New Haven Public Schools requires science teachers to use Connecticut state standards, with an emphasis on inquiry standards, but encourages teachers to consult current national standards that the state derived theirs from, and the likely to be implemented Next Generation Science Standards which have been proposed but not yet approved by the state. This unit is designed to have students practice and evaluate student inquiry skills.
CT SCIENCE DINQ 4: Design and conduct appropriate types of scientific investigations to answer different questions.
18
CT SCIENCE DINQ 6: Use appropriate tools and techniques to make observations and gather data.
18
CT SCIENCE DINQ 8: Use mathematical operations to analyze and interpret data, and present relationships between variables in appropriate forms.
18
CT SCIENCE DINQ 9: Articulate conclusions and explanations based on research data, and assess results based on the design of the investigation.
18
CT SCIENCE DINQ 10: Communicate about science in different formats, using relevant science vocabulary, supporting evidence and clear logic.

CT SCIENCE 9.2: The electrical force is a universal force that exists between any two charged objects.
18
CT SCIENCE 9.4: Atoms react with one another to form new molecules. Atoms have a positively charged nucleus surrounded by negatively charged electrons. The configuration of atoms and molecules determines the properties of the materials.

NEAP P12.1: Differences in the physical properties of solids, liquids, and gases are explained by the ways in which the atoms, ions, or molecules of the substances are arranged and the strength of the forces of attraction between the atoms, ions, or molecules.
18
NEAP P12.23: Electric force is a universal force that exists between any two charged objects. Opposite charges attract while like charges repel. The strength of the electric force is proportional to the magnitudes of the charges and inversely proportional to the square of the distance between them. Between any two charged particles, the electric force is vastly greater than the gravitational force.

NGSS HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
13
NGSS HS-PS2-5: Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. [Assessment Boundary: Assessment is limited to designing and conducting investigations with provided materials and tools.]
13
NGSS HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
13
NGSS HS-PS3-5: Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
