Performance Expectations
3-5-ETS1-3. Engineering Design. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
4-PS3-2. Energy. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Disciplinary Core Ideas
ETS1.A: Defining and Delimiting Engineering Problems
ETS1.B: Developing Possible Solutions
- 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.
- Tests are often designed to identify failure points or difficulties, which suggest the elements of the design that need to be improved.
ETS1.C: Optimizing the Design Solution
PS4.B: Electromagnetic Radiation
- When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object’s material and the frequency (color) of the light.
- •When light or longer wavelength electromagnetic radiation is absorbed in matter, it is generally converted into thermal energy (heat). Shorter wavelength electromagnetic radiation (UV, X-rays, gamma rays) can ionize atoms and cause damage to living cells.
PS3.B: Conservation of Energy and Energy Transfer
Crosscutting Concepts
Energy and Matter
- Energy can be transferred in various ways and between objects.
- Energy may take different forms (e.g., energy in fields, thermal energy, energy of motion).
Nature of Science: Scientific Investigations Use a Variety of Methods
- Science investigations use a variety of methods and tools to make measurements and observations.
Science and Engineering Practices
Asking Questions and Defining Problems
- Define a simple design problem that can be solved through the development of an object, tool, process, or system and includes several criteria for success and constraints on materials, time, or cost.
- Ask questions that can be investigated and predict reasonable outcomes based on patterns such as cause-and-effect relationships.
Planning and Carrying Out Investigations
- Make observations to produce data to serve as the basis for evidence for an explanation of a phenomenon or test a design solution.
- Make predictions about what would happen if a variable changes.
- Collect data to produce data to serve as the basis for evidence to answer scientific questions or test design solutions under a range of conditions.
- Conduct an investigation and/or evaluate and/or revise the experimental design to produce data to serve as the basis for evidence that meets the goals of the investigation.
Science and Engineering Practices: Analyzing and Interpreting Data
- Analyze and interpret data to provide evidence for phenomena.
- Analyze and interpret data to determine similarities and differences in findings.
- Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.
Constructing Explanations and Designing Solutions
- Apply scientific ideas to solve design problems.
- Generate and compare multiple solutions to a problem based on how well they meet the criteria and constraints of the design problem.
- Apply scientific ideas or principles to design an object, tool, process, or system.
Design or refine a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.
