[RCA-ST.6-8.3] - Follow precisely a multi-step procedure when carrying out experiments, taking measurements, or performing technical tasks.
[6.PS.1.6] -
Plan and conduct an experiment involving exothermic and endothermic chemical reactions to measure and describe the release or absorption of thermal energy. Clarification Statements: Emphasis is on describing transfer of energy to and from the environment. Examples of chemical reactions could include dissolving ammonium chloride or calcium chloride.
[6.PS.1.8] -
Conduct an experiment to show that many materials are mixtures of pure substances that can be separated by physical means into their component pure substances. Clarification Statement: Examples of common mixtures include salt water, oil and vinegar, milk, and air.
[6.ETS.2.2] -
Given a design task, select appropriate materials based on specific properties needed in the construction of a solution.*
Clarification Statement: Examples of materials can include metals, plastics, wood, and ceramics.
[8.PS.2.2] -
Provide evidence that the change in an object’s speed depends on the sum of the forces on the object (the net force) and the mass of the object.
Clarification Statement: Emphasis is on balanced (Newton’s first law) and unbalanced forces in a system, qualitative comparisons of forces, mass, and changes in speed (Newton’s second law) in one dimension. State Assessment Boundaries: State assessment will be limited to forces and changes in motion in one dimension in an inertial reference frame and to change in one variable at a time. The use of trigonometry is not expected in state assessment.
