Grade 7

MS-PS1-2

Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

MS-PS1-3

Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.

MS-LS2-1

Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

MS-PS1-4

Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

MS-LS2-2

Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.

October 1, 2018
MS-PS1-5

Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

October 1, 2018
MS-LS2-3

Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

October 1, 2018
MS-PS1-6

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

October 1, 2018
MS-LS2-4

Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

October 1, 2018
MS-PS2-1

Apply Newton?s Third Law to design a solution to a problem involving the motion of two colliding objects.

October 1, 2018
MS-LS2-5

Evaluate competing design solutions for maintaining biodiversity and ecosystem services.

October 1, 2018
MS-PS2-2

Plan an investigation to provide evidence that the change in an object?s motion depends on the sum of the forces on the object and the mass of the object.
