Description

Students explore how various energy sources can be used to cause a turbine to rotate and then generate electricity with a magnet.

HS-PS3-3 Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.

MS-ETS1-1 Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions

Evaluate the impact of new data on a working explanation and/or model of a proposed process or system.

Ask questions to clarify and/or refine a model, an explanation, or an engineering problem.

Define a design problem that involves the development of a process or system with interacting components and criteria and constraints that may include social, technical and/or environmental considerations.

Construct an explanation using models or representations.

Optimize performance of a design by prioritizing criteria, making tradeoffs, testing, revising, and re-testing.

Make and defend a claim based on evidence about the natural world or the effectiveness of a design solution that reflects scientific knowledge, and student-generated evidence.

Develop or modify a model—based on evidence – to match what happens if a variable or component of a system is changed.

Design a test of a model to ascertain its reliability.

Develop, revise, and/or use a model based on evidence to illustrate and/or predict the relationships between systems or between components of a system.

Communicate scientific and/or technical information (e.g. about a proposed object, tool, process, system) in writing and/or through oral presentations.

Communicate scientific and/or technical information or ideas (e.g. about phenomena and/or the process of development and the design and performance of a proposed process or system) in multiple formats (including orally, graphically, textually, and mathematically).

Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.

Plan an investigation or test a design individually and collaboratively to produce data to serve as the basis for evidence as part of building and revising models, supporting explanations for phenomena, or testing solutions to problems. Consider possible variables or effects and evaluate the confounding investigation’s design to ensure variables are controlled.

Although energy cannot be destroyed, it can be converted to less useful forms—for example, to thermal energy in the surrounding environment.

There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem.

When the motion energy of an object changes, there is inevitably some other change in energy at the same time.

Humanity faces major global challenges today, such as the need for supplies of clean water and food or for energy sources that minimize pollution, which can be addressed through engineering. These global challenges also may have manifestations in local communities.

Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem.

Energy cannot be created or destroyed—it only moves between one place and another place, between objects and/or fields, or between systems.

Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions—including energy, matter, and information flows—within and between systems at different scales.

Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy and matter flows within systems.

Energy may take different forms (e.g. energy in fields, thermal energy, energy of motion).

Models are limited in that they only represent certain aspects of the system under study.

Systems can be designed to do specific tasks.
