Inquiry Activity..

For your blog post, please identify the NGSS Performance Expectations, Disciplinary Core Ideas, CrossCutting Concepts, and Science and Engineering Practices that are relevant to your Inquiry Activity.

Identify the NGSS Performance Expectations: 

Forces and Interactions

Students who demonstrate understanding can:

Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other

Disciplinary Core Ideas

PS2.A: Forces and Motion

• Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object’s speed or direction of motion. (Boundary: Qualitative and conceptual, but not quantitative addition of forces are used at this level.) (3-PS2-1)
• The patterns of an object’s motion in various situations can be observed and measured; when that past motion exhibits a regular pattern, future motion can be predicted from it. (Boundary: Technical terms, such as magnitude, velocity, momentum, and vector quantity, are not introduced at this level, but the concept that some quantities need both size and direction to be described is developed.) (3-PS2-2)
• PS2.B: Types of Interactions

Objects in contact exert forces on each other. (3-PS2-1)

Electric and magnetic forces between a pair of objects

do not require that the objects be in contact. The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. (3-PS2-3),(3-PS2-4)

Cross Cutting Concepts

Patterns

Patterns of change can be used to make predictions. (3-PS2-2)

Cause and Effect

Cause and effect relationships are routinely identified. (3-PS2-1)

Cause and effect relationships are routinely identified, tested, and used to explain change. (3-PS2-3

Connections to Engineering, Technology, and Applications of Science

Interdependence of Science, Engineering, and Technology

Scientific discoveries about the natural world can often lead to new and improved technologies, which are developed through the engineering design process. (3-PS2-4)

Science and Engineering Practices that are relevant

Asking questions and defining problems in grades 3–5 builds on grades K–2 experiences and progresses to specifying qualitative relationships.

Ask questions that can be investigated based on patterns such as cause and effect relationships. (3-PS2-3)

Define a simple problem that can be solved through the development of a new or improved object or tool. (3-PS2-4)

Planning and Carrying Out Investigations

Planning and carrying out investigations to answer questions or test solutions to problems in 3–5 builds on K–2 experiences and progresses to include investigations that control variables and provide evidence to support explanations or design solutions.

Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence, using fair tests in which variables are controlled and the number of trials considered. (3-PS2-1)

Make observations and/or measurements to produce data to serve as the basis for evidence for an explanation of a phenomenon or test a design solution. (3-PS2-2)
