Engineering Design

Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.

Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.

Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.

Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals

Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth's 4.6‐billion‐year‐old history.

Develop a model to describe the cycling of Earth’s materials and the flow of energy that drives this process.

Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.

Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.

Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.

Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function

Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.

Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
