changes in particle motion, temperature, and phase (state) change
density is a property of matter
mixtures are combinations of substances.
fields exist between objects exerting forces on each other even though the objects are not in contact.
Chemical properties and Changes
atomic composition of simple molecules
synthetic materials come from natural resources and impact society.
determine if a chemical reaction has occurred.
number of atoms does not change in a chemical reaction
Forces and Motion
apply Newton’s Laws in various investigations and applications
gravitational interactions between objects with different masses
Energy
electric and magnetic forces.
relationships between the kinetic energy and the mass of an object as it relates to the speed of an object.
objects interacting at different distances changes, different amounts of potential energy are stored in the system.
design, construct, and test a device that either minimizes or maximizes thermal energy transfer
when work is done on or by a system, the energy of the system changes as energy is transferred to or from the system.
energy can be transferred by electric currents.
use mathematical representations to describe waves that include frequency, wavelength, and how the amplitude of a wave is related to the energy in a wave.
waves are reflected, absorbed, or transmitted through various materials
Engineering Design
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 competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
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.
Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy during a chemical and/or physical process.
