IAR Research Simulation - Energy Story, Squishy Circuits

1. Part A: Why does the author most likely place the information in paragraphs 1–2 at the beginning of “Energy Story”?

• to encourage the reader to learn how electronic devices are made

• to show the reader how different machines can improve our lives

• to draw the reader in by showing how electricity affects everyone

• to teach the reader how to use electricity in different settings

2 Part B: Which sentence from"Energy Story" best supports the answer in Part A?

• "Each atom has a specific number of electrons, protons, and neutrons." (8)

• "So, if an atom had six protons, it should also have six electrons." (9)

• "The charge is passed from atom to atom when electricity is 'passed.'" (12)

• "Most metals -- like copper, aluminum or steel -- are good conductors." (22)

3 Part A: Which sentence best states the central idea of paragraphs 21–22 in “Energy Story”?

• Materials that are insulators and conductors have a high resistance to electricity.

• It is more difficult for electricity to pass through insulators than conductors.

• Insulators and conductors are able to generate a high amount of electricity

• Electrons move through rubber easier than they move through metal.

5: Use what you learned from the video to place check marks next to all of the activities that are needed to successfully turn on an LED light. Note that some listed are incorrect.

• Connect the wires of an LED light to the wires of a battery pack

• Push one wire of an LED light into a piece of salty dough. Plug the other wire of an LED light into a piece of sugary dough.

• Divide a chunk of salty dough into two separate pieces

• Connect the wires of a battery pack to salty dough

• Plug one wire of an LED light into a piece of salty dough. Plug the other wire of an LED light into another piece of salty dough.

6 Part A: As it is used in the article, what does the word solution mean?

• an ability to combine smaller parts

• an answer to a problem

• a capacity to carry a stronger charge

• a liquid mixture
