SI
(a) |
Conduct investigations to determine the attraction and repulsion of electrostatically charged materials and represent the results of those investigations using drawings, sketches, tables, charts, and/or other representations. |
(b) |
Describe how results of similar and repeated investigations into the characteristics of static electric charges (e.g., the rubbing together of different substances) may vary and suggest possible explanations for identified variations. |
(c) |
Identify natural and man-made applications of static electric charge and discharge (e.g., lightning, photocopiers, laser printers, air filters, and electrostatic paint sprayers). |
(d) |
Pose questions related to the physical properties of conductors, insulators, simple circuits, and electromagnets (e.g., "How can we determine if an unknown material is a conductor or an insulator?", "How does a switch work in a simple electric circuit?", "What materials work best to create an electromagnet?"). |
(e) |
Make predictions, based on observed patterns of events, related to the physical properties of conductors, insulators, simple circuits, and electromagnets and conduct investigations to test those predictions. |
(f) |
Identify appropriate tools, instruments, and materials (e.g., bulbs, batteries, and wires) to use when investigating the properties of conductors, insulators, simple circuits, and electromagnets and use those tools and apparatus in a manner that ensures personal safety and the safety of others. |
(g) |
Test the conductivity of a variety of solids and liquids, following a given set of procedures, to identify which materials are conductors and which are insulators, and draw conclusions about the types of materials that work best as conductors and which work best as insulators. |
(h) |
Explain the role of switches in electrical circuits. |
(i) |
Describe the operation of an electromagnet and contrast magnets and electromagnets. |
(j) |
Plan a set of steps to carry out a fair test of a science-related idea related to electromagnets, such as how to increase the strength of an electromagnet. |
(k) |
Use evidence gathered through research and observation to answer questions related to the physical properties of conductors, insulators, simple circuits, and electromagnets. |
(l) |
Describe the operation of common technologies based on properties of static electricity, current electricity, or electromagnetism. |
