented in class. A design portfolio is used to help organize and direct the problem solving process.

Students who actively participate in this unit will be prepared to meet the following Technology Performance Standards on the MCAS tests as listed in the Science and Technology Frameworks.

• Apply knowledge gained in a series of labs to solve a problem presented in class.
• Make a plan for building a device considering material limitations and conditions the solution must meet.
• Explore and illustrate possible solutions and, from these propose one solution to be built.
• Evaluate solutions based on design criteria.
•  Describe ways that technological devices have improved our quality of life.
• Recognize that while technology can help us to manage societal and environmental problems, it can also have a negative impact on society and the environment
