Knowledge

Students know:
  • Human activities in agriculture, industry, and everyday life can have major effects, both positive and negative, on the land, vegetation, streams, ocean, air, and even outer space.
  • Individuals and communities are doing things to help protect Earth's resources and environments.
  • Research on a problem should be carried out before beginning to design a solution.
  • Testing a solution involves investigating how well it performs under a range of likely conditions.
  • At whatever stage, communicating with peers about proposed solutions is an important part of the design process, and shared ideas can lead to improved designs.

Skills

Students are able to:
  • Use grade-appropriate information from research about a given problem, including the causes and effects of the problem and relevant scientific information.
  • Generate at least two possible solutions to the problem based on scientific information and understanding of the problem.
  • Specify how each design solution solves the problem.
  • Share ideas and findings with others about design solutions to generate a variety of possible solutions.
  • Describe the necessary steps for designing a solution to a problem, including conducting research and communicating with others throughout the design process to improve the design [note: emphasis is on what is necessary for designing solutions, not on a step-wise process].

Understanding

Students understand that:
  • Engineers improve existing technologies or develop new ones to: increase benefits, decrease known risks, and/or meet societal demands.
