Electricity in a closed circuit flows through the circuit and transfers energy to the receiver. |
A closed circuit is created with a continuous path through the: (1) top of the battery, (2) bottom of the battery, (3) bottom of the bulb, and (4) threaded side of the bulb. Battery has electricity Top has metal bump Bottom has metal plate Wire has plastic coating Metal (copper) inside the wire Light bulb has a metal tip on the bottom Light bulb has metal threads on the side Light bulb has glass on the top Light bulb has a filament inside Light bulb lights Electricity passes through the bulb |
Light bulbs and batteries have no interactions.
Energy flows from the battery to the light bulb like water from a hose. There must be a circle for the energy to flow. |
Diagnosis Summative Ask for all possible ways to make a circuit that lights the bulb. Ask how energy is transferred. Generative |

Scientific inquiry requires verifiable evidence, testable hypotheses and logical reasoning in the search for unbiased theories. |
Can think of a way of lighting the
bulb, try it, and observe if it lights.
There may be more than one way to light the bulb. Several ways can be tested. A pattern may be used to generate different ways. Other people may suggest different ways to light the bulb that can be tested and checked with an experiment. |
Some people are smart and just know if it will work. People get their ideas from books. |

Models are representations of a real system that can be used to explain and predict how systems interact. |
Pictures or symbols represent objects. A symbol represents an energy source and receiver. Energy transfer is represented by a continuous path. The continuous path must enter and leave both the receiver and source. The pattern described or illustrated in the model can be transformed in part and not changed in other parts. Essential parts of the system are two terminals on the battery and two terminals on the bulb. |
Each circuit is unique and there are no common elements among different circuits. Models are like pictures. Systems can not be understood. |
Diagnosis Summative Generative How else might you use models? |

Scientists are curious and persistent in their quest to solve and understand problems. |
The bulb will light. If I just keep varying the positions of the objects a method of lighting the bulb can be found through experimentation. | There are not enough objects in the system to light the bulb. |

I am capable of using science to understand the world. |
If I just try some ideas I can figure
out a way to light the bulb.
If one way doesnt work I can try another. I found one way I might be able to find another. I can make all the circuits that were discussed in class. I can understand how the transfer of energy could happen from a source to a receiver. |
I am not smart enough to understand how to solve problems. |
Diagnosis Summative Generative Do you think you are good at learning and solving problems? |
|
Scientists share ideas to check their data and reasoning and help everyone understand our world. | Other people have ideas different than me.
When I listen to people who agree with me, I become more confident in what I know. Discussions help me understand explain to others better. I can help other people learn too. |
I know everything and dont need to share with others. other peoples ideas are dumb. |
