Item Type(s):
This benchmark may be assessed using:
MC
item(s)
Also Assesses - Clarification :
Students will explain that electrical energy can be transformed into heat, light, and/or sound energy, as well as the energy of motion.
Students will explain that energy from the Sun can be used to heat objects, and that when sunlight is not present, heat may be lost.
Students will identify the flow of heat between hot and cold objects and/or that heat may cause objects to change temperature.
Students will identify common materials that conduct heat well or poorly.
Students will explain that an electrically charged object can attract an uncharged object and/or either attract or repel another charged object without any contact between the objects.
Students will determine that the flow of electricity requires a closed circuit.
Students will identify and/or classify materials that conduct electricity and materials that do not. - Content Limits :
Items will not assess parallel and series circuits.
Items assessing electricity will not refer to electrons or the movement of electrons in producing electrical charge.
Items that refer to positive and negative charges in attraction and repulsion properties must be in the context of static electricity.
Items will not use more than two energy conversions. - Stimulus Attributes :
Scenarios are limited to abiotic systems.
Scenarios referring to energy from the Sun will not use the term radiant. - Response Attributes :
None specified - Prior Knowledge :
Items may require the student to apply science knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge from SC.2.P.10.1.
SC.3.E.6.1 Demonstrate that radiant energy from the Sun can heat objects and when the Sun is not present, heat may be lost.
SC.4.P.11.1 Recognize that heat flows from a hot object to a cold object and that heat flow may cause materials to change temperature.
SC.4.P.11.2 Identify common materials that conduct heat well or poorly.
SC.5.P.10.3 Investigate and explain that an electrically-charged object can attract an uncharged object and can either attract or repel another charged object without any contact between the objects.
SC.5.P.11.1 Investigate and illustrate the fact that the flow of electricity requires a closed circuit (a complete loop).
SC.5.P.11.2 Identify and classify materials that conduct electricity and materials that do not.
- Test Item #: Sample Item 1
- Question: Electric circuits must be properly connected or electricity will not flow. Which of the following shows a properly connected circuit that would allow electricity to flow and light the bulb?
- Difficulty: N/A
- Type: MC: Multiple Choice

STEM Lessons - Model Eliciting Activity
Inventive minds have persisted throughout history. Inventors have improved our lives with inventions created out of a desire to solve a problem or make the quality of peoples' lives better. Our president is concerned that we are not keeping up with other countries in the area of engineering and inventive thinking. Why is this? As students explore famous inventions from around the world throughout history, they will decide what the best inventions of all time are and support their opinion with strong reasons.
In this MEA students are presented with start-up business that needs to buy solar batteries for their business. Students will form engineering teams to review battery choices. Students will understand that solar energy is transferred into electrical energy.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.
