Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object. ||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other. [Examples: the electrical forces between a charged rod and pieces of paper; the force between 2 permanent magnets, the force between an electromagnet & steel paperclips, Focus on forces produced by objects that can be manipulated by students, & electrical interactions – limited to static.] “||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Define a simple design problem that can be solved by applying scientific ideas about magnets. [ Examples: make a door latch; creating a device to keep two moving objects from touching each other.] ||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Make observations & measurements to identify materials based on their properties. [Examples of properties: color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, & solubility; density is not intended as an identifiable property.]||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. ||Next Generation Science Standards||Middle School||Physical Science||Motion and Stability: Forces and Interactions |||Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact. [Assessment is limited to electric and magnetic fields, and limited to qualitative evidence for the existence of fields.] ||Next Generation Science Standards||Middle School||Physical Science||Motion and Stability: Forces and Interactions
